FLOCK MANAGEMENT DURING THE REARING PERIOD

1. FLOCK MANAGEMENT DURING THE REARING PERIOD
Rearing is a key period for successful laying performances. During this period it is necessary to reach the target
bodyweight and flock uniformity to prepare the birds for the production period. A special care has also to be given to
the development of the digestive tract in order to prepare for the fast increase in consumption at the beginning of the
production period. A well-managed rearing period has positive effects on:
• Quick adaptation to production system (onset of lay, floor eggs prevention)
• Egg production (peak of lay and persistency)
• Egg quality (egg weight, egg uniformity, shell strength)
• Liveability
• Fertility
To achieve those objectives, it is necessary to respect the following basics:

• Management (stocking density, drinker and feeder space, water, beak trimming…)
• Climate conditions
• Pullet training
• Lighting programme
• Monitoring bodyweight and uniformity
• Nutrition
• Biosecurity and vaccination

STARTING UP STRATEGY
ALL SYSTEM
• Before chicks arrive, feed should be accessible to the chicks. Feeders should be well filled and feed should be
spread over chick paper especially close to the drinking lines. This stimulates the chicks to use the drinking
equipment.
• Feed must be regularly renewed to keep it fresh and attractive.
• Before arrival the drinking lines must be checked, so that fresh water is provided and leakage is prevented.
• Triggering the nipples or water cups encourages the birds to drink
• Unload the chicks close to drinkers and feeders.
SYSTEM SPECIFICITIES
• Floor system:
o Additional starter drinkers and feeders can be used in the first 2 weeks
o If brooding takes place in only part of the house, do not exceed a stocking density of 20 chicks
per available m2. Thus allowing chicks to spread quickly over the whole house within the first 7
days.
o In case of use of circular brooder guards (rings or surrounds):
 Choose a diameter of 3 to 4 m at day-old but ensure the ring can be enlarged 48 hours
after the arrival
 Ensure the surround can be easily removed after the birds have familiarised themselves
with the location of the drinker and feeder systems. Usually, guards can be removed 5 to
7 days after arrival.
• Cage system
o Use soft mat and/or paper on the bottom of the cage to improve the ease of movement and comfort
of the chick for the first few days. Paper must be removed by day 7 at the latest.
CLIMATE STRATEGY
Before and after arrival and starting up of the chicks, the below information can be used as guidelines for optimal
performance. Be aware that those setting depends highly on local climate conditions and must be adapted
accordingly.

 Before chicks arrival:
• After hatch, a chick is poikilotherm. This means that it can’t fully regulate its own bodytemperature.
Therefore it is important that the housing climate is supported at such a way that the thermoneutral
bodytemperature of 40⁰C is achieved.
• Raise the house temperature at least 36 hours before chick arrival to 29°C-30°C
• Pre-heat the whole house 30 to 40 hours prior to chick arrival ensuring the floor and system is fully
warmed before placement to 35oC.
 After chicks arrival:

• Never overheat the chicks and give them a choice within the desired temperature range.
• Take into account the temperature at chick level.
• Depending on the brooder design, place the brooders high enough above the litter (at least 1.5 m) at an
angle, to allow for uniform distribution of the chicks.
Check the chicks body temperature after start up to adjust the house temperature by gently touching the
chick cloaca with the probe of an ear thermometer. The optimal chick body temperature is 40-41 °C. It is
important to measure the body temperature of a sufficient numbers of chicks distributed in different parts
of the house.
Photos: Control of chicks temperature
• Check the distribution and behaviour of the chicks to enable you to adapt and manage the temperature
of the House:
o Good distribution and activity  correct temperature and climate
o Chicks cuddle and/or avoid large areas of the barn  temperature is too low or presence of air draft
o Chicks are panting and are lying on the ground with their wings spread  temperature is too high

Temperature and relative humidity are important climate parameters, but not the only ones. An optimal ventilation in
the rearing house is important to obtain the right oxygen level, a uniform air and temperature disitribution and for the
removal of dust and ammonia. If mechanical ventilation is used, the ventilation settings are calculated based on:
• The right temperature based on the age of the chicks
• Constant RH (between 50-70%). Too dry air can damage the oral epithelium.
• An O2 level around 20%
o CO2 with direct heating < 5000 ppm
o CO2 with indirect heating < 3000 ppm
o CO < 10 ppm
o Ammonia< 10 ppm
o Inspirable dast < 3,5 mg/m³
Based on those settings the recommendations for minimum ventilation results in:
• 0,08 m³/bird/hour at arrival
• 0,7 m3 per kg housed in animal, when outside temperature colder than 10⁰C.
• 1,0 m3 per kg housed animal, when outside temperature warmer than 10⁰C.
GRIT AND GRAIN

To maintain an active feeding behaviour and to help the development of the digestive tract and encourage the birds
to scratch the litter, it is advised to give grit and grain to the birds from 4 to 5 weeks of age:
• Grit (insoluble stone particles of 2 to 4 mm): 1 to 3 g per week per bird, distributed over 2 or 3 days.
• Grain (broken maize, wheat): 3 g per bird every day, or every other day

LIGHTING PROGRAMME
2. LIGHTING PROGRAMME
GENERAL RULES
Sexual maturity and production are largely influenced by the changes in day length to which pullets are exposed.
Carefully chosen lighting programmes will help to optimise the performance of breeders stocks. Sexual maturity and
bodyweight at sexual maturity influence the production, the egg size and the liveability, so the total number of hatching
eggs per hen housed.
It is difficult to advise a universally optimum and perfect lighting programme. The following lighting programmes are
examples and have to be considered as a guideline to help formulate a lighting programme adapted to your own
situation;
To establish your own lighting programme, it is important to take into account the following factors:
• Your location (changes in light duration (day length) during the year)
• The characteristics of the rearing unit (light-controlled, semi-dark or open house type)
• Season of the year (increasing or decreasing day length)
• Temperature (light duration at the highest temperature)
• Date of the hatch (what is the natural day length at the bodyweight targeted when light stimulation will
take place for onset of lay?)
• Growth of the flock
• Past records of performance obtained in this rearing unit
• Avoid any unwanted external lights in the dark house. It can affect the lighting program and efficiency
and induce feather pecking.
 LIGHTING PROGRAMME DURING THE FIRST WEEKS OF THE REARING

PERIOD
In order to encourage skeletal development and growth, a slow step-down lighting programme is advised for all
housing conditions.
The decrease in artificial light duration during the day is then adjusted according to the housing type. For an open
house system (and above 20° Latitude), determine the natural light day length that the birds will encounter before 16
weeks of age. This will then help determine the maximum day length the flock will be given and help avoid an
unwanted early light stimulation before the flock has matured sufficiently. Early light stimulation will be promoted by
a natural increase in day length during rearing.
In dark rearing houses (and when allowed by the local regulation), it is possible to use an intermittent lighting
programme during the first two weeks of age. It allows synchronisation of the chicks’ behaviour for; eating, drinking
and resting. It can have a beneficial effect on the weakest chicks which are stimulated by the stronger ones and
improves the flock uniformity. After two weeks, switch to a regular step down lighting programme.

• 2 hours darkness • 2 hours darkness
• 4 hours light • 8 hours light
• 2 hours darkness • 6 hours darkness

LIGHTING PROGRAMME
 LIGHTING PROGRAMME FROM 8 WEEKS OF AGE TILL 2-5% OF PRODUCTION
In order to control sexual maturity and to avoid early sexual maturity at an inadequate and immature bodyweight, it
is important to avoid every day any increase in light duration (due to a natural increase in day length) during this
period.
According to the season in a dark house system a stable day length can be used between 10 weeks of age and 2-
5% of production. It will help to avoid a sexual maturity at a too early age. The light duration during this period can
also be adapted according to the growth of the pullets (10, 11 or 12 hours could be used when growth is slow).
In an open house system, the most difficult system for controlling sexual maturity, the natural day length at which the
pullets will be exposed to at 19 weeks of age will determine the light duration at the plateau to avoid any increase of
light duration before 19 weeks of age.
 INCREASING DAY LENGTH TO STIMULATE EGG PRODUCTION

After the appearance of the first eggs, the increase of artificial light duration should be adjusted according to the
production level. An increase of light duration of 30 minutes or 1 hour per week is suggested.
 LIGHTING PROGRAMME DURING PRODUCTION

Never decrease the artificial light duration during the production period as this can lead to an early decline in egg
production.
Graph: Example of lighting programme in light controlled rearing and laying houses
 LIGHT INTENSITY
A higher light intensity during the brooding period will encourage growth by promoting higher levels of activity of the
flock and a higher feed intake. After 2 or 3 weeks and according to the behaviour of the chicks, the light intensity may
be reduced to match the field conditions and the light intensity the birds will be exposed to during the production
period (degree of darkness of the rearing house and the laying house).

TRANSFER
Transfer is advised around 16 to 17 weeks of age.
• Before the appearance of the 1st eggs
• After a last vaccine planned 1 week before the transfer
• After de-worming of the flock (3 days prior the transfer)
In order to minimize the stress at transfer time, it is important to:

• Rear the birds on a similar drinking system as they will encounter on transfer.
• Increase light intensity to encourage water consumption
• Maintain temperature as close as possible to the temperature experienced by the pullets at the end of
the rearing period.
LIGHTING PROGRAMME DURING THE PRODUCTION

PERIOD
The light duration after transfer should be adjusted to match the light duration experienced at the end of the rearing
period. The post transfer light duration should be at least the same length as during the rearing phase. It may be
longer according to the plan for light stimulation. As the birds remain sensitive to changes in light duration, never
decrease the day length during the entire production period.

FLOCK MANAGEMENT DURING THE PRODUCTION PERIOD

LIGHT INTENSITY MANAGEMENT DURING THE
PRODUCTION PERIOD
It is possible after the peak of lay to reduce progressively the artificial light intensity. This may limit feed wastage,
excessive activity of the birds and reduce the risk of mortality. Please take into account that light intensity should
remain well distributed all over the house.
FLOOR EGGS PREVENTION

Floor eggs is a multifactorial problem often related to management issue at the onset of lay or house and equipment
design. We have indicated herebelow some important recommandations to maintain a good nesting behaviour:
• At the start of production, it is very important to collect floor laid eggs frequently. We recommend
collecting every hour until the early afternoon. Floor eggs that are not removed become an incentive for
other hens to lay in the same place. During this period, the farm attendant should try to identify those
hens laying on the floor and place them onto the nests.
• After transfer, possibilty to block the hens in the slats area for a maximum of 3 to 5 days. In this situation,
be careful to the nest access.
• Hens should not be disturbed while laying: avoid flock inspection and feed distribution during the main
laying period
• Birds should sleep on top of the system and not on the litter
• Lighting: ensure a uniform and sufficient light in the whole house. Any darker area is favourable to a floor
laying behaviour.
• Nest:
o Sufficent numbers
o Easy access
o Comfortable floor: use material such as Astro Turf, rubber floor, litter…
o Uniform repartition within the house
o Entrance of the nest should be well lighted and the inside of the nest darker
o No draught in the nest area
o Possibilty to use a light nest to switch on 1 hour before the house light switch on. It enables the
birds which are laying earlier to find the nest.
o Place small partition at the nest entrance in order to avoid overcrowding
• Drinking and feeding systems in floor system:
o It should not be located more than 2-3 meters of the nest
o Feeding system should be located as high or low as possible (according to the system), to allow an
easy circulation of the hens. Chain feeders can be directly fixed on the slats.
• Specific case of Floor-Slats system:
o Stricly respect the proportion of 2/3 slats and 1/3 floor
o Possibility to use ladders to facilitate access to the slats
o Install the drinking and feeding system in the slats area
• Litter: depth at the onset of lay should not exceed 2-3 cm.
• Fence: when allowed by local regulation, an electric fence around the outside of the litter or slatted areas
and along the walls and partitions may be useful. It should be fixed at 5 cm from the wall and 12 cm
above the litter.

MONITORING BODYWEIGHT AND UNIFORMITY

4. MONITORING BODYWEIGHT AND UNIFORMITY
The main objective is to reach the appropriate bodyweight and uniformity targets at different stages of the bird’s
development:
• At the early stage (0 – 7 weeks: period of frame development)
• At sexual maturity with an even growth curve (a low bodyweight at sexual maturity could affect later
performances)
• At the start of lay to the peak of production (a growth of at least 300g from 5% of lay until 30 weeks
means that the bird’s needs for egg production and growth are covered)
BODYWEIGHT CONTROL
• The birds must be sample weighed weekly from the first week. During the first 4 weeks, collective weights
can be taken in batches of 5 or 10 birds using a bucket. Subsequently, the birds can be weighed
individually.
• From 26 weeks of age, weigh the birds every 2 weeks and then monthly from 35 weeks of age,
• Weigh a sufficient number of birds (around 100) cornered using lightweight screens or frames in 2 or 3
places in the house. For an accurate interpretation of the result, it is important to weigh all the birds
caught in the sample. Weights can be recorded on a weighing sheet which is available from our
technicians. It is good practice to walk the house first to stir the birds up to allow for a more realistic
sample to be penned.
• After weighing, average bodyweight and uniformity are calculated and immediately plotted on
NOVOGEN growing curve chart. The analysis of the growing curve helps to accurately adjust the feed
allowance (the quantities indicated in our feed section are only to be considered as a guideline) and
when required, to take the appropriate steps to correct the uniformity.
UNIFORMITY CONTROL
• The uniformity target is set to ensure 80 % of the body weights are in a range between + 10 and -10 %
of the flock mean body weight.
• The following factors play an important role in achieving and maintaining good uniformity:
o access to feed and water (see equipment standards)
o health status of the flock
o disease and parasitism
o quality of beak treatment
o temperature and ventilation

MANAGING MALES
5. MANAGING MALES
In modern parent stock breeders, the males represent a small share of birds but they are responsible for 50% of the
genetic value of the flock. During rearing, the target is to obtain the best uniformity and lowest mortality in order to
select the very best males before the start of production.
KEY POINTS OF MANAGING MALES

Rearing
• The standard proportion of males on arrival of the chicks is 12%
• Males can be reared together with females as long as the farm management system makes it possible to follow
the growth and uniformity recommendations. If the target is not reached, the males can be reared separately
for a more specific management.
• Ensure an excellent condition of the floor (dipper litter, soft mat in cage…)
• Respect the minimum stocking and equipment densities (see chapter 1 Flock management during the rearing
period)
• Ensure the optimum comfort temperature (see chapter 1 Flock management during the rearing period)
• Weekly monitoring of bodyweight and uniformity. A good bodyweight uniformity is related to uniform testes
development.
• If farm debeaking is done, it must be carried out in a less invasive but much more precise way than for females.
Transfer
• At transfer, select the best males according to their bodyweight and condition.
• The recommended percentage of males in production is 9-10%, with a maximum density of 8 birds/m2.
• If the males are reared separately, their percentage can be reduced to 5-6% depending on their behaviour and
up to 5% of production. Overly mature males may affect the growth of the females by reducing access to the
feeders.
• Extra males are best kept in a separated pen. From 5% egg production, males can be progressively re-
introduced when it is dark, by adding 0.5% per week in order to reach a total of 9%.
Production
• In order to select the best males, they must be weighted weekly as per the females until 30 weeks of age and
every 4 weeks afterwards.
• Controlling the males’ weight, uniformity and activity will make it possible to immediately detect if the
relationship between the males and females is correct in order to obtain a synchronism of sexual maturity:
o Heavy males usually mature too early in comparison to the females. Be careful in that situation
as they may be too aggressive.
o Light males may not be mature enough which could affect fertility
o Too many males might results in more fighting, less mating activity, disruption of social groups
and lower fertility.
• Regular control of males’ health status, cloaca and claw condition.
• Avoid stressing the flock (maintenance, vaccination…) during the males’ activity periods, which are mainly
early morning and late afternoon.
• Ensure a good comfort for the males: Litter, slats and equipment condition must be checked frequently in order
to avoid lameness in the males.

BEAK TREATMENT
6. BEAK TREATMENT
BEAK TREATMENT MONITORING
• Beak treatment is sometimes undertaken where either light intensity cannot be controlled due to the
design of the house or when other kind of challenges chronically stress out the birds. The beak treatment
procedure is performed to prevent feather pecking and cannibalism under these conditions.
• Beak treatment is a delicate operation and should only be carried-out by well-trained and experienced
operators. Poor beak treatment can affect the ability of the birds to eat and drink correctly and leads to
unevenness. Attention should be paid to local regulations regarding beak treatment and it is advisable
to seek veterinary advice to ensure the procedures are being correctly applied.
• Two different methods can be used for beak treatment. The first one consists of an infrared treatment of
the beak at day-old in the hatchery by using a specific machine. The second method can be practiced at
7-10 days by using a hot blade. With this second method and under some specific conditions, where
permitted, a second beak treatment may be undertaken at 8-10 weeks.
• Before beak treatment with hot blades (in countries where this is permitted):
o check that the birds are healthy
o do not treat the beaks when the birds are reacting to vaccinations
o add vitamin K to the drinking water (to prevent haemorrhaging)
o check that the temperature of the blades is high enough to prevent haemorrhaging, but not too high
which may risk chicks being burned.
o Proceed to a lighter debeaking for males
• To limit the effect of beak treatment with hot blades on feed consumption and water intake, it is important
to increase the water level in the drinkers and the pressure in the pipes. Ensure that the depth of the
feed in the feeders is correct.
As outlined above, in addition to the technical recommendations, any local code or regulation concerning animal
welfare should be respected.

BEAK TREATMENT
FULLY BEAKED FLOCKS MANAGEMENT
In case of fully beaked flocks, different measures are necessary to prevent the consequences on selective feed intake
and potential damage due to pecking:
• Strictly respect the feeding and drinking spaces and the stocking density standards before starting up. It
will ensure a good uniformity of the flock and avoid risks of competition and fights between the birds.
• Keep the birds calm by avoiding any stress: equipment malfunction, visitors, any sudden changes in the
management (light intensity, number of feed distributions, feed formulation…).
• Provide distractions for the birds to keep them busy: wood shaving pack, oyster shell, plastic strings…
All the toys could help to maintain a good behavior. But layers get used to the toys very quickly, they
need to be changed regularly, each week for example, otherwise, they stop playing with.
• Distribution of grit and grain on the floor can also enhance litter scratching.
• There is a strong relationship between feeding time and pecking, the shorter the feeding time the higher
the risk of pecking. Also, the feed presentation is of high importance. If the particles are too big, it will
reduce the feeding time and increase the risk of feather pecking and feed selection. If they are too fine it
will induce poor appetite.
• Be on the alert for the absence of fluff or small feathers on the floor. It can mean that the birds are eating
the feathers due to a nutrient deficiency in fibre source and it can easily turn into feather pecking. It can
be confirmed by the presence of feather in the intestine. It is sometimes possible to reduce the level of
feather pecking by increasing the fibre content of the feed, particularly insoluble fibres. It is also possible
to add alfalfa or straw on the floor to provide additional fibre for the bird.
• Feed has to be well balanced in energy, amino acid, nutrient, fibre… Any deficiency in the feed can
induce feather pecking.
• Placing some gas concrete blocks in the house as they can help to smoothen the sharp end of the beak
and thereby prevent pecking and selective feed intake.
• It is important to maintain a suitable climate (ventilation, temperature). Hens that feel uncomfortable are
inclined to start feather pecking.
• Special attention has to be given to the lighting. Light intensity and duration are important for preventing
pecking. It is sometimes possible to reduce pecking by dimming or colouring the lights. In dark house, it
is important to avoid any unwanted light source from outside during the night period.
• In production, it is recommended to dim the light a few days after the adaptation in the production house
and to keep the nest in a dark area.
• Respect the health program and avoid parasitic proliferation.

CARE OF HATCHING EGGS ON FARM

7. CARE OF HATCHING EGGS ON FARM
The aim is to protect embryo liveability which leads to improved hatchability and chick quality. The eggs must not be
incubated before 24 weeks of age, and a minimum egg weight of 51 - 52g should be ensured.
The egg at oviposition contains an embryo of 30 000 to 60 000 cells which must be preserved. With high quality care,
the fertile egg will produce a healthy chick, whereas careless management will greatly affect hatchability and chick
quality.
EGG HANDLING
Maintaining the embryo viability is the main priority from oviposition to storage in the hatchery. The main risk for the
embryo comes from bacterial contamination immediately after the egg has been laid. As it cools down, the egg
content retracts and air enters through pores in the eggshell. If the environment (litter, nest floor) is dirty, bacteria will
invade the shell and they will be difficult to eliminate.
Dirty nests and floor eggs are often the main reason for eggs exploding in the setters and for chick contamination by
Pseudomonas and Aspergillus. The nests must therefore be maintained clean at all times. They should also be
equipped with a closing or ejection system to avoid nest occupation and staining at night.
Depending on ambient temperatures, the temperature in the nests may reach 30°C, as the hens produce heat and
the litter acts as an insulating material. If eggs are left for too long in these conditions, the embryo starts to develop
and becomes more sensitive to subsequent environmental change. This becomes more acute as the flock ages.
Egg should be cooled down uniformly and gradually to ensure embryo viability. Several factors are involved in the
egg-cooling rate and are important to consider: egg collection frequency and the nest type (Manual or automatic).
Eggs must be collected at least 4 times a day in temperate climates and more often in cold or hot climates. They
should be collected using either new carton trays or previously washed and disinfected plastic or setter trays.
The incidence of hair cracks resulting from large numbers of eggs in the nest or over supply of eggs on the
transportation belt should also be taken into consideration.
 Rules of Thumb to maintain the egg quality after Oviposition:

• An egg is a living organism and should be handled with care
• The integrity of the hatching egg must be preserved at all times
• Ensure careful handling to protect the eggshell and the content
• Avoid hair cracks by using suitable plastic or new carton egg trays
• Collect the eggs at least 4 times a day
• Nest hygiene must be irreproachable at all times to avoid contamination
• Floor eggs must be managed separately to avoid cross contamination with nest eggs
• In the collection room:
o Ensure uniform cooling with sufficient airflow
o Maintain the temperature around the egg at around 20°C (Range 18-20°C)
15

EGG DISINFECTION
Hatching eggs must be disinfected as soon as possible after oviposition during the cooling period. Various methods
are available (see table below).
Important points for proper fumigation:
• disinfect as quickly as possible once the eggs have been laid, when they are still warm
• fumigate at a temperature of 24°C, with 80% relative humidity
• use 40 ml of 30% formalin solution + 20 g of potassium permanganate, or 10 g of formalin powder, for
each m3 of space
• fumigate for 20 minutes, followed by thorough ventilation of the fumigation chamber
The traditional method is formalin. Other methods have been developed recently such as hydrogen peroxide,
quaternary ammonium compounds, chlorine, UV rays, ozone, or dipping in a disinfectant solution. Always follow the
manufacturer’s instructions specific to the treatment applied.

EGG STORAGE
The eggs must cool down gradually to reach the physiological zero (26-27°C), the temperature at which embryo
development will stop. This temperature must be reached within 6 to 8 hours, the eggs can then be placed in a cool
storage room.
Please note there can be a risk of condensation on the shell as eggs warm up rapidly following storage at low
temperatures. This must be avoided as it may cause egg contamination.
Air conditioning is strongly recommended in the egg storage room if the temperature is likely to exceed 22°C in
summer.
 Egg storage parameters according to storage duration

Depending on how long the eggs will be stored for, the temperature and humidity must be adapted.

WATER MANAGEMENT
8. WATER MANAGEMENT
Water is the first and most important requirement for poultry, it drinks around 1.8 times more than it eats. Therefore,
water management and quality is a priority to ensure optimal flock performances.
WATER MANAGEMENT DURING THE REARING PERIOD

Table: Water management recommendations
Period Advice
• Check the quality of the drinking water and the pipelines.
• Clean and rinse the water pipelines.
Before start up
• Make sure that the water temperature is around 20 to 25ºC.
• Check the nipples.
• Provide unlimited water.
• Keep the water pressure as low as possible. It will help the chicks to find the water
After start up
• Adjust the height of the drinkers according to the chick size and growth. The chicks
must be able to drink without difficulties.
WATER QUANTITY
The ratio water/feed is generally mentioned as being close to 2.0, but in reality it depends more on the environmental
temperature. In a hot temperature climate, this ratio increases as the birds will drink more and eat less. In this
condition, it is recommended to supply cool water to the birds. Water temperature above 20 ºC should be avoided.
Water consumption is an important indicator to follow. Therefore, it is recommended to install a water meter on the
water line. This equipment is inexpensive and easy to install. A low consumption can indicate a shortage of water
supply or a sanitary problem on the flock. Waste of water can also be detected thanks to the water meter.
The below table gives some indication on water consumption according to the environmental temperature (source:
ITAVI, 2012).

WATER QUALITY
• A water sample for analysis should be taken at the entry point of the house to check the quality of the
water supply, and at the end of the system to check the efficiency of the disinfection system.
• Sample once or twice a year. More samplings should be performed especially when using a local water
supply (surface well, deep well, etc…)
• Clean the pipe system during the sanitary break between flocks.
• Clean drinkers on a regular basis

NUTRITION
9. NUTRITION
Some important points :
• All NOVOGEN recommendations are made with a quality protein. That means with a good availability
and digestibility of Amino Acids (A.A.). Any quality degradation (see raw materials chapter in the Novogen
Nutritition Guide) must result in a proportional decrease in the A.A. matrix value in order to avoid any
deficiency that would limit the genetic potential of the animals.
• Any anti-nutritional factors that may alter the bioavailability of A.A. must be controlled, taken into account
in terms of risk and managed accordingly.
• There are many methods of defining available phosphorus, in particular because of the basic reference
which may be different (monocalcium, anhydrous dicalcium, monosodium...). It is therefore necessary to
adjust locally according to the field results.
• Chlorine level is more important to follow in alternative systems (you should be more strict). The
maximum recommendation is in case of good droppings quality. If the droppings are too wet, you must
decrease this maximum (in some case, until the minimum of sodium).
• These recommendations are given for an average temperature in husbandry between 20 and 22°C, an
optimal breeding and material.
• It is recommended, whenever possible, to formulate feeds in A.A-ratios, on the basis of lysine in order to
avoid any imbalance (causing a greater need and losses due mainly to competition between A.A.).
Pullets Laying hens
Dig. Lysine 100 100
Dig. Methionine 48 / 50 48 / 54
Dig. Methionine+Cystine 76 / 80 80 / 86
Dig. Tryptophan 19 / 20 20 / 22
Dig. Threonine 68 / 74 66 / 74
These ratios are indicated by ranges, they are adjusted according to the observed field performances (typically
feather, egg weight, etc.):
• Attention to the cumulative potential enzymatic valuations on A.A., protein and energy (see chapter
enzymes in NOVOGEN nutrition guide).
• In comparison to cage system, it is recommended to increase energy level by 50 Kcal in all other systems.
A minimum total fiber level is recommended for all their positive effects on the digestion and behaviour of the
animals. The minimum level at 4.0% should be increase according to birds behavior. Increase at least to 0.5% or
1% if you begin to see any signs of aggression between birds.
 LIVER PROTECTOR
Increased performances enhance the use of hepato-protectors in regular cure, usually every 5 or 6 weeks.
These special premixes are rich in elements helping to detoxify the liver as: choline, betaine, sorbitol, group B
vitamins, and sometimes also some plant extracts. The goal is to improve the performance of this key and essential
organ which is enormously stressed in the laying hen. The efficacy of the hepato-protector is optimal when used in
preventive mode, before the onset of the first clinical signs in the farm. Their use can start from 25 to 30 weeks of
age in order to preserve the capacities of laying at the end of production. This investment is almost systematically
profitable over the long term.

HEALTH PROGRAMME
10. HEALTH PROGRAMME
It is impossible to devise a health programme to adequately suit all geographic areas. For this reason, it is strongly
recommended to consult a local specialist to establish a prevention programme adapted to the region.
This guide limits its comments to the description of some rules for the use of vaccines and other treatments. To be
successful, respecting these rules is as important as choosing the right products:
• Staff should be properly trained to carry out veterinary operations. It is useful to create a Standard
Operating Procedure Manual, that describes in full details the way to perform each vaccination or
treatment.
• All the necessary equipment (sprayers, syringes, etc.) must be correctly maintained, and checked before
each use.
• Each operation should be planned and supervised by a technically competent person.
• Vaccines and treatments should be stored in appropriate conditions, in suitable quantities considering
the requirements and supply time.
• Report carefully in the flock records the details of all operations: date, time, vaccine batch number, route,
etc.
• Finally, it is useful to have the help of a laboratory in order to anticipate health problems ahead of time
and to assess the efficiency of the :
o control of disinfection, water and feed quality
o serological monitoring
o post mortem examination, routine parasite checks
VACCINATION
The vaccination programme has to be defined and regularly updated with a local veterinarian.
• Vaccine rules:
o Only vaccinate healthy flock
o Always check the conformity of the vaccines with the vaccination programme. In case of doubt,
immediately contact your local veterinarian.
o Keep records of vaccine serial numbers and expiry dates
o Use clean and specific vaccination equipment

LITTER
11. LITTER
LITTER QUALITY
Depending on the system, litter can be used to cover the floor in rearing. The main materials used for litter are
chopped straw (wheat, barley…) and wood shaving. It is recommended to use wood shaving coming from non treated
wood. Depending on the local availabilities, other material like rice hull and cellulose pellet can also be used. The
choice of the litter is an important compenent on the success of rearing by ensuring a confortable environment while
avoiding potential diease conditions. Moreover, litter is used by birds for dust bathing, foraging and scratching, which
help reduce feather picking.
Photo: Wood shaving litter in rearing
Different qualities must be taken into account for the choice of the litter:
• Thermal insulation from the cold coming from the ground. It depends of the litter material and depth. It is
very important during the first week, as long as the chicks are poikilotherm.
• Abosrption of humidity from manure and birds breath. It is particulary important in cold and wet weather
when ventilation is low.
• Low level of dust to avoid respiratory disease.
• Safe for the chicks by avoiding being a source of contamination (virus, bacteria, mould).
• Comfortable and not harmful for the chicks
Ensure the shed is fully warmed before distributing the litter. If the gap of temperature between the floor and the room
is too important, ie the floor is not warm enough, litter will become stick and wet from below.
LITTER MANAGEMENT
In order to maintain an optimal litter quality all along the flock:
• Keep under control litter humidity
• Avoid any leaking or spillage from water system (nipples, bell drinkers…).
• Floor system:
o In rearing, litter depth should be 5 cm high
o Additional fresh litter can be distributed on top of the existing litter to keep low moisture content
• Aviary system:
o 2 cm of litter is sufficient.
o In production, excess of litter should be frequently removed to avoid the floor area to be too
confortable as it could induce some floor laid eggs. It also allow to reduce dust content.
32
GENERAL FARM RULES

12. GENERAL FARM RULES
Ideally, the best rule of management is to have one age and one breed per site to ensure the "all-in, all-out" principle
is followed at all times.
The choice of the site for the farm, including the layout of the houses, must prioritise the elimination of all possible
sources of contamination. Biosecurity protection is reinforced by hygiene controls.
A changing room should be made available at the entrance of the site. It must be used by everybody entering the
farm (incorporating both a shower and a change of clothes).
When the old flock is removed and before the arrival of the new flock, all houses and equipment must be
thoroughly cleaned and disinfected according to strict procedures and protocols. This should be followed by a rest
period of at least 10 days.
33
CLEANING AND DISINFECTION OF POULTRY HOUSES

13. CLEANING AND DISINFECTION OF POULTRY HOUSES
Between each flock, cleaning and disinfection of the houses, their annexes, surroundings and access ways are
essential to ensure the optimal health conditions required for the incoming flock to maximise its profitability.
OPERATIONS PRIOR TO CLEANING

• Water tank, pipes and nipples:
o Empty the complete water system.
o Clean and de-scale the complete system with an acid solution and leave for 6 hours to soak.
o Rinse twice with clean water.
• All the equipment (nests, feeders, drinkers etc.) are removed and stored on a concrete area.
• The entire ventilation system (air inlets and outlets, fans, heating and ventilation ducts if they are present)
and individual radiant or pancake type brooders are brushed and vacuum cleaned.
• Litter is removed.
WASHING
When washing, ensure local regulations regarding wash down water are observed. As a rule, always ensure that the
dirty water is directed towards a pit or suitable internal drain and does not run outside to the house surroundings or
access roads and pathways.
 House
• Soak and remove the remaining organic matter
• Apply a bactericidal and fat removing detergent using an appliance capable of dealing with foam
products.
• Some hours after soaking, wash with a high pressure washer (>50kg/cm²) or with hot water, in the
following order:
o Internal roof surfaces, from the top downwards.
o Walls, from the top downwards.
o Finally, pits and concrete floors.
 Equipment
• Nests, drinkers and feeding equipment:
o Soak and remove all organic matter.
o Apply a bactericidal and fat removing detergent using an appliance capable of dealing with foam
products.
o Ensure every piece of equipment gets a thorough wash, followed by rinsing.
o Prior to the final rinsing, immerse the removable parts of the nests (perches and nest box bottoms)
for 24 hours in a disinfectant solution.
o Dry on a clean disinfected concrete area (different to that used for washing).
34

PLACING EQUIPMENT BACK INTO THE HOUSE
The vehicles used for this operation must have been carefully washed and sprayed with disinfectant.
DISINFECTION
• Water pipes
o Prepare a highly concentrated chlorine solution (200 ppm) in the water tank.
o Open the tank to fill the pipes with this solution and leave for 24 hours. Afterwards, drain the water
circuit. Do not forget to seal the water tank to protect it from dust.
• House
o House and equipment disinfection is achieved using a homologous bactericidal, virucidal and
fungicidal disinfectant, applied with a hand held or low pressure sprayer or a foam-producing
machine.
o The list of homologous approved disinfectants may vary from one country to another. We
recommend that you consult the relevant local Authorities for a list of approved disinfectants and the
required concentrations when used for poultry applications.
• Feed Storage Silos
o Scrape, brush wash and after drying, fumigate using fungicidal candles following the manufacturer’s
guidelines.
• Heating and ventilation ducts (if they are present)
o Disinfection using fungicidal, virucidal and bactericidal candles following manufacturer’s guidelines.
• House surroundings and road and path access ways.
o Spread a disinfecting product, such as:
 caustic soda (50 to 100 kg/1000 m2).
 or quicklime (400 kg/1000 m2).
SANITARY PRECAUTIONS
Place clean boots and overalls in the changing room. Replenish footbaths with an appropriate disinfectant.
ASSESSING DISINFECTION EFFECTIVENESS

• Visual examination
o Check for dirt stains in the house and on the equipment.
• Bacteriological analysis
o Contact plates or swabs are applied to equipment and to different places in the house. These are
rapidly forwarded to a laboratory for bacteriological assessment following an agreed protocol with
the laboratory.
RODENT CONTROL
Rodents may be vectors of numerous bacterial diseases such as salmonellosis.
Rodent control is often based on the use of toxic baits which generally contain anticoagulants. These are left in places
frequented by the rodents following a site risk assessment. A poorly prepared rodent control programme may give
variable or poor results. We therefore advise using a specialised rodent control service.
35

RESTING PERIOD
This starts only when all the above operations have been achieved and lasts for at least 10 days, in order for the
house to dry properly.
BEFORE THE NEW FLOCK ARRIVES

• 3 days before the new flock arrives, a residual insecticide is sprayed on all surfaces.
• Fresh litter is placed (never use mouldy material) and its surface sprayed with a larvicidal insecticide.
• Equipment is prepared in the brooding area.
• 24 hours before the new flock arrives, the final disinfection is performed by fogging.
• To be careful with disinfection of vehicles coming to the farm
