Dairy Farm Management : Dairy farming is the management of animals for production of milk and its
products meant for human consumption.
Animals suffer from several bacterial diseases. For example, cattle suffer from anthrax, mastitis,
pneumonia, etc.
Note :
Diethylstilbestrol (DES) also known as stilbestrol is a non steroidal estrogen against which is no longer
used due to its side effects. In the past it was used for a variety of indications including pregnancy
support etc.

Bacterial Diseases :
1. Anthrax : Anthrax is caused by the bacterium, Bacillus anthracis. This disease is contagious and
affects cattle, buffaloes, horse, sheep and goats; it can also spread to human beings. In animals,
anthrax spreads through contaminated food, water and pastures.
Prevention and control : General measures for prevention of infectious diseases should be followed.
The healthy animals should be vaccinated. Animals that have come in contact with diseased animals
should be given anthrax antiserum to protect them from the disease.
2. Mastitis : It is the inflammation of the udder that often occurs in dry cows due to infection of bacterium
"Cornybacterium pyogenes".
Viral Diseases :
Rinderpest or Cattle plague : This disease is caused by a virus and is highly contagious. The virus is
present in all the fluids and secretions of the body of the diseased animal. The disease spreads rapidly by
direct contact with infected animals, through contaminated food, water, workers or their clothes and by flies.
Prevention : All the measures for prevention of infectious diseases should be implemented. It is highly
desirable to vaccinate the animals against rinderpest. In 1954, a massive vaccination programme was initiated
in India. This project has been highly successful, and rinderpest is no longer a dreaded disease.
Poultry farm management : Poultry is the class of domesticated fowl (birds) used for food and for their
eggs. They typically include chicken and ducks, and sometimes turkey and geese. The word poultry is often
used to refer to the meat of only these birds, but in a more general sense it may refer to the meat of other
birds too.
As in dairy farming, selection of disease free and suitable breeds, proper and safe farm conditions, proper
feed and water, hygiene and health-care are important components of poultry farm management.
1. Poultry birds exclusively grown for meat are called broilers (e.g., Plymouth rock).
2. Layers are female fowls raised for egg production (e.g., White leghorn).
3. Bird flu is an avian influenza which can also attack human beings. It was caused by (H5N1) influenza
virus in 2003 (Thailand).
4. Culling-Selective removal and slaughter of infected birds.
Infected birds pass on virus through their saliva, nasal secretions and faeces. In 1918, it attacked
human beings and killed about 50 million humans. The reservoir of bird flu seems to be migratory birds.
The virus attacks and kills monocytes. The raw meat and eggs may contain virus. Once an outbreak is
detected, the infected chickens are culled to prevent spread of the disease.

ANIMAL BREEDING
Breeding of animals is an important aspect of animal husbandry. Animal breeding aims at increasing the yield
of animals and improving the desirable qualities of the produce.

3. Karan Fries : The breed has its origin at the National Dairy Research Institute Karnal and
is produced by crossing between Tharparkar and Holstein-Friesian.
4. Frieswal : Crossbreed of Holstein-Friesian and Sahiwal cows.
(c) Interspecific hybridisation : In this method, male and female animals of two different related
species are mated. In some cases, the progeny may combine desirable features of both the
parents, and may be of considerable economic value, e.g., the mule (a cross between male donkey
and female horse)

BEE-KEEPING
Bee-keeping or apiculture is the maintenance of hives of honeybees for the production of honey. It is an
age-old cottage industry. Honey is a food of high-nutritive value and also used in the indigenous systems of
medicine. Honeybee also produces beewax, which finds many uses in industry, such as in the preparation
of cosmetics and polishes of various kinds. The increased demand of honey has led to large-scale bee-keeping
practices which has become an established income-generating industry, whether practiced on a small or on
a large scale.

Bee-keeping can be practiced at any place where there are sufficient bee pastures of some wild shrubs, fruit
orchards and cultivated crops.
There are several species of honeybees which can be reared. The most common of species found in the
wild is Apis indica in India. Beehives can be kept in one’s courtyard, on the verandah of the house or even
on the roof. Bee-keeping is not labour-intensive.
Common species of honey bees:
Bee-keeping though relatively easy does require some specialised knowledge and there are several
organisations that teach bee-keeping. The following points are important for successful bee-keeping –
(i) Knowledge of the nature and habits of bees
(ii) Selection of suitable location for keeping the beehives
(iii) Catching and hiving of swarms (group of bees)
(iv) Management of beehives during different seasons, and
(v) Handling and collection of honey and beewax. Bees are the pollinators (Entomophilly) of many of
our crop species such as sunflower, Brassica, apple, pear etc. Keeping beehives in crop fields
during flowering season increases pollination efficiency and improves the yield of honey.
Social organization (Castes) of honey bee : The nest of honey bees is known as a bee-hive. The hive
consists of 32 to 60 thousand individuals, showing a highly organized division of labour in the colony. Bees
are polymorphic, consisting of three types of individuals (Castes) viz, Queen, Drone and Worker.

From its mandibular gland, the developing queen secretes antiqueen substances or antiqueen
pheromones which inhibit the worker bees from building brood chambers and developing ovaries.
Drones are male honey bees. They develop from unfertilized eggs. The phenomenon is called arrhenotoky.
Drones and virgin queens take part in nuptial flight. After copulation, the drones are not allowed to come
back into hive.
The queen stores the sperm in her spermatheca. They are sufficient to fertilize all the eggs that are laid by her.
Females develop from fertilized eggs. Workers are sterile females. Scout bees search for food and intimate
the same to worker bees by dances – round dance for less than 75 m and tail wagging dance for
longer distances of the new food source from the hive. Prof. Karl Von Frisch decoded the language of “bee
dances” and got Nobel Prize in Medicine or Physiology for it in 1973.
Honey : Honey is a sugary syrup with nearly neutral pH of 6.8 having 17-25% water, 3.3% minerals,
abundant vitamins (B1, B6, C, D), L-fructose (Levulose = 41%), glucose (35%), sucrose (1.9%) and dextrin
(1.5%). It is tonic, laxative and sweetening agent.
It prevents infection if applied to a wound. A number of ayurvedic medicines are taken with honey.
Bees wax: Bees wax is considered primary product as it is secreted by abdominal wax glands of the
worker bees. It possesses a hardening substance from cephalic gland and a resin called propolis from
pollen grains.
Apis mellifera is commonly reared commercially in India also due to its higher yield as compared to
Apis indica.
Artificial beehive: It consists of wooden boxes having a large brood chamber placed on a wooden platform
with an opening at the bottom for the entry and exit the bees. A number of frames coated with wax sheets
having hexagonal imprints is placed inside. Each wax sheet, known as comb foundation, provides the
foundation arc for the bees to build combs on both the sides.

To start a colony in the artificial hive, a gravid (fertilized) queen is introduced into the brood chamber.
Artificial hives are placed in gardens, orchards and fields having flowering plants providing the pollen and
nectar. When sufficient honey has been stored, the combs are removed from the frames and then
centrifuged to extract the honey.

FISHERIES
Fishery is an industry devoted to the catching, processing and selling of fish, shellfish or other aquatic animals.
A large number of our population is dependent on fish, fish products or other aquatic animals such as prawn,
crab, lobster, edible oyster, etc., for food. Some of the freshwater fishes which are very common include Catla,
Rohu and common carp. Some of the popular marine fishes that are eaten include – Hilsa, Sardines, Mackerel
and Pomfrets.
“Aquaculture” involves production of useful aquatic plants and animals such as fishes, prawns, shrimps,
lobsters, crabs, molluscs (edible and pearl oysters) by the proper utilisation of small and large bodies
of water. “Pisciculture” is production of fishes.
Fish meal is a rich source of protein for cattle and poultry. It is prepared from non-edible parts of fish such
as tails, fins and bones which are discarded from factories that extract oil from fishes. Fish waste is also
used for making fertilisers and adhesives. Shark leather (shark skin) called shagreen is used in polishing
the wood and other material. Fish leather is used to make articles such as hand bags, shoes, tobacco
pouches etc. These are considered fashionable and fetch a high price in the market.
Isinglass : It is a gelatinous substance obtained from the air bladder of perch, Indian Salmon and cat
fish used in preparation of special cement and in clarification of wine and beer.
Besides serving as table food, fishes are of medicinal value. Shark liver oil and cod liver oil are
natural sources of vitamins A and D. Oil from sardines, herrings and salmon is used in the
manufacture of soaps and paints.
Fisheries have an important place in Indian economy. It provides income and employment to millions of
fishermen and farmers, particularly in the coastal states. For many, it is the only source of their livelihood. In
order to meet the increasing demands of fisheries, different techniques have been employed to increase
production. For example, through aquaculture and pisciculture we have been able to increase the production
of aquatic plants and animals, both fresh-water and marine. This has led to the development and flourishing
of the fishery industry, which has brought a lot of income to the farmers in particular and the country in general.
This enhancement of fish production is called ‘Blue Revolution’. Inland fisheries involves culturing fish in
water bodies which are land locked like lakes, ponds
Culture fishery is raising of fishes in tanks and ponds while capture fishery is a method of catching fish
without actually raising them.
Culture Fishery : In this method, pituitary hormone extract is injected into male and female breeder
fish. Two males and one female are then kept in a breeding happa, a bamboo and cloth container.
Spawning takes place in 3-6 hours. The fertilized eggs are removed and kept in hatcheries, where
they hatch in 15-18 hours. The hatchlings are kept in glass-jar hatcheries. A mouth is formed on the third
day and the young fish are now called fry. They are kept in rearing ponds for about three months, where they
grow into 4”-6” long fingerlings. The fingerlings are then released into stocking ponds where they grow to
the required size. In composite fish culture, different species of fish like catla, rohu and mrigal are cultured
together.
Types of Ponds : Three types of ponds are required for the culture of Indian major carps: nursery, rearing
and stocking ponds.
(i) Nursery Ponds : Efficient pond fish culture requires special preparation of nurseries to receive the tender
hatchlings at spawn. Small and seasonal nurseries are preferred as they facilitate effective control of the
environmental conditions. The steps adopted towards preparation of nurseries are control of predatory
fishes and weeds, There should be production of zooplanktons to serve as food for spawn and control
of algal blooms.
(ii) Rearing Ponds : The fries (sing. fry = young one of fish) are collected from the nursery ponds and
released in rearing ponds where fries develop into fingerlings.

NEET Strategies for Enhancement in Food Production 59
(iii) Stocking Ponds : The fingerlings are netted out from the rearing ponds to stocking ponds where they
change to fish. In the stocking ponds, the fishes are kept for stocking.
SERICULTURE
Sericulture is the breeding and management of insects for the production of silk. All the four varieties of
natural silk, mulberry, tassar, eri and muga, are produced in India. India ranks third among the mulberry
silk producing countries of the world.
z Silks are of two main types, mulberry silk or cultivated silk and non-mulberry silk or wild silk.
z The non-mulberry silk industry is found in Assam, Bihar, Bengal, Odisha and Madhya Pradesh. There
are three main types of this silk.
(i) Tassar (tussore, tussur) silk (kosa) is obtained from the oak-feeding larvae of the silk moth (Antheraea
roylei and A. mylitta. It is a native of India and China. Tassar cocoons are attached by a peduncle to twigs of
sal trees.
(ii) Muga silk is produced by larva of Antheraea assamensis in Assam. It is golden yellow in colour and
superior to tassar silk in gloss and other qualities. It is an excellent material for embroidery.
(iii) Eri or Arundi silk is produced by larva of Philosamia ricini and is made in Bengal, Bihar and Assam.
The eri silkworms feeds on castor leaves and is reared indoors. The cocoons are soft and white or
yellowish. The filaments are very delicate, so that the yarn is spun like cotton.
Farmers now harvest three times the silk cocoons they did ten years ago. Depending upon the number of crops of
silkworm cocoons raised per year, sericulture is univoltine, bivoltine or multivoltine.
z Rearing of mulberry silkworm : The life history of the silk moth passes through four stages, eggs, larva,
pupa and adult.

Eggs : During sericulture, the female silk moth is made to lay eggs on sheets of paper. About 300-500 eggs
are laid at a time. The eggs are kept in cold storage for about six weeks. They are then washed in water
and dried indoors.
Larva (silkworm) : In about 10 days the eggs hatch into silkworms. The larvae are fed on pieces of
mulberry leaves for 10 days. The silkworms pass through five stages. Moulting takes place after each
stage, and the larval skin is cast off. At the end of the fourth stage, the silkworm goes into a 'figure of eight'
position and secretes a cocoon around itself.
z Cocoon formation : The cocoon is formed by two pairs of glands. Liquid secretions of a proteinaceous
material called fibroin emerge from the glands called spinneret. They harden on exposure to air forming
twin filaments. A gummy substance called sericin and is secreted by the second pair of glands (spinnerets)
cements the two filaments together. Silk is a continuous filament, with a usable length of 600-900 meters.
After the cocoon is completed, the larva becomes inactive for 10-15 days, and is transformed into the pupa
or chrysalis. The pupa is killed in the cocoon by dipping it in boiling water, or by steam or hot air.
z Degumming : Silk containing sericin is called raw silk. Sericin is a gummy substance which is usually
retained till the yarn or fabric stage, because it gives protection during processing. After weaving, the silk
cloth is boiled to remove the excess of natural gum. This process is called degumming of silk. It leaves
the silk soft and lustrous and reduces its weight
z Common diseases of silkworm are pebrine by protozoan Nosema bombycis, muscardine by fungus
Spicaria and Botrytis and flacherie by virus.
