Abstract

The invention belongs to the technical field of feed additives and particularly relates to a preparation method of a laying duck feed additive. The preparation method comprises the following steps: after uniformly mixing rice flour and peanut meal, adding water and sterilizing; cooling to 32-35 DEG C, and inoculating purple monascus and boiling to obtain a sterilized fermentation solution; after uniformly mixing sprouted unpolished rice flour and the sterilized fermentation solution, carrying out enzymolysis; then boiling and filtering to obtain filtrate; concentrating, spraying and drying the filtrate to obtain fine dry powder; and uniformly mixing the fine dry powder with feed-grade bile acid to obtain a finished product. The laying duck feed additive prepared by the method contains rich nutritional and functional substances including gamma-amino butyric acid, arginine, monascus pigment and bile acid and the like; the laying duck feed additive is added into laying duck daily ration in a proper ratio and can be used for effectively preventing heat stress diseases of the ducks; and meanwhile, the quality of the laying ducks can also be improved.

Description

A kind of preparation method of feed additive for egg-laying ducks

Technical field

The invention belongs to field of feed additive technology, be specifically related to the preparation method of a kind of feed additive for egg-laying ducks.

Background technology

Egg duck health is covered with thick close feather, can efficiently reduce body heat abstraction, but its skin needs to be completed by respiratory system without sweat gland, evaporative heat loss, adds that egg duck metabolism is vigorous, fever, and these are the formation of the cold-resistant habit that To Be Protected from Heat of egg duck.High-density rearing's mode in modern intensiveization house, make egg duck can not be subject to heat stress with water source regulation body temperature, especially high temperature area or season, high temperature causes serious physiological responses to heat stress can to egg duck, show as clinically searching for food minimizing, ight soil cross dilute egg production reduce, eggshell dirty, there is also the phenomena of mortality time serious.Gabanergic strengthens antioxygenic property and the immune performance of laying ducks, alleviates the harm of heat stress, and arginine can also alleviate the negative effect that high-temperature hot stress be brought to a certain extent.

Summary of the invention

It is an object of the invention to provide the preparation method of a kind of feed additive for egg-laying ducks that can prevent and treat egg duck heat stress disease, raising duck's egg quality.

The object of the present invention is achieved like this:

Rice is pulverized to obtain rice meal, peanut meal is pulverized to obtain peanut meal powder, weighs rice meal and peanut meal powder respectively according to the ratio of mass ratio 1:5, mix to obtain mixed powder, add the clear water of 25-30 times of quality of mixed powder, stirring, under the conditions of 121 DEG C, sterilizing 15-20 minute, cools to 32-35 DEG C, purple red colouring agent for food, also used as a Chinese medicine seed liquor is inoculated by the inoculum concentration of 5-10%, shaking table top fermentation 35-40 hour of 160-180rpm, 32-35 DEG C, then boil 10 minutes, be cooled to 40 DEG C sterilization fermentation liquid.

Sprouted unpolished rice is pulverized to obtain germination brown rice powder, weigh the germination brown rice powder of certain mass, add the sterilization fermentation liquid of 25-30 times of quality, mix, pH is adjusted to 4.5-5.0, maintain 4-7 hour under the conditions of 37-40 DEG C, it is warmed up to 45-55 DEG C again, keep 1-2 hour, filter to get filtrate after then boiling 10-15 minute, filtrate is the most concentrated, be spray-dried after obtain exquisite dry powder.

Get product after exquisite dry powder and feed grade bile acid are mixed according to the ratio of mass ratio 50:1.

Present invention additionally comprises following feature:

The preparation method of described purple red colouring agent for food, also used as a Chinese medicine seed liquor is: weighs peptone 15g, maltose 50g, potassium dihydrogen phosphate 1g, magnesium sulfate 0.5g, adds water and be settled to 1000ml, obtains purple red colouring agent for food, also used as a Chinese medicine seed liquor culture medium.Take 100ml seed liquor to cultivate based in 500ml triangular flask, 121 DEG C of sterilizings 20 minutes, be cooled to 32-35 DEG C, inoculate purple red colouring agent for food, also used as a Chinese medicine, the shaking table of 160-180rpm, 32-35 DEG C is cultivated 20-24 hour.

The feed additive for egg-laying ducks made by the inventive method, rich in nutrition and effect materials such as GABA, the arginine of peanut protein degraded generation, the monascorubin of purple red colouring agent for food, also used as a Chinese medicine metabolism product and bile acids that sprouted unpolished rice hydrolysis produces, add in egg duck daily ration by proper proportion, can effectively prevent and treat duck heat stress sick, the quality of duck's egg can also be improved simultaneously.

Specific embodiments
