Embodiment Construction

[0011] specific implementation plan

[0012] The bacterial strain Bacillus subtilis CICC10071 used in the present invention was purchased from China Industrial Microorganism Culture Collection and Management Center.

[0013] Weigh 10 g of peptone, 10 g of beef extract, 10 g of glucose, and 5 g of sodium chloride, and add water to the volume to 1000 ml to obtain the Bacillus subtilis seed liquid culture medium. Take 100ml of seed solution and culture it in a 500ml Erlenmeyer flask, sterilize at 121°C for 20 minutes, cool to 30°C, inoculate Bacillus subtilis, and cultivate on a shaker at 160rpm and 30°C for 22 hours to obtain Bacillus subtilis seed solution.

[0014] Crush peanut meal and pass through a 40-mesh sieve to obtain peanut meal powder. Weigh a certain mass of peanut meal powder, add 20 times the mass of 1% glucose solution, stir evenly, sterilize at 121°C for 20 minutes, and cool down to 30°C. ℃, inoculate Bacillus subtilis seed solution with 8% inoculum amount, ferm...

Abstract

The invention belongs to the technical field of feed additives, and particularly relates to a preparation method of an egg-chicken feed additive.The method comprises the steps that peanut meal and a glucose solution are mixed and stirred to be uniform, sterilization is conducted, and bacillus subtilis is inoculated for fermentation; after fermentation is completed, boiling and cooling are conducted, and a peanut meal fermented liquid is obtained; soybean sprouts are mixed with the peanut meal fermented liquid, grinding is conducted, and a mixed slurry is obtained; the mixed slurry is hydrolyzed and then filtered, filtrate is obtained, the filtrate is concentrated and spray-dried, and dry powder is obtained; the dry powder, feed-grade fat powder, feed-grade bile acid and carrot meal are mixed to be uniform, and the finished product is obtained.The egg-chicken feed additive prepared through the method contains nutriments such as gamma-aminobutyric acid, small peptides and carotene and can effectively prevent and treat a heat stress disease of egg chickens and can improve the quality of eggs when the egg-chicken feed additive is added to daily rations of the egg chickens according to an appropriate proportion.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a method for preparing a feed additive for laying hens. Background technique [0002] Heat stress in laying hens is heat stroke, which is very easy to occur in summer when the temperature is high. Once it occurs, it will cause certain deaths, resulting in a decrease in egg production rate, deterioration of eggshell quality, and large economic losses. How to overcome the troubles caused by high temperature, minimize unfavorable factors, ensure the normal production of laying hens, and strive to reduce or avoid unnecessary losses is an important problem that laying hen farmers need to solve. Adding some chemical drugs in the feed of laying hens can have a certain therapeutic effect, but the chemical drugs have toxic side effects and will remain in the eggs and affect human health. If the green feed additive with anti-heat stress effect is added to the feed of la...
