Problems solved by technology

Although some researchers added high-dose inorganic calcium and zinc sources as feed additives to the feed, they found that the calcium and zinc elements in the edible part of the eggs did not increase, but the calcium deposition in the eggshell increased. The egg production rate of chickens is reduced, the laying cycle is shortened, and no good results have been achieved

Embodiment 1

[0038] This example prepares a feed for laying hens.

[0039] The feed preparation process is as follows: pulverize the feed base of laying hens, add water to prepare and mix evenly → microwave treatment for disinfection and sterilization → inoculate 0.2% Bacillus cereus and 160mg / kg Bacillus megaterium at high temperature at 80°C, and ferment with ventilation for 24 hours → fermentation is completed , cooled to 37°C, added 110g / kg calcium lactate, 3g / kg zinc gluconate, 0.1% glycylglutamine, 0.5% high nucleic acid yeast hydrolyzate, mixed well → bagged.

[0040] The laying hen feed base material includes: 5% of premix; 19% of soybean meal; 8% of stone powder; 63% of corn meal; and 5% of pine needle powder.

Embodiment 2

[0042] This example prepares a feed for laying hens.

[0043]The feed preparation process is as follows: pulverize the feed base of laying hens, add water to prepare and mix evenly → microwave treatment for disinfection and sterilization → inoculate 0.15% Bacillus cereus and 200 mg / kg Bacillus megaterium at high temperature at 75°C, and ventilate for 24 hours → fermentation is complete , cooled to 25°C, added 115g / kg calcium lactate, 3.5g / kg zinc gluconate, 0.08% glycyl glutamine, 0.4% high nucleic acid yeast hydrolyzate, fully mixed → bagging.

[0044] The laying hen feed base material includes: 5% of premix; 19% of soybean meal; 8% of stone powder; 63% of corn meal; and 5% of pine needle powder.

Embodiment 3

[0046] This example prepares a feed for laying hens.

[0047] The feed preparation process is as follows: pulverize the feed base of laying hens, add water to prepare and mix evenly → microwave treatment for disinfection and sterilization → inoculate 0.4% Bacillus cereus and 120 mg / kg Bacillus megaterium at high temperature at 85°C, and ventilate and ferment for 24 hours → complete the fermentation , cooled to 37°C, added 120g / kg calcium lactate, 4g / kg zinc gluconate, 0.2% glycyl glutamine, 0.3% high nucleic acid yeast hydrolyzate, mixed well → bagged.

[0048] The laying hen feed base material includes: 5% of premix; 19% of soybean meal; 8% of stone powder; 63% of corn meal; and 5% of pine needle powder.

Abstract

The invention belongs to the field of feed, and in particular relates to a laying hen feed for producing high-calcium and high-zinc nutritious eggs and a preparation method thereof. The laying hen feed contains: base material fermented product, calcium lactate, zinc gluconate, glycyl glutamine and high nucleic acid yeast hydrolyzate; Bacillus and the product after ventilated fermentation; the inoculation amount of said Bacillus cereus is 0.05-0.8% by weight, the inoculum amount of Bacillus megaterium is 0.005-0.05% by weight; the content of calcium lactate is 8-15% by weight, glucose The content of zinc acid zinc is 0.1-0.5% by weight, the content of glycyl glutamine is 0.01-0.5% by weight, and the content of high nucleic acid yeast hydrolyzate is 0.1-0.5% by weight. The laying hen feed of the invention obviously improves the laying quality of laying hens, and reduces the amount of feed to be fed, thereby improving the production benefits of laying hen breeding.

Description

technical field [0001] The invention relates to the field of feed, and more particularly, to a laying hen feed for producing high-calcium and high-zinc nutritious eggs and a preparation method thereof. Background technique [0002] Feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additives, whey powder, oil, meat and bone meal, grain, sweet sorghum and other more than ten varieties of feed materials. Feed additives are a kind of substances that are added in a small amount in livestock and poultry diets to correct nutritional deficiencies caused by the lack of dietary components or play a special role in the growth of livestock and poultry. [0003] Eggs are rich in nutrients and can be used as a carrier of various nutrients. Calcium and zinc are especially important for human health. Although some researchers added high doses of inorganic calcium and zinc sources as feed additives to the feed, they found that the calcium and zinc elemen...
