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 embodiment prepares a kind of laying hen feed.

[0039] The feed preparation process is as follows: crush the layer feed base material, add water to prepare, mix well → microwave treatment for disinfection and sterilization → inoculate 0.2% Bacillus cereus and 160mg / kg Bacillus megaterium at 80°C, ventilate and ferment for 24 hours → complete the fermentation , cool down to 37°C, add 110g / kg calcium lactate, 3g / kg zinc gluconate, 0.1% glycyl glutamine, 0.5% high nucleic acid yeast hydrolyzate, mix thoroughly → pack into bags.

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

Embodiment 2

[0042] This embodiment prepares a kind of laying hen feed.

[0043]The feed preparation process is as follows: crush the feed base material for laying hens, add water to prepare, mix well → microwave treatment for disinfection and sterilization → inoculate 0.15% Bacillus cereus and 200mg / kg Bacillus megaterium at a high temperature of 75°C, ventilate and ferment for 24 hours → complete fermentation , cool down to 25°C, add 115g / kg calcium lactate, 3.5g / kg zinc gluconate, 0.08% glycyl glutamine, 0.4% high nucleic acid yeast hydrolyzate, mix well → pack into bags.

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

Embodiment 3

[0046] This embodiment prepares a kind of laying hen feed.

[0047] The feed preparation process is as follows: crush the layer feed base material, add water to prepare, mix well → microwave treatment for disinfection and sterilization → inoculate 0.4% Bacillus cereus and 120mg / kg Bacillus megaterium at 85°C, ventilate and ferment for 24 hours → complete fermentation , cool down to 37°C, add 120g / kg calcium lactate, 4g / kg zinc gluconate, 0.2% glycyl glutamine, 0.3% high nucleic acid yeast hydrolyzate, mix thoroughly → pack into bags.

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

Abstract

The invention belongs to the field of feed and specifically relates to laying hen feed for producing calcium-rich and zinc-rich nutritional eggs and a preparation method of the feed. The laying hen feed includes: a fermented base ingredient, calcium lactate, zinc gluconate, glycyl glutamine and a high-nucleic acid yeast hydrolysate, wherein the fermented base ingredient is a product of the base ingredients of the laying hen feed inoculated with bacillus cereus and bacillus megaterium through ventilating fermentation. The inoculation amount of the bacillus cereus is 0.05%-0.8% by weight and the inoculation amount of the bacillus megaterium is 0.005%-0.05% by weight; the content of the calcium lactate is 8%-15% by weight; the content of the zinc gluconate is 0.1%-0.5% by weight; the content of the glycyl glutamine is 0.01%-0.5% by weight; and the content of the high-nucleic acid yeast hydrolysate is 0.1%-0.5% by weight. The laying hen feed provided by the invention significantly improves the quality of the eggs laid by laying hens and reduces the feed amount for feeding the laying hens so as to increase the production benefit of raising the laying hens.

Description

technical field [0001] The invention relates to the field of feed, more specifically, to a layer 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 more than ten varieties of feed materials. Feed additives are substances that are added in small amounts in livestock and poultry diets to correct nutritional deficiencies caused by the lack of dietary ingredients or to 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 particularly important for human health. 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...
