Laying hen feed for producing high-calcium and high-zinc nutrient eggs and preparation method of laying hen feed

Abstract

The invention provides a laying hen feed for producing high-calcium and high-zinc nutrient eggs and a preparation method of the laying hen feed and relates to the technical field of poultry raising. The laying hen feed is prepared from the following raw materials in parts by weight: 50-65 parts of corns, 20-30 parts of soybean meal, 20-30 parts of a peanut cake, 20-30 parts of rapeseed meal, 15-25parts of wheat bran, 8-15 parts of shell powder, 4-10 parts of fish bone meal, 4-10 parts of fructus lycii powder, 1-5 parts of garlic bulb powder, 2-6 parts of lotus leaf powder, 1-5 parts of rhizoma dioscoreae powder, 0.08-0.16 part of vitamin A, 0.1-0.15 part of vitamin D3, 0.06-0.12 part of vitamin B1, 0.12-0.18 part of vitamin B2, 0.05-0.1 part of vitamin K, 0.1-0.5 part of methionine, 0.4-1.2 parts of lysine, 0.1-0.5 part of threonine, 0.5-1.5 parts of zinc gluconate, 0.3-1 part of calcium iodate, 0.5-1.2 parts of sodium chloride and 0.2-0.6 part of a bacillus subtilis preparation. Thelaying hen feed provided by the invention can remarkably increases the contents of trace elements including calcium and zinc in the eggs, is balanced in nutrition, can increase the laying rate of a laying hen and is simple in preparation technology.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular 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 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...

AI Technical Summary

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
