Compound feed for egg-laying chicken and preparation method thereof

Abstract

The invention discloses compound feed for an egg-laying duck and a preparation method thereof. Every 1000kg of the compound feed comprises the following materials: 336-425kg of wheat, 85-150kg of barley, 74.45-94.45kg of wheat middling, 43-100kg of rice bran, 20kg of cotton seed meal, 20kg of rapeseed meal, 15-33kg of corn protein powder, 80-120kg of American DDGS (distillers dried grains with soluble), 50-60kg of soybean meal, 11-15kg of soybean oil, 0.8kg of methionine, 0.75kg of threonine, 4.3kg of lysine, 60kg of rock flour, 20kg of shell powder, 5kg of calcium hydrophosphate powder, 3kg of salt, 1kg of egg-laying duck microelements, 0.2kg of egg-laying duck multiple vitamins, 1kg of choline, 3kg of humic acid, 0.4kg of complex enzyme, 0.1kg of Chang Lexin and 5kg of medlar. The preparation method comprises that the feed is mixed in class and finally a feed product is obtained. The compound feed disclosed by the invention contains no medical additive, reduces drug residue in an animal product and pollution to the environment, enhances safety of the feed and improves chromaticity of egg yolk and laying rate of the egg-laying duck, and minimization on cost input of the feed and maximization on benefits are realized.

Description

technical field [0001] The invention relates to a compound feed for laying hens and a preparation method thereof. Background technique [0002] In the prior art, the compound feed for laying hens generally contains the following substances (calculated per 1000 kg): 540-560 kg of corn, 50-60 kg of American DDGS, 130-150 kg of soybean meal, 8-12 kg of secondary powder, rice bran meal 20-30 kg, 20-30 kg rapeseed meal, 20-25 kg imported fish meal, 40-60 kg rice bran, 20-30 kg cottonseed meal, 12 kg calcium hydrogen phosphate, 60 kg stone powder, 20 kg shell powder, lysine (70%) 1 kg, methionine (98%) 1.1 kg, threonine (98%) 0.35 kg, layer trace elements 1 kg, choline (50%) 1 kg, layer multidimensional 0.20 kg, bacitracin zinc 0.2 kg, 3 kg of salt, 0.12 kg of jialisuhong and 1.5 kg of golden chrysanthemum. [0003] However, there are the following problems in the compound feed for laying hens in the prior art: chemically synthesized pigments Jialisu red and golden chrysanthemum...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problem of using chemically synthesized pigments such as Lithin Red and Chrysanthemum Yellow in the existing compound feed for laying hens, which are easy to remain in the eggs after being absorbed by the laying hens, which is unfavorable to human health. Low, most of it is discharged into the environment, which not only causes waste of phosphorus resources but also pollutes the environment. It provides a kind of chemical-synthesized pigments, high egg yellowness, and can improve the laying rate of laying hens and enhance feed safety. The layer hen compound feed and its preparation method which realize the minimum feed cost input and the maximum benefit
