Compound feed for egg-laying duck 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: 238-311kg of wheat, 135-165kg of barley, 124.25kg of wheat middling, 100-130kg of rice bran, 0-44kg of rice bran meal, 30kg of cotton seed meal, 30kg of rapeseed meal, 15-18kg of corn protein powder, 85-100kg of American DDGS (distillers dried grains with soluble), 35-43kg of soybean meal, 2-12kg of soybean oil, 0.8kg of methionine, 0.65kg of threonine, 3.6kg of lysine, 70kg of rock flour, 10kg 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, 0.1kg of Chang Lexin, 3kg of humic acid, 0.4kg of complex enzyme 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, reducesdrug residue in an animal product and pollution to the environment and enhances safety of the feed, 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 ducks and a preparation method thereof. Background technique [0002] In the prior art, the compound feed for laying ducks generally contains the following substances (calculated per 1000 kilograms): 470-490 kilograms of corn, 50-70 kilograms of American DDGS, 130-150 kilograms of soybean meal, 100-120 kilograms of rice bran, and 50 kilograms of rice bran meal. ~70 kg, 8~10 kg of secondary powder, 20~30 kg of rapeseed meal, 20~30 kg of cottonseed meal, 20 kg of imported fish meal, 70 kg of stone powder, 12 kg of calcium hydrogen phosphate, 10 kg of zeolite powder, 10 kg of shell powder, Lysine (70%) 0.5 kg, methionine (98%) 0.8 kg, threonine (98%) 0.15 kg, laying duck trace elements 1 kg, choline (60%) 1 kg, laying duck multidimensional 0.20 kg, 0.2 kg of bacillus titanium zinc, 3 kg of salt, 0.12 kg of Jialisu red and 1.5 kg of golden chrysanthemum. [0003] However, there are following problems in...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problem that the existing compound feed for laying ducks uses chemically synthesized pigments plus Lisu red and golden chrysanthemum yellow, which are easy to remain in eggs after being absorbed by laying ducks, which is harmful to human health. Low, most of it is discharged into the environment, which not only causes the waste of phosphorus resources but also pollutes the environment. It provides a kind of chemical-synthesized pigment, which has high egg yellowness, and can improve the laying rate of laying ducks and enhance feed safety. The compound feed for laying ducks and its preparation method which realize the minimum feed cost input and the maximum benefit
