Method for preparing feed for laying hen at late period of laying

Abstract

A method for preparing feed for laying hens at a late period of laying comprises the steps of weighing the following raw materials in parts by weight: 50-58 parts of corn, 8-12 parts of bran, 20-25 parts of soybean meal, 1-3 parts of bone meal, 0.5-1 part of vegetable oil, 1-1.5 parts of shell powder, 0.3-0.6 part of salt, 0.1-0.5 part of vitamin complex, 0.3-0.6 part of microelement, 0.2-0.5 part of gama-aminobutyric acid and 4-6 parts of traditional Chinese medicine microecological microcapsule, grinding the corn, the bran and the soybean meal, then adding the remaining materials, granulating at high temperature and cooling to obtain the granulated feed. The feed has the efficacies of increasing beneficial bacteria in intestine, improving immunity, enhancing stress resistance and disease resistance of a hen body, and increasing egg yield as well as percent of pass of eggs; in addition, the preparation method is simple and convenient to use without residue. The method has the beneficial effects that aspartic acid, glutamic acid and leucine in the eggs are increased to 2-3 times of those in commercially available eggs, a tumor necrosis factor is reduced by 43.62%, an epidermal growth factor is decreased by 17.54%, a laying rate is raised by 4.86% and 7.27%, a feed-egg ratio is reduced by 7.65% and 5.82%, a rate of eggs with soft shells and shell cracks is decreased by 23.64% and 31.72%, the feed is saved, costs are reduced, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a preparation method of feed for laying hens in the later stage of laying eggs. Background technique [0002] With the rapid development of modern society and the continuous improvement of people's living standards, eggs have become an indispensable source of protein in every family's life. In order to improve the growth rate, it is very common to use high-energy, high-protein, high-copper, high-iron, and high-calcium methods in feed preparation. However, it also brings some problems to laying hens, such as indigestion and metabolic dysfunction. Feed remuneration is lost, resulting in the death of laying hens, which will cause huge economic losses to the laying hen breeding industry. [0003] Feed is extremely critical to the health of laying hens and to increase egg production. In the prior art, some feed additives have appeared in consideration of the prevention and c...
