Preparation method of feed for egg-laying hens at early egg laying period

Abstract

The invention relates to a preparation method of a feed for egg-laying hens at an early egg laying period. The preparation method comprises the following 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 DDGS, 0.5-1 part of vegetable oil, 1-1.5 parts of conch meal, 0.3-0.6 part of table salt, 0.1-0.5 part of complex vitamins, 0.1-0.3 part of trace elements, 0.2-0.5 part of gamma-aminobutyric acid, and 4-6 parts of traditional Chinese medicine microecology microcapsules, crushing the corn, the bran and the soybean meal, then adding remaining raw materials, and performing high-temperature granulation and cooling so as to prepare a granulated feed. The feed prepared by the preparation method disclosed by the invention has the efficacies of increasing the quantity of beneficial microflora in intestinal tracts, improving immune functions, strengthening the stress resistance and the disease resistance of chicken bodies, increasing egg laying yield, increasing rate of qualified eggs and the like. The feed is simple in preparation method, convenient to use, and free from residues. The preparation method disclosed by the invention has the beneficial effects that aspartic acid, glutamic acid and leucine in the eggs are increased, of which the quantities are 2-3 times of those of market eggs, tumor necrosis factors are reduced by 41.26%, epidermal growth factors are reduced by 18.59%, the egg laying rate is increased by 4.68% and 5.72%, the ratio of the feed to the eggs is reduced by 5.28% and 7.56%, and the soft egg and broken egg rate is reduced by 32.17% and 22.46%, so that the feed is saved, the cost is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a method for preparing feed for laying hens in the early 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. The pre-laying stage is the most important part of the growth stage of laying hens. If this stage is not well controlled , It will seriously affect the egg production and egg quality of laying hens, the uniformity when entering the cage and the total weight of eggs. In order to increase the growth rate, it is very common to use high-energy methods in the preparation of feed, but it also brings some problems to laying hens, such as indigestion, metabolic dysfunction, etc., which reduces feed remuneration and causes laying hens to die. Layer hen farming produces huge economic losses. ...
