Preparation method of feed for laying hens at egg laying middle stage

Abstract

The invention discloses a preparation method of a feed for laying hens at an egg laying middle stage. The preparation method comprises the following steps of weighing the following raw materials in parts by weight: 50-55 parts of corn, 8-10 parts of bran, 20-25 parts of soybean meal, 5-10 parts of traditional Chinese medicine micro-ecological microcapsules, 2-2.5 parts of conch meal, 1-1.5 parts of bone meal, 0.3-0.6 part of table salt, 0.5-1 part of vegetable oil, 0.1-0.5 part of composite vitamins, 0.1-0.3 part of trace elements and 0.5-0.8 part of gamma-aminobutyric acid; and crushing the corn, the bran and the soybean meal powder, adding the remaining raw materials, and performing high-temperature granulation and cooling so as to obtain the granular feeds. The feed disclosed by the invention has the efficacies of increasing the number of beneficial bacterium groups in intestinal tracts, enhancing immune functions, strengthening stress resistance of chicken bodies, strengthening the disease resistance of the chicken bodies, increasing egg production, increasing the rate of qualified eggs and the like; besides, the preparation method is simple, and the feed is convenient to use and free from residues. The feed disclosed by the invention has the beneficial effects that the feed has a good effect of repairing oviduct damage of egg laying hens, the content of aspartic acid, glutamic acid and leucine in eggs is increased and is 2-3 times of that of eggs sold in the market, the egg laying rate is increased by 5.72% and 4.68%, the feed-egg rate is reduced by 7.82% and 5.65%, and the rate of soft and broken eggs is reduced by 12.17% and 8.46%; the feeds are 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 a mid-laying feed for laying hens. 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 middle stage of laying eggs 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. [0003] Fe...
