Embodiment Construction

[0020] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the claims.

[0021] 1. Test materials

[0022] Feed additive prepared by Bacillus subtilis protease and trypsin combined with enzymatic hydrolysis of chicken intestinal membrane protein products, mixed with rice bran powder and added to chicken feed, mixed as evenly as possible, so that layer breeders can eat freely.

[0023] 2. Experimental animals and diet

[0024] The experiment was carried out in No. 4 test chicken house of Hefei Yiang Poultry Co., Ltd. Breeder Farm. A total of 108 experimental breeders (18 male breeders and 90 female breeder chickens) were selected at the age of 30 weeks, with similar body weight and good health status, and were divided into three treatment groups: control group and experiment 1 group, experiment 2 group, each group 36 Only 6 replicates were set up, each replicated with 6 rats (1 male and 5 fe...

Abstract

The invention relates to the technical field of biology, in particular to a preparation method and application of a bacillus subtilis protease and trypsin combined enzymolysis chicken intestine membrane protein product, chicken intestine membrane protein is degraded through compound protease to generate a compound product containing small peptides, the content of the small peptides is increased by 6-12 times, and the content of the small peptides is increased by 6-12 times. The enzymolysis product is prepared into a feed additive to be fed into feed for egg breeding hens, and the laying rate, the fertilization rate and the hatching rate of the egg breeding hens can be increased.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a preparation method and application of an enzymatic hydrolysis product of chicken intestinal membrane protein. Background technique [0002] In recent years, with the continuous improvement of people's living standards, people's requirements for the quality of life are also rising. Chicken is loved by people because of its delicious meat quality, and has become one of the main meat products purchased by domestic consumers. At the same time, with the rapid development of my country's poultry breeding industry, the scale and quantity of laying hen breeding have also been greatly improved, thus ensuring the effective market supply of chicken products. However, the growth and development of layer breeders is affected by many factors and the egg production rate is low. Therefore, it is necessary to further meet the market demand by improving the reproductive performance of layer breeder...
