Embodiment Construction

[0018] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the claims.

[0019] 1. Test materials

[0020] The feed additive prepared by enzymatically hydrolyzing goat casing protein with the fermentation liquid of Bacillus velesii is mixed with rice bran powder and added to the goose feed. The mixture is as uniform as possible so that the breeding geese can eat freely.

[0021] 2. Experimental animals and diet

[0022] The test was carried out in the breeding base of Wanxi White Goose Breeding Goose of Zhanyu Company, Lu'an City, Anhui Province, and the experimental animals were Wanxi White Goose breeding base of Lu'an Zhanyu Company. A total of 90 experimental geese with similar body weight and good health status were selected (18 male geese and 72 female geese), and were divided into three treatment groups: control group, experimental group 1, and experimental group 2, with 30 geese in ea...

Abstract

The invention relates to the technical field of biological pharmacy, in particular to a goat casing proteolysis product as well as a preparation method and application of the goat casing proteolysis product. Goat casing protein is degraded by bacillus velezensis protease to generate a small peptide-containing composite product, and waste casing segments for producing goat casings are smashed to obtain a product; and adding bacillus velezensis fermentation liquor into the obtained mashed material, mixing, and carrying out enzymolysis at 37 DEG C for 2-4 hours to obtain a bacillus velezensis protease enzymolysis casing protein product, the small peptide content of the enzymolysis product is increased by 3-12 times, and when the enzymolysis product is prepared into a feed additive to be fed into a breeding goose feed, the laying rate, the fertilization rate, the hatching rate and the healthy young rate of the breeding goose can be increased.

Description

technical field [0001] The invention relates to the technical field of biopharmaceuticals, in particular to an enzymatic hydrolyzate of goat casing protein, a preparation method and an application thereof. Background technique [0002] With the development of society and the improvement of living standards, people's requirements for quality of life are also increasing simultaneously. As a herbivore, goose meat products are more favored by consumers. However, Wanxi White Goose has always had the bottleneck problem of low reproductive rate. In order to improve the reproductive rate of Wanxi White Goose breeding geese, there have been related reports by adding microbial additives, but there is still room for further improvement in the effect. Bacillus Velez protease has its unique biochemical characteristics, and there have been related literature reports, but there is no relevant literature report on the use of this protease to degrade intestinal membrane proteins. In order ...
