Embodiment 1

[0064] Compound enzyme formula: xylanase 15000U / g, mannanase 1000U / g, galactosidase 50U / g, cellulase 700U / g, β-glucanase 1500U / g, α-amylase 200U / g, protease 2000U / g, pectinase 200U / g.

[0065] 360 4-week-old Aviin broiler chickens with similar body weight and health were selected in the experiment, and were randomly divided into 4 groups, with 3 repetitions in each group and 30 chickens in each repetition. All experimental broilers were raised in cages, and every two chickens were raised in the same cage. The experimental diet was flour, with free access to food and water, and conventional feeding and management. The pre-feeding period is 4 days, and the formal test period is 4-6 weeks old, a total of 21 days. The experimental design is as follows:

[0085] Select 720 healthy, 22-week-old Baowans brown-shell hens with similar body weight, and divide them into 4 groups randomly, with 4 repetitions in each group and 45 chickens in each repetition. According to statistics, it is required that the egg production rate of each group is not significantly different (P>0.05), and then enters the formal period, and the chickens in this test are raised in cages. Two diets were designed in the experiment, the control group was the traditional corn soybean meal diet, and the experimental group used rapeseed meal and cottonseed meal instead of part of the soybean meal, and kept the same nutritional level.

Abstract

The invention belongs to the technical field of feed additives, and in particular relates to complex enzyme for a feed. The complex enzyme comprises 7,500 to 15,000U/g of xylanase, 1,000 to 3,000U/g of mannose, 50 to 80U/g of galactosidase, 200 to 700U/g of cellulose, 500 to 1,500U/g of beta-glucanase, 150 to 1,000U/g of alpha-amylase, 2,000 to 10,000U/g of protease and 100 to 200U/g of pectinase. By adding corresponding enzyme preparations, the anti-nutrition function of the complex enzyme is reduced, the feed utilization is improved, and the animal production efficiency is improved, so the problems that the utilization rate of animal feed raw materials is low and the animal production performance is inhibited are effectively solved; meanwhile, the complex enzyme has the advantages of reasonable raw material mixing, good effect, and low overall cost.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a compound enzyme for feed. Background technique [0002] The cost of feed accounts for 60-80% of the cost of breeding production. Conventional feed materials such as corn, wheat, and cakes all have a certain amount of anti-nutritional factors, the most common of which are non-starch polysaccharides. [0003] Non-starch polysaccharides (NSP) are the general term for all carbohydrates in plant tissues except starch and monosaccharides, mainly composed of cellulose, hemicellulose, pectin, etc., and are the main components of plant cell walls. Hemicellulose mainly includes arabinoxylan, mannan, β-glucan, galactose and the like. Among them, due to the high water holding capacity of soluble NSP, the animal itself cannot be decomposed, which will increase the viscosity of chyme in the animal intestine, hinder the release of nutrients, and affect the activity of animal digestive...
