Complex enzyme preparation for feed of mink in winter fur growth period

Abstract

The invention discloses a complex enzyme preparation for a feed of a mink in a winter fur growth period. The complex enzyme preparation for the feed of the mink in the winter fur growth period comprises the following six enzymes: amylase, acid proteinase, araboxylan enzyme, Beta-mannase, pectinase and phytase. The complex enzyme preparation can effectively fill the gap on endogenous enzyme of the mink, degrades the main antinutritional factors, namely, non-starch polysaccharides (NSP), in a vegetable feedstuff, reduces the gut digesta viscosity of the alimentary canal of the mink, and improves the digestibility utilization rate of the mink to the maize-bean pulp-fish meal type daily ration. By adding the complex enzyme preparation, the apparent metabolizable energy (AME) in the daily ration can be increased, the digestibility and utilization rate of the protein and starch can be raised, the excessive multiplication of spoilage organisms in the intestinal canal can be reduced, the microecological balance of the intestinal canal can be adjusted, the diarrhea rate is reduced, the premunition and the survival rate of the mink in the winter fur growth period can be increased, the feed conversion rate is raised, the average daily weight gain of the mink is increased, and the dimension of the skin of the mink is expanded, the costs of the feed and breeding are decreased, and the economic benefit is increased.

Description

technical field [0001] The invention relates to a fur animal feed additive, in particular to a compound enzyme preparation for mink in the winter hair growth period, and belongs to the technical field of fur animal breeding and feed processing. Background technique [0002] Mink is a carnivore, and its ability to digest plant feed is poor. Plant feed materials such as corn and soybean meal contain more non-starch polysaccharides (NSP) and phytic acid (Phytic acid), which are the main food for monogastric animals such as mink. Antinutritional Factors. Due to the lack of enzymes to decompose NSP in the mink body, it is difficult to release nutrients such as starch and protein in the cells. At the same time, NSP can increase the viscosity of chyme in the digestive tract and cause physiological changes, and interfere with the nutrient digestion, absorption and utilization of other components in the diet. , which leads to a decrease in the digestion and utilization of feed nutri...

Problems solved by technology

Due to the lack of enzymes to decompose NSP in the mink body, it is difficult to release nutrients such as starch and protein in the cells. At the same time, NSP can increase the viscosity of chyme in the digestive tract and cause physiological changes, and interfere with the nutrient digestion, absorption and utilization of other components in the diet. , leading to a decrease in the digestion and utilization of feed nutrients, and causing negative effects such as mink gastrointestinal diseases
