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.
