Abstract

The invention provides duck feed containing lipase. The duck feed comprises the following components, by weight, 40-50 parts of wheat, 12-15 parts of rice bran, 10-13 parts of maize germ dregs, 5-10 parts of corn, 5-10 parts of rice bran dregs, 4-7 parts of rapeseed dregs, 3-6 parts of cottonseed meal, 3-5 parts of pre-mixed materials, 0.01-0.04 part of liquid phytase, 0.01-0.03 part of xylanase, and 0.01-0.03 part of lipase. Preferably, the lipase comprises aspergillus niger lipase. The invention further comprises a preparation method of the lipase. The duck feed can improve the digestion rate of thick fat, can improve quality of feed, is stable and lasting in function and higher in activity, achieves the purpose of reducing cost through reducing adding amount of fat.

Description

technical field [0001] The application of the invention relates to a duck feed containing lipase and a preparation method thereof, belonging to the technical field of feed processing. Background technique [0002] In recent years, with the rising price of energy feed raw materials, especially oil, how to improve the utilization rate of energy in feed, reduce the amount of added oil, avoid the harm caused by high oil, and save costs has become the focus of attention. For young animals and animals under stress and pathological conditions, the secretion of pancreatic lipase and bile acid in the body is very low. In order to pursue higher production performance of animals, the amount of fat added in feed is getting higher and higher. , and the body's own pancreatic lipase and bile acid secretion is relatively insufficient, which cannot fully hydrolyze fat, resulting in waste of fat; at the same time, fat indigestion also causes many complications. [0003] Energy is an importan...
