Abstract

The invention discloses a biologic emulsifier for aquatic animal feed. The biologic emulsifier is characterized by being prepared by two or more than two of sophorolipid, rhamnolipid and trehalose. The sophorolipid, the rhamnolipid and the trehalose and the like in the emulsifier are all secondary metabolites generated by microbial fermentation, can be naturally metabolized and degraded, do not cause residues in aquatic products, and do not influence water quality. The biologic emulsifier can remarkably improve feed fat digestion utilizing rate of fishes, shrimps and crabs and the like, reduces bait coefficient, remarkably improves production performances of aquatic animals, improves body immune function, reduces morbidity and mortality of the animals, and remarkably improves economic returns.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and is a feed additive for improving the fat utilization rate of aquatic animal feed and the quality of aquatic products by using a biological emulsifier, specifically a biological emulsifier for aquatic animal feed. Background technique [0002] With the development of modern aquaculture industry, more and more full-price compound feeds have become the main source of feed for aquatic animals. In order to meet the special nutritional needs of aquatic animals, producers often need to add fats and oils to the feed, including fish oil, soybean oil, rapeseed oil, etc. These oils are not completely consistent with the oil and fat needs of aquatic animals, and the utilization of these oils by aquatic animals is limited. Adding an emulsifier to the feed to emulsify the oil is one of the methods to increase the utilization rate of oil and improve the quality of aquatic products. However, traditi...
