Abstract

The invention provides a probiotic rainbow trout feed and a preparation method thereof. The probiotic rainbow trout feed comprises main materials and auxiliary materials, wherein the main materials comprise fish meal, soybean cake powder, brewer's grains, blood powder and a probiotic leavening agent; and the auxiliary materials comprise bone meal, flour and vegetable oil. After the main materials are fermented through the formula probiotic starter, the probiotics can still keep activity after sterilization and puffing granulation, crude protein and dietary fibers of the main materials are made to have absorbability, and meanwhile, the food calling performance of the feed particles is improved.

Description

technical field [0001] The invention belongs to the technical field of modified feed, and in particular relates to a probiotic rainbow trout feed and a preparation method thereof. Background technique [0002] Rainbow trout, Oncorhynchus mykiss, is a cold-water pond fish of the genus Pacific Salmon in the family Salmonidae. Rainbow trout is an important cold-water fish widely farmed in the world. The mature individual has a brown-red longitudinal stripe along the lateral line, which looks like a rainbow, hence the name. It is native to the northern part of North America and the west coast of the Pacific Ocean. It mainly lives in low-temperature fresh water and has high water quality requirements for aquaculture waters. [0003] Rainbow trout are carnivorous fish. The larval stage of wild rainbow trout is mainly zooplankton, benthic animals, and aquatic insects; adult fish feed on fish, crustaceans, shellfish, and terrestrial and aquatic insects, as well as leaves and seed...
