Abstract

Rainbow trout juvenile fish compound feed with low nitrogen and phosphorus emission is prepared from, by weight, 35-50 parts of compound protein component, 10-25 parts of compound grease compound, 1-5 parts of compound Chinese herbal medicine component, 2-5 parts of algae powder special component, 1-5 parts of microecological preparation, 10-15 parts of buckwheat middling, 10-15 parts of whole oat powder, 0.02-0.1 part of vitamin mixture and 0.1-0.5 part of mineral substance mixture. The feed can meet the requirements of rainbow trout juvenile fish for high protein, conform to the characteristics of sarcophagi of rainbow trout juvenile fish, promote growth, reduce nitrogen and phosphorus emission and improve the breeding efficiency.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a compound feed for juvenile rainbow trout with low nitrogen and phosphorus discharge. Background technique [0002] Rainbow trout belongs to Salmoniformes and Salmonidae. It is a kind of cold-water fish. Its origin is in the mountains and rivers along the Pacific coast of North America. Juvenile rainbow trout have a high demand for animal protein during the growth process, and insufficient nutrients and vitamins in the bait will cause deformities and malnutrition during the growth process, which will not only affect their individual growth and development, but also affect their subsequent development. adverse effects on farming. During the breeding process of rainbow trout, they like to swim and are active in nature, so they lose a lot of energy, and the bait they put in often has less energy substances, which cannot meet their needs. In addition, during the b...
