Abstract

The invention relates to a preparation method of a rainbow trout feed comprising following components in percentage by weight : 18-30 of fish meal, 15-25 of blood meal, 8-18 of bean cake meal, 4-10 of bran, 3-7 of wheaten flour, 4-10 of cornmeal, 6-9 of fish liver and glandular meal, 7-15 of vegetables, 1-3 of feed mineral supplement, 1-3 of vegetable oil and 1-2 of various vitamins. The components are poured into a fish feed stirring mill to be stirred for 20 min in proportion, the mixture is taken out and is poured into a multi-purpose ring model type soft pelleter to be heated and processed into soft particle feed and is then screened by a 40-mesh filter screen, and the weight of each particle is 0.1 g.

Description

technical field [0001] The invention relates to a preparation method of fish feed, in particular to a preparation method of rainbow trout feed. Background technique [0002] Rainbow trout is a cold-water carnivorous fish. The most suitable temperature is 16-18 degrees. In natural waters, it mainly eats zooplankton, aquatic insects, juvenile fish, and shrimp. At present, with the popularization of artificial feeding, fresh feed is the main feeding method, but the cost is relatively high, so the development of rainbow trout is limited, which is very unfavorable to the growth of rainbow trout, so a reasonable ratio is required. All are relatively balanced high-quality compound pellet feed. Contents of the invention [0003] The purpose of the present invention is to provide a kind of compound pellet feed which is suitable for rapid growth of rainbow trout with reasonable ratio of various nutrients. [0004] The solution to its technical problems is: 18%-30% of fish meal, 1...
