Problems solved by technology

At present, with the popularity of artificial feeding, compound feed is the main feeding method, but the nutrients in the ingredients are not very reasonable, and the content of various proteins and vitamins is relatively low, which is very unfavorable to the growth of tilapia. Therefore, it is necessary to A high-quality fish feed with reasonable ratio and relatively uniform nutrition

Abstract

The invention relates to a preparation method of tilapia feedstuffs. The tilapia feedstuffs comprise the following components by weight percentage: 6-10 of fish meal, 18-37 of bean cakes, 4-9 of locust tree leaves, 18-25 of vegetable dreg, 4-8 of rice bran, 10-16 of wheat bran, 3-7 of barley, 4-10 of maize, 0.5-1 of common salt, 2-5 of mineral additive and 0.5-2 of multi-vitamin. The preparation method of the tilapia feedstuffs comprises the following steps: combining the fish meal, the bean cakes, the locust tree leaves, the vegetable dreg, the rice bran, the wheat bran, the barley, the maize, the common salt, the mineral additive and the multi-vitamin together in a certain proportion, uniformly stirring the mixture, pouring the mixture into a pulverizer, pulverizing the mixture, using a cycle mode soft particle unit to produce the mixture into the soft particle feedstuffs and sieving the soft particle feedstuffs through 40 meshes. The weight of each particle is 0.1 gram.

Description

technical field [0001] The invention relates to a preparation method of fish feed, in particular to a preparation method of tilapia feed. Background technique [0002] Tilapia is the most widely farmed fish in the world after carp. Tilapia is an omnivorous fish. In natural waters, it mainly eats zooplankton, phytoplankton, aquatic insects, juvenile fish, and shrimp. At present, with the popularity of artificial feeding, compound feed is the main feeding method, but the nutrients in the ingredients are not very reasonable, and the content of various proteins and vitamins is relatively low, which is very unfavorable to the growth of tilapia. Therefore, it is necessary to A high-quality fish feed with reasonable ratio and relatively uniform nutrition. Contents of the invention [0003] The purpose of the present invention is to provide a high-quality granular feed suitable for the rapid growth of tilapia with reasonable ratios of various nutritional components. [0004] Th...
