A kind of composite protein powder and its application

Abstract

The invention discloses a compound protein powder. The compound protein powder comprises the following components in parts by weight: 36-44 parts of chicken meal, 17.48-21.21 parts of soybean protein concentrate, 17.48-21.21 parts of corn protein powder, 9-11 parts of euphausia superba, 9-11 parts of beer yeast powder, 0.20-0.30 part of yeast extract, 0.04-0.06 part of grape seed extract and 0.01-0.02 part of folium cortex eucommiae. The invention also discloses an application of the compound protein powder. The compound protein powder disclosed by the invention not only can replace partial fish powder for use, but also cannot reduce the raising effect, and also can reduce the emission of nitrogen and phosphorus of hybrid snakeheaded fish.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to a composite protein powder and its application. Background technique [0002] Channa argus and Channa maculate belong to the order Perciformes, the suborder Anabantoidei, the family Channidae, and the genus Channa. The hybrid snakehead is the F1 generation obtained by crossing the snakehead as the male parent and the snakehead as the female parent. Hybrid snakehead is a ferocious carnivorous fish. It grows rapidly, has tender meat, delicious taste and rich nutrition, and is deeply loved by consumers. [0003] The hybrid snakehead is one of the main freshwater cultured fishes in Guangdong Province. At present, the breeding area of ​​hybrid snakeheads exceeds 30,000 mu, the breeding output reaches more than 160,000 tons, the ingestion of compound feed exceeds 200,000 tons, and the annual output value exceeds 3 billion yuan. At present, the formula of artificial compound feed mainly uses...

But on the other hand, the global fishmeal resources are increasingly in short supply, and the price keeps rising, which leads to high feed prices, increased breeding costs, and is not conducive to the protection of marine fishery resources.

A large number of researches on reducing the consumption of fishmeal have been carried out on carnivorous fish at home and abroad. The research results show that the main limiting factor of replacing fishmeal with animal and plant protein is the decrease in food intake rate and growth and the increase in feed ratio after replacing fishmeal. The main reason is that the replacement of fishmeal Afterwards, the palatability of the feed decreased, the amino acid was missing or unbalanced, the unknown growth factor was missing, and the anti-nutritional factor exceeded the tolerance threshold of the fish.
