Feed with low fish meal content and application thereof

Abstract

The invention discloses a feed with low fish meal content. The feed comprises the following components in parts by weight: 5-8 parts of import fish meal, 10-12 parts of chicken meal, 4-6 parts of meat and bone meal, 1-2 parts of spray drying blood powder, 4-6 parts of concentrated soybean protein, 8-12 parts of corn protein powder, 15-18 parts of peel-removing soybean meal, 7-10 parts of peanut meal, 2-3 parts of euphausia superba powder, 3-4 parts of Saccharomyces cerevisiae powder, 0.30-0.40 part of yeast extract, 0.20-0.30 part of mannan oligosaccharide, 0.01-0.02 part of Eucommia ulmoides leaf extract and 0.10-0.12 part of natural xanthophyll. The invention further discloses the application of the feed with low fish meal content. The feed with low fish meal content keeps the original effect in terms of growth performance and body color.

Description

technical field [0001] The invention relates to the field of feed, in particular to a low-fishmeal feed and its application. Background technique [0002] Pelteobagrus belongs to Siluriformes, Bagridae, and Pelteobagrus. Mainly distributed in the Yangtze River. Yellow catfish mostly move in still water or in slow-flowing rivers, and like to live at the bottom of the lake. During the day, they live in the bottom of the lake, and at night, they swim to the upper layer of the water to look for food. Pelter catfish is a carnivorous omnivorous fish that can be propagated artificially at present. Its tender meat, delicious taste and rich nutrition are deeply loved by consumers. [0003] Yellow catfish is a warm-water fish with strong adaptability and can be cultured in various waters. According to statistics, the aquaculture area of ​​yellow catfish across the country exceeds 50,000 mu, the aquaculture output reaches more than 200,000 tons, the ingestion of compound feed exceed...

AI Technical Summary

Problems solved by technology

[0004] However, 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 have been carried out on the reduction of fishmeal for carnivorous fish at home and abroad. The research results show that the main limiting factors for the substitution of animal and plant protein for fishmeal are the decrease in feed intake rate and growth and the increase in feed ratio after replacement. The main reason is that the replacement of fishmeal leads to feed Decreased palatability, missing or unbalanced amino acids, missing unknown growth factors, and anti-nutritional factors exceeding fish tolerance thresholds
