Problems solved by technology

Existing studies have shown that one of the main factors affecting the utilization of plant protein sources by fish is the reduction of feed palatability after adding plant protein. Substances increase, thereby affecting the appetite of aquatic animals, reducing food intake and stunting growth (Gomes et a1.1995; Bureau et al.1998)

Abstract

The invention provides a low fish meal compound feed capable of improving ingestion rate of cultured weever. The compound feed consists of the following components in part by weight: 26 to 31 parts of fish meal, 2 to 10 parts of whole shrimp powder, 12 to 16 parts of soy protein concentrate, 8 to 12 parts of fermented bean pulp, 9 to 12 parts of peanut cake, 20 to 23.5 parts of strong flour, 0.8 to 1.2 parts of calcium dihydrogen phosphate, 1.5 to 2 parts of fish oil, 1 to 2 parts of bean oil, 2 parts of vitamin and mineral salt premix, 0.2 to 0.4 part of betaine, 0.3 to 0.5 part of taurine, 0.05 to 0.1 part of citric acid, 0.3 to 0.5 part of Chinese asafetida, 0.1 to 0.2 part of glycine, 0.5 to 1 part of glutamic acid, and 0.05 to 0.12 part of alanine. The low fish meal compound feed canpromote ingestion and food digestion of fish, so that the utilization rate of the feed is improved, the coefficient of the feed is reduced, and the raising cost is reduced.

Description

technical field [0001] The invention belongs to animal breeding feed, in particular to a perch compound feed. Background technique [0002] In recent years, with the rapid development of intensive farming, artificial feed has become more and more important in the aquaculture industry. Fishmeal is the most important protein source in the feed industry. However, due to the depletion of resources and the impact of bad weather, the world's total fishmeal production is gradually declining, resulting in an imbalance between supply and demand, increasing the price of fishmeal and raising the cost of breeding, which seriously restricts development of the aquaculture industry. The development of new feed protein sources is one of the technical ways to save fishmeal consumption (Ai Qinghui et al. 2005). Compared with animal protein, plant protein has become one of the ideal protein sources in feed due to its wide range of sources and low price. Existing studies have shown that one ...
