Food intake promoting composition capable of improving food intake of pelteobagrus fulvidraco and application of food intake promoting composition

Abstract

The invention belongs to the field of feed, and discloses a food intake promoting composition capable of improving food intake of pelteobagrus fulvidraco and application of the food intake promoting composition. The composition comprises the following components of squid paste, fish dissolved pulp, taurine, betaine, dimethyl-beta-propiothetin and yeast hydrolysate. The pelteobagrus fulvidraco feedwith good food calling performance is prepared from the following components of fish meal, meat meal, soybean meal, peanut meal, dephenolized cottonseed protein, double-low rapeseed meal, porcine blood globulin powder, starch, cellulose, fish oil, soybean oil, an inorganic salt premix, a vitamin premix, choline chloride and amino acid. According to the composition, food intake promoting substances with the best food intake promoting effect on the pelteobagrus fulvidraco are screened through a maze method, the best food intake promoting effect of the squid paste, the yeast hydrolysate and thefish dissolved pulp on the pelteobagrus fulvidraco is obtained, and the weight gain effect of the pelteobagrus fulvidraco is the best when the food intake promoting composition is added into feed.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a food intake-promoting composition capable of improving the feeding of yellow catfish and an application thereof. Background technique [0002] In the process of intensive farming, yellow catfish is prone to poor food intake, and poor food intake of farmed fish for a long time will affect its growth rate and output, thereby affecting the economic benefits of farming. Therefore, it is very necessary to add food-promoting substances in the diet of the peltaceae. The addition of food-promoting substances in the feed can improve the palatability of the feed, so that aquatic animals can better utilize plant protein sources that they do not like to eat, which is conducive to the development and utilization of new raw materials and reduce the cost of breeding; it can increase the feeding rate of fish, Improve the growth rate and output of farmed fish, and improve the efficiency of farm...

AI Technical Summary

Problems solved by technology

The selection and combination of ingestion-promoting food substances play a vital role in the growth of yellow catfish, but there is no effective food-intake composition for yellow catfish at present
