Jewfish feed phagostimulant and preparation method thereof

Abstract

The invention belongs to the technical field of feed additives and relates to a jewfish feed phagostimulant and a preparation method thereof. The weight of the phagostimulant in each ton of jewfish feed is 13.3-25.5 kg, and the phagostimulant in each ton of jewfish feed consists of the following raw materials by weight: 500-1,500 g of L-glycine, 1 000-3,000 g of L-alanine, 300-1,000 g of L-glutamic acid, 1,000-2,000 g of proline, 8,500-12,000 g of trimethyl glycine, 1,000-3,000 g of oxidized trimethylamine and 1,000-3000 g of squid organ meal. The invention has the advantages that the composite phagostimulant is free of overrich and over-fragrant stimulation, can be used for a long term, is safe and efficient and has no side effect; the raw materials of the feed phagostimulant are stable in source and simple in manufacturing technology and remarkably increase the feeding speed; the anti-stress capability of cultivating objects is remarkably improved while the food calling performance is enhanced, the cultivated jewfish has high survival rate and is brilliantly colored in body; and a majority of compositions in the phagostimulant are indispensable feed nutritional ingredients for growth of jewfish, so that the feed efficiency is improved, the feed coefficient is lowered and the cultivation cost is saved.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a feed attractant for sea bass and a preparation method thereof. Background technique [0002] Sea bass is one of the important marine economic fish in China. In recent years, with the rapid development of intensive farming, artificial compound feed has become more and more important in the sea bass farming industry. Fish meal is the most important protein source for sea bass feed. However, due to resource depletion and the impact of bad weather, the world's total fish meal production is gradually declining, the price of fish meal continues to rise, and the cost of breeding continues to rise, which seriously restricts the development of sea bass farming. . The development of plant protein sources to replace fishmeal has become one of the technical ways to save the amount of fishmeal used. However, according to more and more farming experience, the utilization of plant prot...

Problems solved by technology

However, according to more and more farming experience, the utilization of plant protein by sea bass is not ideal, there is a phenomenon of spit out when feeding, and the palatability of the feed is not good. decreased, while anti-nutritional factors and flavor substances increased, which affected the appetite of sea bass, reduced food intake, and stunted growth
