Preparation method of marine fish peptide suitable for piglet daily ration

Abstract

The invention relates to a preparation method of marine fish peptide suitable for piglet daily ration; an enzyme engineering technology is applied to carry out directional enzymolysis on marine fish to generate nutritional oligopeptide, small peptide and other functional peptides, a fish protein peptide product is produced through special process treatment, and the fish protein peptide product hasthe advantages of high protein content, various amino acids and balanced content of various amino acids; the marine fish peptide can meet the requirements of growth and metabolism of piglets, contains a large amount of small peptide molecules, and is beneficial to absorption and utilization of the piglets; and the fish protein peptide contains low content of heavy metals and no aflatoxin, so thatpork cultured by taking the fish protein peptide as a piglet creep feed has low harm to human bodies. Through analysis on test results of creep feed tests and phagostimulant and preference tests, itfinds that addition of the fish protein peptide into the creep feed can effectively improve the phagostimulant, feed intake and average daily gain, reduces the feed conversion ratio, improves the utilization rate of the feed, and the fish protein peptide has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of piglet creep feed, in particular to a method for preparing marine fish peptides suitable for piglet diets. Background technique [0002] In recent years, with the rapid development of the aquaculture industry, the supply and utilization of feed raw materials have become important factors restricting the development of the feed industry. Fishmeal is rich in amino acids, balanced, and rich in various unknown factors that promote animal growth. It is cost-effective. , so it becomes the animal protein raw material of choice in feed, but China's fishery resources are scarce, and fishmeal mainly relies on imports, so how to efficiently use limited fishery resources to meet the needs of existing livestock and poultry is the primary problem we face. Protein is one of the most critical nutrients in the growth process of animals. The traditional theory holds that protein enters the digestive tract of animals and is...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for preparing marine fish peptides suitable for piglet diets, so as to solve the problem in the prior art that there are mainly two production processes for fish peptides, enzymatic hydrolysis and fermentation. The product is easily soluble in water, has a bitter and fishy smell, and absorbs moisture; the product obtained by the fermentation process is easily soluble in water, and the freshness is not easy to control, with bitter taste and moisture absorption. The above two methods are immature and there are still many problems. big flaw problem
