Enzymolysis method of chicken intestinal canals, carp feed containing intestinal canals and feed preparation method

Abstract

The invention relates to an enzymolysis method of chicken intestinal canals, a carp feed containing intestinal canals and a feed preparation method, and belongs to the technical field of preparation of fish feeds. The invention aims at solving the problems of relatively high raw material prices and relatively low utilization rate of existing fish feeds. The enzymolysis method comprises the steps of: preprocessing the raw materials, mixing the intestinal canals, protease and water, and carrying out enzymolysis, wherein the protease is one of alkaline protease, papain, trypsin or neutral protease. The carp feed consists of the following raw materials in parts by mass: soybean meal, fish meal, enzymatically decomposed chicken intestinal canal protein, wheat middling, soybean oil, fish oil, phospholipid, choline chloride, calcium dihydrogen phosphate, sodium hydroxycellulose, a mineral element premix, multivitamins, methionine, threonine and lysine. A chicken intestinal canal protein feed,namely the carp feed contains trophic factors for promoting development of the intestinal tracts and is capable of improving activities of intestinal tract complements C3 and C4 and lysozyme, therebyimproving immunologic functions of the intestinal tracts.

Description

technical field [0001] The invention belongs to the technical field of fish feed preparation, and in particular relates to an enzymatic hydrolysis method of chicken intestines, carp feed containing chicken intestines and a feed preparation method. Background technique [0002] In 2018, the total output of aquatic products in the country was 64.5766 million tons, of which the aquaculture output reached 49.9105 million tons. With the development of my country's aquaculture industry, the amount of feed consumed by aquatic animals has also increased sharply. In 2019, my country's aquatic animal feed output reached 2202.9 10,000 tons, which in turn leads to a shortage of feed raw materials for aquatic animals, especially a serious shortage of protein feed raw materials. The raw material of protein feed for aquatic animals is mainly fish meal, which has the advantages of high protein content and balanced amino acid, so it is the best protein feed raw material for aquatic animals. ...
