preparation example Construction

[0029] In a preferred embodiment, the freshwater carnivorous fish feed is prepared by the following method: all feed raw materials are crushed through an 80 mesh sieve and mixed evenly, the mixed material is obtained, the mixed material is made of 2.0mm hard pellet feed by extrusion, after natural air drying treatment, the freshwater carnivorous fish feed is obtained. This technical scheme specifies the preparation method of freshwater carnivorous fish feed, which is simple to operate and conducive to retaining the original nutrient content of raw materials.

[0030] In a preferred embodiment, the enzymatic chicken pulp is prepared by the following method: the chicken skeleton frozen plate is frozen to 0-4 ° C, so that its moisture content reaches 70%-90%, and then it is crushed and ground into a slurry; According to the amount of addition, 1‰-10‰ of the total amount of material is added to the compound enzyme for enzymatic lysis; The complex enzyme consists of 85% neutral proteas...

Abstract

The invention discloses application of enzymolysis chicken pulp in fresh water carnivorous fish breeding, and belongs to the field of fish feed. The technical scheme is as follows: the water content of the enzymolysis chicken pulp is 40-60%, the protein content is 15-30%, the fat content is 20-30%, and the TVBN content is 100-300mg / 100g; the content of the acid soluble protein accounts for 75-100% of the content of the crude protein, the content of the amino acid accounts for 16.03% of the content of the protein, the content of the methionine accounts for 0.42% of the content of the total amino acid, and the content of the arginine accounts for 0.86% of the content of the total amino acid. The freshwater carnivorous fish feed is applied to the aspect of freshwater carnivorous fish feeding, solves the problem that an existing feed cannot provide comprehensive nutritional ingredients for largemouth black perches to a certain extent, and has the characteristics of low production cost, high nutritional value and capability of effectively promoting healthy and rapid growth of freshwater carnivorous fishes.

Description

Technical field [0001] The present invention belongs to the field of fish feed, in particular to an enzymatic chicken pulp application in freshwater carnivorous fish feeding. Background [0002] Micropterus Salmoides is an important freshwater carnivorous economic fish in China, and its farming scale has expanded year by year, with the production of China's largemouth bass reaching about 432,000 tons in 2018. In terms of breeding costs, feed usually accounts for about 60%-70%, and fishmeal as a high-quality donor of aquatic feed protein will account for 40%-60% of the total farming cost. Because of its high protein content, balanced amino acid content, rich in unsaturated fatty acids and its advantages in growing unnamed factors, it has always been the most important source of animal protein. With the increasing development of the feed industry and aquaculture industry, the total amount of feed is increasing year by year, while the production of fishmeal is basically unchanged, r...
