Functional carassius auratu feed as well as preparation method and application thereof

Abstract

The invention relates to a functional carassius auratu feed as well as a preparation method and application thereof. The functional carassius auratu feed comprises the following components in parts byweight of 40-60 parts of fish meal, 2-10 parts of yeast hydrolyate, 5-25 parts of fermented soybean meal, 0-10 parts of puffed soybeans, 0-20 parts of rice protein powder, 10-15 parts of flour, 1.5-3parts of calcium dihydrogen phosphate, 2-6 parts of soybean oil, 1-3 parts of zeolite powder, and 0.5-2 parts of a premix. The crude protein in the functional carassius auratu feed is greater than orequal to 45%, and is far higher than that in a conventional carassius auratu feed. The used protein raw materials are low in content of nutrient resistant factors, and part of raw materials have theefficacy of protecting and repairing intestinal tracts. The functional carassius auratu feed has the functions of protecting the liver and the gallbladder, protecting and repairing intestinal tracts,strengthening metabolism and the like. Breeding experiment results indicate that when the functional carassius auratu feed is used, the purpose that the specification of carassius auratu fries incubated in the same year and fed with the carassius auratu feed can achieve that of trade goods can be realized, the feed is low in coefficient, short in breeding period, healthy in bred carassius auratu bodies and high in breeding benefits, and the feed is worth of massive promotion.

Description

technical field [0001] The invention belongs to the field of feed processing, and in particular relates to a functional crucian carp feed, a preparation method and an application thereof. Background technique [0002] Crucian carp (Carassius auratu) has tender meat and high nutritional value. Every 100 grams of meat contains 13 grams of protein, 11 grams of fat, and contains a lot of calcium, phosphorus, iron and other minerals. Crucian carp has extremely high medicinal value. Its nature is flat and sweet, and it enters the stomach and kidney. Intensive farming of crucian carp is mainly concentrated in the northern Jiangsu area of ​​my country. There are also a large number of cultures in Lianghu and Jiangxi. Crucian carp is widely distributed. It is one of the main freshwater culture species and one of the important edible fish in my country. [0003] Although ordinary crucian carp has high nutritional value and good taste, its growth rate is slow. Generally, the splash fi...

AI Technical Summary

Problems solved by technology

Usually, common crucian carp is bred into large-scale fish species (with an average weight of about 100g) in the first year, and the incidence rate is extremely low. Disease, sexual maturity from April to May, slow growth, increased feed coefficient, increased breeding costs, and in summer, ponds where crucian carp is raised alone are prone to carp herpes type Ⅱ virus (commonly known as big red gills), with high mortality and heavy losses
