Feed for preventing desquamation bleeding of megalobrama amblycephala in high-density breeding condition

Abstract

The invention discloses feed for preventing desquamation bleeding of megalobrama amblycephala in a high-density breeding condition. The feed comprises the following components, by mass percentage: 14.8 of wheat, 15.0 of rice bran, 0.2 of choline chloride, 0.2 of betaine, 10.0 of corn germ dreg, 8.0 of starch maize slag, 18.0 of soybean meal, 6.0 of cottonseed meal, 10.0 of rapeseed meal, 4.0 of chicken meal, 9.0 of fish meal, 1.8 of calcium dihydrogen phosphate, 1.0 of soya-bean oil, 0.5 of lard, 0.5 of a Chinese herbal medicine preparation, and 1.0 of premix, and the total amount of the components is 100%. According to the invention, the Chinese herbal medicine preparation is added in the feed, and the amount of vitamin K3, vitamin C, and vitamin E is added in the feed formula, so that the nutrition metabolism function of the body is effectively enhanced; metabolism and fat conversion of the body are improved; the viscosities of the fat in the blood and the liver are effectively reduced; and conversion and absorption of the feed are improved. The feed has functions of invigorating the stomach and promoting digestion, protecting the liver and the gallbladder, resisting bacteria and virus, and promoting fat conversion and protein digestion and absorption; the stress resistance and immunity of the megalobrama amblycephala are improved; the survival rate is increased; and desquamation bleeding of megalobrama amblycephala is effectively prevented.

Description

technical field [0001] The invention relates to a feed for aquaculture, in particular to a feed for preventing descaling and bleeding of bream under high-density feeding conditions, and belongs to the technical field of feed production. Background technique [0002] Bram bream, commonly known as: bream, also known as Wuchang fish, belongs to Cyprinidae, Cyprinidae, subfamily bream, and genus bream. Latin name: M.amblycephala Yih; English name: Bluntnose black bream, Wuchangfish, Bluntsnout bream. The meat is tender and smooth, and the taste is delicious. It is one of the main freshwater cultured fish in my country. The bream is mainly produced in the middle and lower reaches of the Yangtze River, and most of them are cultured in the south. The peak growth period is from June to October every year, and it is easily affected by high temperature climate. Compared with other conventional main fishes, the bream is not resistant to low oxygen and transportation. , in order to pu...

AI Technical Summary

Problems solved by technology

The bream is mainly produced in the middle and lower reaches of the Yangtze River, and most of them are cultured in the south. The peak growth period is from June to October every year, and it is easily affected by high temperature climate. Compared with other conventional main fishes, the bream is not resistant to low oxygen and transportation. , in order to pursue high efficiency and reduce breeding costs, farmers now mostly adopt high-density feeding models and high-energy and high-protein diets to achieve rapid growth. Therefore, under the influence of external adverse factors during the breeding process, various stresses are prone Shock reaction and disease, fish body hair hair, bleeding, descaling, death and other phenomena

In order to prevent stress and diseases, farmers often use large doses of antibiotics and antibacterial drugs, which has caused a series of secondary damages to the body such as liver and gallbladder damage, decreased immunity, drug residues, and drug resistance enhancement. Adverse consequences have had a certain impact on human food safety and the sustainable development of the aquaculture industry, and at the same time pose a certain threat to the interests of farmers
