Feed capable of preventing liver and gallbladder syndromes of crucian carps under high-density raising conditions

Abstract

The invention discloses a feed capable of preventing liver and gallbladder syndromes of crucian carps under high-density raising conditions. The feed consists of the following components in percentage by weight: 15.0% of wheat, 13.0% of rice bran, 10.0% of corn alcohol lees, 15.0% of soybean meal, 6.2% of cottonseed meal, 5.6% of rapeseed meal, 2.0% of rice protein powder, 21.0% of imported fish meal, 4.0% of meat and bone meal, 2.0% of soybean oil, 1.5% of phosphatide oil, 1.7% of calcium dihydrogen phosphate, 0.2% of table salt, 0.2% of choline chloride, 0.2% of 65% lysine, 0.2% of methionine hydroxy analog-Ca, 0.1% of Vc phosphate ester, 0.1% of garlicin, 1.0% of a premix and 1.0% of a Chinese herbal medicine additive, wherein the total quantity of the components is 100%. Based on the formula technique of a traditional crucian carp feed, a Chinese herbal medicine preparation is added, besides, the dosage of vitamin C and the dosage of vitamin E are increased, through synergistic reaction of concerted application, the anti-stress capacity and the resistance of crucian carp organisms are improved, the occurrence of the liver and gallbladder syndromes of the crucian carps under the high-density raising conditions is effectively prevented, the survival rate of the crucian carps is increased, and the production levels and the economic benefits are increased.

Description

technical field [0001] The invention relates to feed for aquaculture, in particular to a feed for preventing crucian carp hepatobiliary syndrome under high-density feeding conditions, and belongs to the technical field of feed production. Background technique [0002] Crucian carp, Latin scientific name: Carassius auratus, referred to as crucian carp, commonly known as knife fish, is a common freshwater fish in Eurasia. It is one of the fishes of the genus Cyprinidae, Cypriniformes, Cyprinidae. All are produced. Crucian carp likes to live in groups and live in groups. The meat is tender and has high nutritional value. Crucian carp from February to April and August to December is the most plump, and it is one of the important economical edible fish in my country. It is one of the main freshwater cultured fishes in my country. It is mostly produced in the Yellow River Basin and the Yangtze River Basin, especially in artificial ponds along the coast of Jiangsu. [0003] In order...

AI Technical Summary

Problems solved by technology

[0003] In order to pursue high efficiency and reduce the cost of breeding, farmers now mostly adopt high-density feeding mode and high-energy and high-protein diet to achieve the purpose of rapid growth of crucian carp. Inflammatory reactions and diseases, especially hepatobiliary syndrome, mainly manifested as whitening of tail and dorsal fin rays of diseased fish, blackening of the body surface, dull color, edema, obesity, loose scales and easy fall off of fish body, and gills. There is a lot of mucus, and the gills are severely congested when the mucus is scraped off; when the abdominal cavity is opened, there is a large amount of ascites, and the liver is enlarged and brittle, and the color becomes lighter or red and white. The gallbladder is too large, dark green in color , the outer wall of the gallbladder has some silver outer membranes, the inner wall of the intestinal tract is red and congested, the intestinal tract is inelastic, and easy to break when pulled lightly, etc. When concurrent enteritis, gill rot, bacterial sepsis and other diseases, it will cause a large number of deaths

Crucian carp hepatobiliary syndrome has become one of the main diseases that endanger the production of crucian carp, which has a certain impact on the sustainable development of the aquaculture industry and also poses a certain threat to the economic interests of farmers
