Compound feed for gynogenetic disease-resistant grass carps

Abstract

The invention discloses a compound feed for gynogenetic disease-resistant grass carps. The feed is prepared from the following raw materials: rice bran, soybean meal, rapeseed meal, starch, ryegrass, sudan grass, compound vitamin, chitosan, calcium hydrogen phosphate, sgrup, table salt and an antiviral additive, wherein the antiviral additive is composed of rhubarb, radix scutellariae, cortex phellodendri, radix sanguisorbae, liquorice, astragalus, fresh ginger, orange peel, allicin, herba houttuyniae and leonurus. The compound feed disclosed by the invention is suitable for grass carps and capable of meeting the requirement for nutrient elements required in the growth process of the grass carps, and meanwhile the antiviral additive is added, so that the immune functions of the grass carps are fundamentally enhanced, furthermore, the resistances of the grass carps to viruses are improved, the grass carps cannot be infected, and the human health cannot be injured. The compound feed is rich in raw material source, relatively low in cost, capable of respectively taking a synergistic effect and solving the problem of poor palatability of a common feed and very suitable for the grass carps and is not easily dissolved in water.

Description

technical field [0001] The invention relates to a compound feed, in particular to a compound feed for gynogenetic and disease-resistant grass carp. Background technique [0002] Grass carp belongs to the genus Grass carp of Cyprinidae Cyprinidae. It inhabits rivers and lakes in plain areas, and generally prefers to live in the middle and lower layers of water and areas with many aquatic plants near the shore. It is lively, swims quickly, and often looks for food in groups. A typical herbivorous fish. Overwinter in the deep waters of main streams or lakes. Broodstock have the habit of swimming in the breeding season. It has been transplanted to many countries in Asia, Europe, America and Africa. Because of its rapid growth and wide source of feed, it is one of the four major domestic fish in freshwater farming in China. [0003] However, among the four major carp species, grass carp is the most prone to diseases, mainly suffering from enteritis and red skin, which bring...

AI Technical Summary

Problems solved by technology

[0003] However, among the four major carp species, grass carp is the most prone to diseases, mainly suffering from enteritis and red skin, which brings great difficulties to grass carp breeding. In addition, hemorrhage disease is also a disease caused by reoguanidine virus that grass carp is very susceptible to. It is an infectious disease. During the breeding process, all fish from fingerlings to adult fish are susceptible to this disease. The incidence of this disease is extremely high, and the mortality rate is very high. It causes major economic losses to professional farmers every year.
