Early starter disease-resisting and fattening feed for bighead carp and silver carp

Abstract

The present invention belongs to the field of aquatic feed, in particular relates to a special feed capable of improving the ingestion rate and immunity of bighead carp and silver carp early starters in spring. The feed particularly comprises the following components by weight: 15-20 parts of wheat bran, 15-20 parts of soybean cake, 10-15 parts of rice bran, 5-10 parts of fish meal, 5-10 parts of Antarctic krill powder, 5-8 parts of feed grade seaweed powder, 0.5-1 part of pounce, 1-2 parts of GuShu brand aquatic compound multivitamin type I, 1-2 parts of sodium alginate powder, 0.1-0.3 part of antioxidants, 5- 8 parts of plant additives and 0.02-0.1 part of sodium citrate. Among the antioxidants, beta glucan, vitamin E and glutathione have synergism, and can reduce the impact of external factor and stress on the growth performance, ingestion rate of bighead carp and silver carp in early spring, and improve the breeding survival rate and growth rate. The plant additives can increase the food intake of bighead carp and silver carp and improve the disease resistance of bighead carp and silver carp.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a special feed for improving the feeding efficiency and immunity of bighead carp and silver carp in early spring. Background technique [0002] In spring, as the air temperature and water temperature continue to rise, the activities of various pathogenic organisms are strengthened, which easily infects fish with various diseases. The pathogen resistance is relatively poor, and it is easy to be infected with various diseases, causing a large number of fish deaths in ponds, causing large losses to farmers, and seriously affecting the growth of surviving individuals in the later stage. [0003] Bighead carp and silver carp belong to the four major freshwater fishes, and are widely cultivated and eaten in my country. Because bighead carp and silver carp have similar living habits and have certain complementarity, it is recommended to mix and stock bighead carp and silver carp ...

AI Technical Summary

Problems solved by technology

Because bighead carp and silver carp live in the middle and upper layers of the water body, the temperature gradually warms up in early spring. Generally, when the water body temperature reaches above 15°C, bighead carp and silver carp start to eat. low and low, especially for bighead carp and silver carp on the surface of the water body, causing them to be blocked from eating due to high and low temperatures, affecting growth and health
