Disease-resistant granulated feed for crucian and preparation method thereof

Abstract

The invention discloses disease-resistant granulated feed for crucian and a preparation method thereof. The feed is prepared from flour, spinach leaves, snail powder, parched black bean flour, mulberry twigs, loach powder, insect carapace powder, radix trichosanthis, pumpkin leaves, blood worm powder, phospholipid oil, forest frog's oviduct, salt, antioxidant and a microecological agent. Compared with the prior art, the disease-resistant granulated feed for crucian and the preparation method thereof have the advantages that functions of intestinal tracts and livers of fish bodies are improved, nitrogen and phosphorus emission is reduced, nutrition distribution in the feed is balanced, immunity of the fish bodies is greatly enhanced, meanwhile, the calcium content in fish is increased to a certain extent, a certain health care effect is achieved when the feed is eaten for a long time, the feed has the protection effect on a water body, the bearing capacity of the water body is reduced, and the yield of unit water body is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a disease-resistant granular feed for crucian carp and a preparation method thereof. Background technique [0002] Crucian carp is a common freshwater fish. It is an omnivorous fish with tender meat and high nutritional value. It contains protein, fat, calcium, phosphorus, iron and other minerals. In addition, its medicinal value is extremely high. The effects of deficient, eliminating lean, warming the stomach to eat, nourishing the vital energy, usually due to the low utilization rate of the feed in the pond culture, and then the eutrophication of the hard aquaculture water, high nitrogen and phosphorus emissions, heavy water pollution, and frequent fish diseases , so that its survival rate is reduced, seriously restricting the development of crucian carp aquaculture. Contents of the invention [0003] The object of the present invention is to provide a disea...
