Grass carp feed for decreasing incidence of diseases

Abstract

The invention provides a grass carp feed for decreasing the incidence of diseases. The feed comprises the following components in parts by weight: 40-60 parts of fish meal, 20-40 parts of freshwater shrimp powder, 10-30 parts of pork liver powder, 10-20 parts of kelp powder, 60-80 parts of soybean meal, 20-40 parts of sorghum flour, 10-20 parts of soybean flour, 10-20 parts of barley flour, 20-30 parts of cottonseed meal, 10-20 parts of rapeseed meal, 5-15 parts of bran, 5-15 parts of clamworm powder, 10-20 parts of wheat middling, 5-15 parts of alfalfa meal, 20-30 parts of phosphatide, 4-6 parts of seaweed meal, 4-6 parts of maifan stone powder, 5-15 parts of vegetable oil, and 4-6 parts of core additives, wherein every 100 parts of core additives are prepared from the following components in parts by weight: 20-30 parts of garlic, 20-30 parts of bitter gourds, 10-20 parts of radix puerariae, 10-20 parts of radix isatidis, 5-15 parts of litsea cubeba, and 5-15 parts of folium artemisiae argyi. The grass carp feed provided by the invention not only can provide the grass carp with basic nutrient substances, but also can ensure the growth efficiency of the grass carp; and at the same time, the formula of the feed is optimized and is added with the core additives, so that the meat quality of the grass carp can also be improved, the safety is high, the raw material sources are abundant, and the price is low.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a feed for grass carp with reduced morbidity. Background technique [0002] Grass carp belongs to the genus Grass carp of Cyprinidae Cyprinidae. The common names of grass carp are: grass carp, oil carp, grass carp, white carp, grass carp, grass root (Northeast), mixed son, black herring, etc. English name: Grass carp.

Problems solved by technology

[0003] At present, there are several major problems in the cultivation technology of grass carp: First, in the environment of still water ponds in most of the aquaculture industry in our country, high-density aquaculture causes a large amount of aquatic animal excrement, residual bait, disinfectants, etc. A large amount of harmful substances are released, which increases the density of aquaculture, degrades the water environment, and aggravates aquaculture diseases. Many diseases have seriously threatened the efficiency of aquaculture.

However, the loss of feed in water and the accumulation of excreta have become the main pollution sources of water bodies, resulting in deterioration of water quality, large-scale reproduction of pathogens, decreased survival rate, increased dosage of medicines, frequent water changes, and increased breeding costs.
