Feed capable of improving immunity of crayfish

Abstract

The invention relates to the technical field of feeds, in particular to a feed capable of improving the immunity of crayfish. The feed capable of improving the immunity of crayfish consists of the following raw materials in parts by weight: 35-50 parts of soybean meal, 16-23 parts of peanut cake, 3-9 parts of corn oil, 2-10 parts of brewer's spent grain, 10-16 parts of fish meal, 15-22 parts of earthworm powder, 5-12 parts of sweet potato residue, 1-5 parts of bitter grass, 3-9 parts of ragwort, 0.4-1.1 parts of compound vitamin, 2-7 parts of an additive and 4-10 parts of a traditional Chinesemedicine preparation. The feed capable of improving the immunity of crayfish is cheap and easy to obtain in raw material, low in production cost and comprehensive and rich in nutrition, is capable ofcomprehensively and sufficiently providing the nutrients required for the growth of crayfish, is high in the feed utilization rate and high in palatability, and is capable of effectively improving the immunity of crayfish and reducing the prevalence rate after long-term feeding.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed capable of improving the immunity of crayfish. Background technique [0002] Crayfish is a lobster-like crustacean that lives in fresh water. Its scientific name is Procambarus clarkii, also known as red crayfish or freshwater crayfish. Procambarus clarkii is the most widely distributed invasive alien species among crustaceans. Procambarus clarkii forms an absolute competitive advantage in the local ecological environment because of its omnivorous, fast growth and strong adaptability. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. It also kills each other when food is scarce. Procambarus clarkii has become an important economically farmed species in China in recent years. [0003] The growth cycle of crayfish is relatively short. It only takes about half a year for a crayfish to go from giving birth, hatching to maturity. However, t...

Problems solved by technology

However, due to shallow and turbid pond water, water pollution, insufficient light and mold infection, crayfish will also have various diseases, such as black gill disease, soft shell disease, rotten tail disease, etc.

The existing artificial propagation methods usually place crayfish in a clear water environment to ensure the cleanliness of crayfish, but cause a high mortality rate of crayfish
