Abstract

The invention discloses feed capable of promoting molt of crayfish and a preparation method thereof and belongs to the field of agricultural feed. The feed is prepared by mixing rice bran powder, soybean meal, fish meal, seaweed powder, bone meal, squid liver paste, cholesterol powder, tricalcium phosphate, calcium hydrogen phosphate, vitamin D3, tea seed meal, potassium dihydrogen phosphate, bile acid and aquatic complex microbial agent and then performing fermentation. The feed has the advantages that the molting hormone of the crayfish is increased by promoting the crayfish to absorb the high cholesterol in the feed to synthesize ecdysterone so as to increase the molt and growth speed of the crayfish; the feed can promote the molt of the crayfish, increase the immunity of the crayfish, increase the number of intestinal tract beneficial bacteria and purify water; drugs such as hormone and antibiotics are not added into the feed, and the feed is simple to prepare, safe in raw materials, rich in nutrition, scientific in compatibility, good in feeding attraction performance, low in cost and capable of increasing benefits.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a feed for promoting molt of crayfish and a preparation method thereof. Background technique [0002] Crayfish (scientific name: Procambarus clarkii), also known as: Procambarus clarkii, red crayfish and freshwater crayfish, belong to the phylum Arthropoda / subphylum crustacea / class of soft carapace / subclass of true soft carapace / decapod / gastral subclass Order / Crawfish family / Procambarus genus / Procambarus clarkii P. clarkii. Shrimp-like in shape but with a hard shell, the adult is about 5.6-11.9 cm long, dark red, the carapace part is nearly black, and there is a wedge-shaped stripe on the back of the abdomen. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. It also kills each other when food is scarce. Crayfish is rich in protein, magnesium, zinc, iodine, selenium, astaxanthin, etc. It is widely loved by people because of its rich nutrition, delic...
