Environment-friendly compound feed for reservoir ctenopharyngodon idellus

Abstract

The invention relates to environment-friendly compound feed for reservoir ctenopharyngodon idellus and belongs to the technical field of fish feed. The feed comprises 10-15 parts of flour, 2-5 parts of fish meal, 5-10 parts of peanut meal, 3-8 parts of coconut meal, 3-8 parts of rubber seed meal, 3-10 parts of apple seed meal, 15-25 parts of rapeseed meal, 5-10 parts of citric acid waste, 20-25 parts of soybean meal, 1.5-3 parts of monocalcium phosphate, 0.3-0.5 part of decavitamin premix, 0.5-1 part of compound trace element premix, 0.03-0.1 part of mildew preventive, 0.02-0.1 part of glucan, 0.01-0.1 part of mannan oligosaccharide, 0.02-0.1 part of L-malic acid, 0.05-0.1 part of sodium butyrate and 0.05-0.1 part of bile acid. The feed can well promote the healthy development of the gut and thickening of the intestinal mucosa, reduce the adhesion hyperplasia of harmful germs on the gut, improve digestibility, reduce the occurrence of gut diseases, reduce the loss of nutrients and reduce pollution to water.

Description

technical field [0001] The invention relates to a feed for grass carp, more specifically, the invention relates to a compound feed for grass carp in an environment-friendly reservoir, which belongs to the technical field of fish feed. Background technique [0002] grass carp( Ctenopharyngodon idellus ), the only species of Cyprinidae, Cyprinidae, Arrow subfamily, and Grass carp, also known as white grass carp, grass root fish, thick fish, with a slightly cylindrical body, slightly flattened head, and laterally flattened tail; the mouth is Arc-shaped, without beards; the upper jaw is slightly longer than the lower jaw; the body is light tea yellow, the back is blue-gray, the abdomen is gray-white, the pectoral and pelvic fins are slightly gray-yellow, and the other fins are light gray.

AI Technical Summary

Problems solved by technology

[0008] The invention aims to solve the problem that the existing feed will increase the incidence of intestinal diseases of grass carp in the reservoir and eventually cause water pollution, and provides an environmentally friendly compound feed for grass carp in the reservoir, which can improve the quality, immunity and digestion of feed for grass carp in the reservoir The absorption efficiency makes the grass carp in the reservoir resistant to long-distance transportation, looks good, does not lose scales, and has a lot of mucus on the body surface. At the same time, the yield per unit area and breeding benefits are improved, and the pollution to the water body is reduced.
