The invention discloses a feed for grass carps. The feed consists of the following raw materials in part by weight: 20 to 30 parts of protein source, 15 to 25 parts of energy source, 0.5 to 2 parts of compound vitamin, 2 to 6 parts of calcium hydrophosphate, 0.5 to 1 part of common salt and 5 to 15 parts of bonding agent, wherein the protein source may be one or a mixture of more of fish meal, bean pulp, cottonseed meal and rapeseed meal; the energy source may be one or a mixture of more of rice grain, corn, defatted rice bran and wheat bran; and the bonding agent may be bentonite, algae, alpha-starch, sodium polyacrylate or poly propenyl alcohol. The feed for grass carps has the advantages that the feed is manually prepared and is the complete feed which can meet various nutritional demands of grass carps, and the nutritional matters contained in the feed include protein, energy, vitamins, minerals and the like which are all necessary for grass carps, so that an aim of promoting the growth of grass carps is achieved.
Description
[0001] technical field [0002] The invention relates to a fish feed, in particular to a grass carp feed. Background technique [0003] Grass carp, the rear side is flat, the color is blue and yellow, the head is wide and flat, the snout is slightly closed, the mouth is end-pointed, and there is no beard. Pharyngeal comb-shaped, two rows of sharp teeth, good at biting grass stems, is a typical herbivorous fish. Its intestines are longer, four or five times as long as its body. Grass carp is one of the main species of freshwater aquaculture in my country. It is cultivated almost all over the country and is a typical plant-eating fish. In natural waters, it mainly feeds on aquatic plants and other plants. [0004] At present, with the popularity of artificial feeding, compound feed is the main feeding method, but the nutrients in the ingredients are not very reasonable, which is very unfavorable to the growth of grass carp, so a reasonable ratio is required, and all nutrien...
