Abstract

The invention relates to the technical field of cultivation feeds and particularly relates to a formula feed for cultivating grass carps. The formula feed is prepared from following raw materials in parts by weight: 30-50 parts of rice bran, 30-45 parts of wheat bran, 5-15 parts of bean cakes, 5-15 parts of fish meal and 1-5 parts of yeast powder. The feed is added with a mineral substance or a microelement premix which accounts for 1%-2% of the mass of the feed, and a vitamin mixture premix which accounts for 0.05%-15% of the mass of the feed. The formula feed for cultivating the grass carps is prepared by selecting a plurality of types of the raw materials and is comprehensive in nutrition and palatable; the immunity of the grass carps is improved and the healthy and rapid growth of the grass carps is ensured; the unit yield is high and the cultivated grass carps are large and fat and meat quality is delicious; the utilization rate of the feed is high.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a formula feed for grass carp aquaculture. Background technique [0002] Grass carp is a typical herbivorous fish with flattened back, blue-yellow color, broad and flat head, slight snout, end-to-end mouth, no beards, comb-shaped pharynx, two rows of sharp teeth, good at biting grass stems. The intestines are longer, four to five times the body length. In natural waters, they mainly feed on aquatic plants and other plants. 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. [0003] At present, grass carp is the largest species of fish cultured in my country, and the whole process of breeding basically uses artificial feed. The existing grass carp feed nutrition is not very reasonable, which is very unfavorable to the growth of grass carp, and mainly has the foll...
