Feed for breeding crabs

Abstract

The invention provides a feed for breeding crabs. The feed comprises the following components in parts by weight: 30 parts of soybean meal, 43 parts of rape seed cakes, 8 parts of cottonseed meal, 16parts of corn germ cakes, 2 parts of yeast powder, 20 parts of rice bran, 10 parts of brewer's grains, 0.3 part of table salt, 0.3 part of liquid vitamin C, 15 parts of radix isatidis, 18 parts of heartleaf houttuynia herbs for crabs, 8 parts of nardostachys roots, 11 parts of endothelium corneum gigeriae galli and 13 parts of herba lysimachiae. The feed disclosed by the invention has the beneficial effects of promoting digestion, promoting the crabs to grow quickly, increasing the yield of the crabs, reducing breeding cost and improving the disease preventing capacity and immune competence ofthe crabs.

Description

technical field [0001] The invention belongs to the technical field of crab breeding, in particular to a feed for growing crabs. Background technique [0002] With the expansion of grass crab breeding scale in my country and the increase of unit output, the disease resistance of freshwater crabs is often improved by adding feed additives. However, the current additives are mostly antibiotics, compounds, trace elements or hormones, etc. These additives are easy to cause residues. And it may cause cancer, deformity, mutation, and human health will be affected after eating. Feed additives play an important role in freshwater aquaculture. Therefore, seeking efficient and harmless feed is the key to improving the growth performance and disease resistance of crabs. . Contents of the invention [0003] The purpose of the present invention is to provide a feed for raising crabs that can promote digestion, accelerate the growth of crabs, increase the output of crabs, reduce the cost...
