Grass carp feed for resisting stress

Abstract

The invention relates to a feed, in particular to a grass carp feed for resisting stress. The grass carp feed consists of the following substances in parts by weight: 15-25 parts of meat and bone meal, 5-10 parts of broad bean protein powder, 15-25 parts of soybean meal, 15-25 parts of rapeseed meal, 15-22 parts of cottonseed meal, 15-25 parts of corn protein powder, 10-15 parts of tapioca, 15-25 parts of malt roots, 8-12 parts of rice bran, 5-10 parts of soybean oil, 3-5 parts of bentonite, 0.5-0.8 part of a fat emulsifying agent, 0.5-0.8 part of choline chloride, 0.5-0.8 part of calcium dihydrogen phosphate, 5-8 parts of a herba artemisiae capillaris extract, 1-3 parts of a vitamin premix, 1-3 parts of a mineral premix, 1-3 parts of zeolite powder, 0.5-0.8 part of alpha-ketoglutaric acid, 0.1-0.5 part of curcumin, 0.05-0.09 part of tea polyphenols and 0.05-0.09 part of taurine. According to the grass carp feed provided by the invention, various green feed additives are added, so that the digestion and utilization rate of the feed by the grass carps is increased, the immunization, the oxidation resistance and the stress resistance of grass carps are strengthened, the usage of drugs for preventing diseases in the breeding process is reduced or avoided, sufficient digestion and quick and high absorption of nutrients are increased, requirements for quick growth of the grass carps are met, and the feed conversion is increased.

Description

technical field [0001] The invention relates to a feed, in particular to an anti-stress grass carp feed. Background technique [0002] At present, in the intensive farming mode of grass carp, in order to pursue high yield, the stocking density of grass carp is too high and a large amount of feeding, etc., lead to the deterioration of the breeding water environment, and the stress of poor water environment will lead to immunosuppression of farmed fish and increase the occurrence of diseases Opportunity. Grass carp is a lower vertebrate, which is easily induced by stress damage caused by adverse environmental factors in aquaculture water, resulting in frequent occurrence of diseases. The survival rate from fry to adult fish is less than 30%, which has caused huge economic losses to the grass carp aquaculture industry. loss. In addition, in order to prevent fish diseases, a large amount of antibiotics and hormones are added to the feed, resulting in many problems such as drug...

[0002] At present, in the intensive farming mode of grass carp, in order to pursue high yield, the stocking density of grass carp is too high and a large amount of feeding, etc., lead to the deterioration of the breeding water environment, and the stress of poor water environment will lead to immunosuppression of farmed fish and increase the occurrence of diseases Opportunity

Grass carp is a lower vertebrate, which is easily induced by stress damage caused by adverse environmental factors in aquaculture water, resulting in frequent occurrence of diseases. The survival rate from fry to adult fish is less than 30%, which has caused huge economic losses to the grass carp aquaculture industry. loss

In addition, in order to prevent fish diseases, a large amount of antibiotics and hormones are added to the feed, resulting in many problems such as drug resistance and drug residues, which have brought great harm to the sustainable development of aquaculture industry, aquatic product safety and human health.
