Problems solved by technology

[0004] The above invention patents can improve the anti-stress ability of crucian carp to a certain extent, especially to alleviate the stress response caused by high-density breeding or high temperature, but in the case of low dissolved oxygen (1-3mg / L), high concentration of ammonia nitrogen and nitrite (0.1~1.5mg / L) water quality conditions, the anti-stress effect on crucian carp is not obvious

Embodiment 1

[0019] Calculated according to the mass percentage, the following raw materials are taken: 40% tea polyphenols, 20% taurine, 7% tryptophan, 1.5% compound amino acid chelated zinc, 0.5% yeast selenium, 8.5% mannan oligosaccharides, vitamin C7. 5%, 15% zeolite powder, all raw materials are fully mixed, and then after ultrafine pulverization, 100-120 mesh dry powder compound preparations are made, which is the compound feed additive for improving the anti-stress ability of crucian carp according to the present invention. And the prepared feed additive is added to crucian carp feed according to the weight percentage of 0.25%.

Embodiment 2

[0021] Calculated according to mass percentage, take the following raw materials: tea polyphenols 44%, taurine 17%, tryptophan 6%, compound amino acid chelated zinc 1.3%, yeast selenium 0.7%, mannan oligosaccharides 9%, vitamin C 8% , 14% of zeolite powder, all raw materials are fully mixed, and then after ultrafine pulverization, 100-120 purpose dry powder compound preparations are made, which is the compound feed additive for improving the anti-stress ability of crucian carp according to the present invention. And the prepared feed additive is added to crucian carp feed according to the weight percentage of 0.3%.

Embodiment 3

[0023] Calculated according to mass percentage, take the following raw materials: tea polyphenols 50%, taurine 10%, tryptophan 6%, compound amino acid chelated zinc 1.2%, yeast selenium 0.8%, mannan oligosaccharide 10%, vitamin C 9% , 13% of zeolite powder, all raw materials are fully mixed, and then after ultrafine pulverization, 100-20 purpose dry powder compound preparations are made, which is the compound feed additive for improving the anti-stress ability of crucian carp according to the present invention. And the prepared feed additive is added to crucian carp feed according to the weight percentage of 0.2%.

Abstract

The invention provides a compound feed additive for improving anti-stress ability of a crucian. The compound feed additive comprises tea polyphenol, taurine, tryptophan, organic zinc, organic selenium, mannan oligosaccharide, vitamin C and a carrier. After adding the feed additive at a weight percentage of 0.2-0.3% to basic formula feed of the crucian under severe water quality conditions with 1-3mg / L dissolved oxygen and the concentration of ammonia nitrogen and nitrite being 0.1-1.5mg / L, a survival rate and a weight gain rate of the crucian are increased, a feed coefficient is reduced at the same time, and the culture efficiency is improved.

Description

【Technical field】 [0001] The invention relates to a feed additive for crucian carp, in particular to a compound feed additive for improving the anti-stress ability of crucian carp. 【Background technique】 [0002] Crucian carp is a kind of omnivorous freshwater fish that is widely loved by people, and it is cultivated all over the country. However, with intensive farming, crucian carp suffers from many stress responses caused by changes in environmental factors, such as high-density farming, sudden changes in weather, and deterioration of water quality. Stress response is a protective mechanism of animals (including fish). However, long-term stress response will cause damage to the physiological functions of animals, resulting in reduced growth performance, low immunity, and even increased mortality. . The water quality conditions suitable for the growth of crucian carp are: water temperature 22-28°C, dissolved oxygen 6-9 mg / L, ammonia nitrogen 0-0.05 mg / L, nitrite nitrogen...
