Embodiment 1

[0011] An anti-stress enhancer of portunus trituberculatus, weighed according to the following parts by weight: glutamine dipeptide 4, vitamin C-2-monopolyphosphate 18, vitamin E acetate 12, taurine 15, lemon Acid 12, soybean flavonoid 2, glucose 39, the above-mentioned raw materials are uniformly mixed to prepare an anti-stress enhancer.

Embodiment 2

[0013] The antistress enhancer of Portunus trituberculatus is basically the same as Example 1, except that in the raw material formula: glutamine dipeptide is 3, vitamin C-2-monopolyphosphate is 20, vitamin E acetate is 10, taurine 20, citric acid 10, soybean flavonoid 1, glucose 30, and the above raw materials are uniformly mixed to prepare an anti-stress enhancer.

Embodiment 3

[0015] The antistress enhancer of Portunus trituberculatus is basically the same as Example 1, except that in the raw material formula: glutamine dipeptide is 5, vitamin C-2-monopolyphosphate is 15, vitamin E acetate is 15, 10 for taurine, 15 for citric acid, 3 for soybean flavonoids, and 50 for glucose. The above-mentioned raw materials are uniformly mixed to prepare an anti-stress enhancer.

Abstract

The invention discloses an anti-stress reinforcing agent for portunus trituberculatus and an application thereof, and is characterized in that the anti-stress reinforcing agent is prepared by evenly mixing the following raw materials in parts by weight: 3-5 parts of glutamine dipeptide, 15-20 parts of vitamin C-2-single-polyphosphate, 10-15 parts of vitamin E acetate, 10-20 parts of taurine, 10-15 parts of citric acid, 1-3 parts of soybean flavonoids, and 30-50 parts of glucose. The mass percentage content of the anti-stress reinforcing agent in a feeding feed is 0.06-0.08%. The anti-stress reinforcing agent has the advantages that: the adding amount of the anti-stress reinforcing agent in the feed is only 0.06-0.08%, so that the resistance of portunus trituberculatus on pathogenic microorganisms and the ability of portunus trituberculatus to resist the environmental stress can be significantly improved, thus the survival rate of portunus trituberculatus in full cycle aquaculture is improved, the survival rate can be increased by 16.5-19%, the average body weight can be increased by more than 10%, and the aquaculture yield is increased by 26.9-31.3%.

Description

technical field [0001] The invention relates to a feed additive for portunus trituberculatus, in particular to an anti-stress enhancer for portunus trituberculatus and application thereof. Background technique [0002] Under the conditions of intensive crab farming, the cultured crabs are susceptible to physiological stress caused by drastic changes in environmental factors such as temperature, salinity and pH, chemical factors such as heavy metals in water, ammonia nitrogen, etc., and biological factors such as microorganisms. Reaction, affecting the reproduction, growth, disease resistance and viability of crabs, resulting in lower survival rate of cultured crabs, slower growth rate, and even a decline in the quality of crab meat. Therefore, it is necessary to develop anti-stress feed additives for crabs to improve the survival rate of crabs and promote the growth of crabs. The Chinese patent application number is CN201010595413.0, and the name is an anti-stress enhancer ...
