Artificial mixed feed for preventing and/or improving white feces disease of penaeus vannamei boone and preparation method thereof

Abstract

The invention discloses an artificial mixed feed for preventing and / or improving white feces disease of penaeus vannamei and a preparation method thereof. The artificial mixed feed comprises the following components: fish meal, spray-dried pig blood ball powder, squid liver paste, shrimp shell powder, soybean protein concentrate, soybean meal, peanut kernel cake, low-gluten flour, soybean phospholipid oil, monocalcium phosphate, fermented soybean meal, a multi-vitamin and multi-mineral mixture, choline chloride, sodium chloride, an antioxidant, a mildew preventive, a composite Chinese herbal medicine and a short-chain fatty acid mixture. The artificial mixed feed can effectively reduce the stress sensitivity of the penaeus vannamei to high temperature, effectively remove active oxygen freeradicals generated in the penaeus vannamei body, regulate the metabolic disturbance of free radicals caused by stress, repair hepatopancreas damage, inhibit the reproduction of harmful vibrios, reduce the damage of the vibrios to the hepatopancreas, prevent the penaeus vannamei from generating white feces disease in high-temperature seasons, and reduce the probability of the white feces disease,thereby improving the culture success rate and the yield of farmers.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to an artificial compound feed for preventing and / or improving white stools of Penaeus vannamei and a preparation method thereof. Background technique [0002] Penaeus vannamei is a euryhalal species, and it is cultivated from north to south across the country. The annual high temperature season is a fast-growing season for Penaeus vannamei. However, due to the high temperature period, the prawns eat more and the amount of feed increases rapidly. Along with the increase of residual bait and feces in the water body and the content of Vibrio easily exceeds the standard, it will eventually lead to white stools of shrimps. Now the incidence of white stools of Penaeus vannamei is becoming more and more common, no matter what season, what farming mode, or what region it occurs. [0003] At present, in the industry, there are two opinions on the causes of white stools of Penaeus vann...

AI Technical Summary

Problems solved by technology

[0003] At present, in the industry, there are two opinions on the causes of white stools of Penaeus vannamei: one is caused by bacterial infection-some Vibrio substances in the water body are released in large quantities in the water body along with feed, residual bait, organic debris and dead algae Propagation, shrimp ingestion causes hepatopancreas tissue lesions and intestinal mucosal shedding; second, algae toxins lead to instability of algae in water bodies during high temperature periods, and release some toxins after algae die, leading to enlargement, atrophy of shrimp hepatopancreas, enteritis, etc. Secondary lesions that eventually lead to white stools in prawns
