Example Embodiment

[0022] Example 1

[0023] A protective agent for the intestinal mucosa of Penaeus vannamei, comprising the following components in parts by weight: 20 parts of glutamine dipeptide, 10 parts of arginine, 7 parts of inositol, 12 parts of kudzu root, 13 parts of astragalus, oligomeric chitosan 18 parts of sugar, 6 parts of salvia miltiorrhiza, 14 parts of vitamin C phosphate.

[0024] The components of the health care agent were pulverized to 200 mesh and mixed uniformly. In the process of feed processing, the intestinal mucosal protective agent of Penaeus vannamei is used as an additive, and is added to feed raw materials according to the mass ratio of 0.1-0.2% to make functional feed. During the breeding process, every year from the end of June to the end of August, a cycle (4-5 days) is fed every 10 days.

Abstract

The invention provides an intestinal mucosa protective agent applied to penaeus vannamei. The intestinal mucosa protective agent is prepared from the following components in parts by weight: 15-20 parts of glutamine dipeptide, 10-15 parts of arginine, 5-10 parts of inositol, 10-15 parts of radix puerariae, 10-15 parts of radix astragali seu hedysari, 15-20 parts of chitosan oligosaccharide, 5-10 parts of radix salviae miltiorrhizae and 10-15 parts of vitamin C phosphate. All the components of the health-care agent are crushed to 200 meshes and are uniformly mixed. In a feed processing process,the intestinal mucosa protective agent is used as an additive and is added according to the ratio of 0.1 percent to 0.2 percent to prepare functional feed. In a culture production process, the intestinal mucosa protective agent is fed for one period every 10 days from the last ten-day period of June to the last ten-day period of August every year. The intestinal mucosa protective agent is obtained from scientific experiment results and has scientific compatibility; an operation method is simple and convenient. The protective agent has a remarkable protection effect on intestinal mucosa of thepenaeus vannamei and can be used for remarkably reducing the occurrence rate of jejunum and empty stomach and white stool diseases of the penaeus vannamei and remarkably improving the culture economic benefits of the penaeus vannamei.

Description

technical field [0001] The invention belongs to the field of an animal intestinal mucosa protective agent, relates to Penaeus vannamei, in particular to an intestinal mucosa protective agent applied to Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three top varieties with the highest aquaculture output in the world, and it is also the prawn species with the largest aquaculture output in China. According to the data from the China Fisheries Yearbook in 2019, in 2017, 1.0808 million tons of Penaeus vannamei were cultured in seawater, and 1.0808 million tons were cultured in freshwater. Penaeus vannamei is 591,500 tons. In 2018, 1.1175 million tons of Penaeus vannamei were cultured in seawater and 642,800 tons were cultured in freshwater. Compared with 2017, the output of Penaeus vannamei in 2018 increased by 8.8 tons, a year-on-year increase of 5.26% . Nevertheless, the farming situation of Penaeus vannamei is not optimistic. Acute hepatopanc...
