Problems solved by technology

[0003] Practice has shown that in the breeding process, due to the double influence of environmental factors and fish intestinal tissue physiological factors, bacterial enteritis has become the second largest factor threatening tilapia farming after streptococcal disease; The fish disease spreads rapidly, the mortality rate is high, and often causes serious economic losses in farming

Embodiment 1

[0017] A feed additive for preventing tilapia enteritis, comprising 10% of citric acid, 3% of bile salt, 4% of zeolite powder, 0.1% of sodium chloride, 0.5% of glucose by weight percentage, and also includes Streptococcus lactis and Lactobacillus , Bacillus licheniformis, wherein, the content of the lactis streptococcus is 1 × 10 13 individual / g, the content of Lactobacillus is 1×10 13 individual / g, the content of Bacillus licheniformis is 1×10 8 pieces / g, and the rest is corn cob powder. In this example, the Streptococcus lactis, Lactobacillus and Bacillus licheniformis were all isolated from the intestinal content flora of tilapia.

[0018] The feed additive for preventing tilapia enteritis is obtained by pulverizing the above-mentioned raw materials and mixing them according to the ratio by using a conventional method.

Embodiment 2

[0020] A feed additive for preventing tilapia enteritis, comprising 12% of citric acid, 2% of bile salt, 2% of zeolite powder, 0.2% of sodium chloride, and 1% of glucose by weight percentage, and also includes Streptococcus lactis and Lactobacillus , Bacillus licheniformis, wherein, the content of the lactis streptococcus is 1 × 10 14 individual / g, the content of Lactobacillus is 1×10 14 individual / g, the content of Bacillus licheniformis is 1×10 9 pieces / g, and the rest is corn cob powder. In this example, the Streptococcus lactis, Lactobacillus and Bacillus licheniformis were all isolated from the intestinal content flora of tilapia.

[0021] The feed additive for preventing tilapia enteritis is obtained by pulverizing the above-mentioned raw materials and mixing them according to the ratio by using a conventional method.

Embodiment 3

[0023] A feed additive for preventing tilapia enteritis, comprising 15% of citric acid, 1% of bile salt, 1% of zeolite powder, 0.3% of sodium chloride, 2% of glucose by weight percentage, and also includes Streptococcus lactis and Lactobacillus , Bacillus licheniformis, wherein, the content of the lactis streptococcus is 1 × 10 15 individual / g, the content of Lactobacillus is 1×10 15 individual / g, the content of Bacillus licheniformis is 1×10 10 pieces / g, and the rest is corn cob powder. In this example, the Streptococcus lactis, Lactobacillus and Bacillus licheniformis were all isolated from the intestinal content flora of tilapia.

[0024] The feed additive for preventing tilapia enteritis is obtained by pulverizing the above-mentioned raw materials and mixing them according to the ratio by using a conventional method.

Abstract

The invention provides a feed additive for preventing tilapia enteritis. The feed additive comprises citric acid, bile salt, zeolite powder, sodium chloride, glucose, lactic streptococci, lactic acid bacillus and bacillus licheniformis. By improving the thickness of intestinal mucosae, the intestinal nonspecific physical defense function is enhanced, reproduction of intestinal harmful microorganisms is inhibited, release of harmful substances is promoted, the capacity of fish bodies for resisting enteritis caused by invasion of extraneous pathogenic harmful organisms is improved, and therefore the tilapia enteritis and death caused by the tilapia enteritis are prevented.

Description

【Technical field】 [0001] The invention relates to a fish feed additive, in particular to a feed additive for preventing tilapia enteritis, and belongs to the field of aquatic feed additives. 【Background technique】 [0002] Tilapia is a kind of economic fish widely cultivated in South China, with an annual output of about 1.5 million tons, which has made an important contribution to stimulating domestic demand for aquatic products and driving the export of aquatic products in my country. The tilapia intestine is an important place for absorbing nutrients, and the intestinal tissue is composed of mucosal layer, submucosa layer, muscular layer and adventitia layer. Among them, the mucosal layer consists of intestinal villi and crypts, which not only have the function of absorbing nutrients, but also have special secretion functions, especially in regulating metabolism and maintaining the relative stability of the internal and external environment of the body.
