Mixed feed for improving streptococcus resistance of tilapia

Abstract

The invention relates to mixed feed for improving the streptococcus resistance of tilapia, and belongs to the technical field of fish feed. The mixed feed comprises fish meal, bean pulp, double-low rape seeds, DDGS, strong flour, degossypolized cottonseed protein, wheat bran, prickly ash seeds, soybean phosphatide oil, soybean oil, methionine, levan, vitamin premix, microelement premix, vitamin C phosphate, calcium dihydrogenphosphat, mildew preventive, choline chloride and vitamin E. According to the feed, the nutrition requirement of the tilapia is taken into full consideration, the levels of protein, energy and other nutrients of the feed are scientifically adjusted, and the feed utilization rate is improved for the tilapia. The vitamin E and the levan are added to the feed and cooperate with other raw materials so that the nonspecific immunity of the tilapia can be improved, and therefore the streptococcus resistance of the tilapia is improved. The morbidity and mortality of the diseases caused by streptococcus of tilapia are reduced, and economic loss caused by the diseases caused by streptococcus of tilapia is reduced.

AI Technical Summary

Problems solved by technology

[0003] At present, the tilapia farming mode in the main tilapia farming areas in western Guangdong (Yangjiang, Maoming, Zhanjiang) is still dominated by three-dimensional farming such as fish-pig polyculture and fish-duck polyculture. The water environment for tilapia farming is deteriorating day by day, the diseases of tilapia, especially streptococcal disease, are becoming more and more serious, and the farmers have suffered heavy losses

Judging from the incidence of streptococcal disease in tilapia in southern China in 2014, the incidence of streptococcal disease in tilapia in Maoming City reached 80%-90%, and the mortality rate was above 80%. The rate is 40-50%, causing great economic losses to farmers

[0004] A large number of antibiotics and chemical drugs are used in traditional disease prevention and control methods, which will cause a series of problems such as drug resistance and food safety. This method should be gradually eliminated
