Feed additive for preventing and treating ascites disease of bullfrogs as well as preparation method and application thereof

Abstract

The invention relates to a feed additive for preventing and treating ascites disease of bullfrogs as well as a preparation method and application of the feed additive. The feed additive comprises the following components in parts by weight: 15-30 parts of fructus forsythiae, 15-30 parts of radix bupleuri, 1-2 parts of allicin, 2-4 parts of bile acid, 15-25 parts of lactobacillus acidophilus freeze-dried powder, 15-25 parts of bacillus subtilis freeze-dried powder and 10-20 parts of corn starch. According to the invention, allicin is compatible with forsythia suspensa and bupleurum chinense to enhance the drug effect, and bile acid is combined with forsythia suspensa and bupleurum chinense to more effectively improve the liver function and reduce the liver lesion probability; besides, the lactobacillus acidophilus and the bacillus subtilis are adopted, regulation and inhibition of flora in digestive tracts such as intestinal tracts are facilitated, pathogenic bacteria in water are inhibited, absorption of animals to nutrient substances is promoted, and the feed conversion rate is increased; finally, traditional Chinese medicines and beneficial bacteria are combined, so that side effects are avoided, ascites diseases can be prevented and treated. According to the invention, the feed coefficient is reduced, the weight gain rate is increased, the effects are remarkably enhanced through combination of the traditional Chinese medicines and the beneficial bacteria, and economic benefits are increased.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for preventing and treating bullfrog ascites disease and its preparation method and application. Background technique [0002] The bullfrog (Rana catesbeian) belongs to the class Amphibians, Anura, and Ranaidae. It is named for its sound like a cow. It is a large edible frog. The bullfrog is native to North America and Mexico. It was introduced into my country from Cuba in 1959. It is a high-protein, low-fat and low-cholesterol meat product. It has delicious taste, fast growth and strong environmental adaptability. Has a broad consumer market. In 2019, my country's bullfrog breeding output is close to 500,000 tons, and the direct sales output value exceeds 5 billion yuan per year. Bullfrog has become an important famous and special species in my country's aquaculture. [0003] In the process of bullfrog breeding, ascites disease is prone to occur in high temperature season, esp...

AI Technical Summary

Problems solved by technology

The pathogen of bullfrog ascites disease is mainly Aeromonas hydrophila, which has strong infectivity and is easy to break out in the whole pond, causing a large number of bullfrog deaths in a short period of time and causing serious economic losses

[0004] Usually, farmers will use sulfonamides or sandacin drugs for prevention and treatment. However, the existing drugs have no special effect on ascites disease. At the same time, due to the problems of drug resistance, drug residues affecting meat quality, high cost of drug use, and inconvenient operation, The industry urgently needs a green feed additive that can replace the use of antibiotics to solve the above problems
