Composite immune booster for loach and preparation method thereof

Abstract

The invention discloses a special-purpose composite immunopotentiator for loaches, and a preparation method of the special-purpose composite immunopotentiator. The composite immunopotentiator is prepared from the following components in parts by weight: 5-10 parts of garlic, 5-15 parts of Chinese rhubarb extracts, 1-5 parts of forsythia suspensa extracts, 1-5 parts of hickory exocarp crude extracts, 4-6 parts of bay leaves, 2-3 parts of sichuan chinaberry bark, 1-5 parts of alamo leaves, 5-10 parts of common ducksmeat herbs, 10-15 parts of haws, and 10-20 parts of table salt. The immunopotentiator is used as an additive to be matched with a conventional feed for use, so that the organism immunity of the loaches can be strengthened, and the resistance of the loaches can be improved; the immunopotentiator does not have toxic or side effects or untoward reaction; the immunopotentiator does not have bad influence on the tastiness of the feed, and the garlic, the Chinese rhubarb extracts, the forsythia suspensa extracts, the hickory exocarp crude extracts and the table salt are matched for use, so that saprolegniasis can be prevented all year round, and the attack rate can be reduced; the bay leaves, the sichuan chinaberry bark and the alamo leaves which are added can have the effects of eliminating and killing rotalia and gyrodactylus; the common ducksmeat herb extracts which are added can have better effect of preventing erythrodermatitis.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a special compound immune enhancer for loach and a preparation method thereof. Background technique [0002] Loach, also known as fish loach, has a slender body with a slightly cylindrical front section. The rear side is flat, the abdomen is round, and the head is small. Mouth small, inferior, horseshoe-shaped. Eyes small, no undereye thorns. 5 are required. The scales are extremely small, round and buried under the skin. The back of the body and both sides are gray-black, and there are many small black spots on the whole body. There are also many black spots on the head and each fin. The spots on the dorsal and caudal fin membranes are arranged in rows, and there is an obvious black spot at the base of the caudal peduncle. Loach is widely distributed in China, Japan, Korea, Russia and India along the coast of Asia. [0003] Loach is rich in protein, fat,...

Problems solved by technology

Therefore, natural fishing for loach is far from meeting the market demand, and artificial breeding of loach has begun to rise. Loach is often prone to various diseases and insect pests in the breeding process, especially saprolegniasis is easy to occur in March and April every year. It is common to have trichomonads, lingual cup worms, and third-generation parasites that cause death. Air bubble disease and red skin disease are also diseases that loaches are easy to infect during the breeding process. In the prior art, for common pests and diseases of loaches, usually after the pests are discovered Then use chemical agents to kill, instead of adopting preventive measures in advance. This kind of chemical agent killing can have a certain effect on mild pests and diseases, but for more ferocious pests and diseases, the effect is usually not very good. , will lead to the death of a large number of loaches, and bring certain economic losses to the farmers. This method of killing pests and diseases is only a temporary killing, and cannot be cured fundamentally. The occurrence of pests and diseases will lead to the death of loach. Decreased immunity and greatly increased mortality have seriously affected the growth rate of loach and the economic benefits of farming. How to prevent pests and diseases before they occur, improve fish resistance to the invasion of pests and diseases, and reduce the incidence of disease has become the key
