Fodder special for giant salamander

Abstract

The invention relates to the field of aquatic animal breeding and especially relates to a fodder special for giant salamander. The fodder is prepared from the following raw materials in parts by weight: 60-70 parts of fresh meat, 5-8 parts of sweet potato powder, 10-15 parts of puffing soybean meal, 7-11 parts of bean pulp, 1-2 parts of immune polysaccharides, 0.5-1 part of monocalcium phosphate, 1-1.5 parts of choline chloride, 1-3 parts of amino acid, 0.5-0.8 part of bletilla, 1-2 parts of polygonum aviculare, 1-2 parts of sedum sarmentosum and 3-4 parts of semen torreya. The formula is scientifically prepared according to the practical nutritional requirement of the giant salamander, the immunity of the giant salamander is promoted, the morbidity thereof is reduced and the growth period thereof is shortened.

Description

technical field [0001] The invention relates to the field of aquatic animal breeding, in particular to a special feed for giant salamanders. Background technique [0002] The giant salamander is commonly known as the giant salamander. The giant salamander is a national second-class protected aquatic wild animal. The wild giant salamander is already on the verge of extinction due to the harsh growth environment, insufficient food, and excessive hunting. The growth rate of wild giant salamanders is slow, and the growth cycle is long, which generally takes 3-5 years. According to existing regulations, only the second generation of giant salamanders can be eaten and traded. Therefore, in order to meet market demand, people began to artificially breed giant salamanders. [0003] How to improve the immunity, reduce the morbidity and shorten the growth cycle of artificially cultured giant salamanders has become a topic of most concern to farmers. In response to the above problems,...

Problems solved by technology

Due to the large breeding area, injection requires a lot of labor, and damage to fish is unavoidable

Soaking will consume a large dose of vaccine, and the vaccine will also cause huge economic losses due to the consumption and deposition of various substances in the breeding water

Therefore, the industrialized spraying method was introduced. It works on the same principle as the automatic injection machine, but it turns the injection into a vaccine spraying on the fish; while the oral vaccine, although the use is not limited by the time, place and the size of the fish, However, when the vaccine reaches the gastrointestinal tract, it is destroyed, which reduces the immune effect of the vaccine
