Special feed formulation for giant salamanders

Abstract

The invention relates to the field of fish feed, in particular to special feed formulation for giant salamanders. The special feed formulation is composed of, by weight, 20-30 parts of sorghum, 45-60 parts of meat meal, 1-3 parts of pollen, 2-3 parts of Radix Astragali, 0.05-0.1 part of Ganoderma, 4-6 parts of Rhizoma Dioscoreae, 10-15 parts of sweet potatoes, 5-10 parts of peeled soybean meal, 15-20 parts of egg yolk powder, 3-4 parts of complex vitamins, 1-2 parts of mineral substances, 0.03-0.04 part of aspartic acid, 0.04-0.06 part of glutamic acid, 0.02-0.03 part of lysine, 0.02-0.03 part of leucine, 0.01-0.02 part of tryptophan and 0.35-0.4 part of salt. The special feed formulation for the giant salamanders has the advantages that by scientific matching according to actual nutritional requirements of the giant salamanders, autoimmunity of the giant salamanders can be improved, morbidity of the giant salamanders is reduced, and growth cycle of the giant salamanders can be shortened.

Description

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

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

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