Preparation and feeding methods of pellet feed for reproductive period of giant salamanders

Abstract

The invention belongs to the technical field of feed and especially relates to preparation and feeding methods of pellet feed for the reproductive period of giant salamanders. The pellet feed providedby the invention is prepared from fishmeal, sodium bicarbonate, yeast powder, a vitamin complex, mannose, spirulina and a traditional Chinese medicine additive as raw materials, and contains comprehensive nutrients by reasonable collocation, thereby meeting the nutrient requirements of male and female giant salamanders in the reproductive period, improving the immune functions of the giant salamanders in the reproductive period, reducing the disease rate, promoting the absorption function of the gastrointestinal tracts on the feed, and especially improving the semen quality and activity of the male giant salamanders in the reproductive period.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a method for preparing and feeding granular feed for giant salamanders during the breeding period. Background technique [0002] The Chinese giant salamander is a unique species in China. Because it sounds like a baby crying, it is also commonly known as the giant salamander. It is a national second-class protected animal and belongs to the vertebrate phylum, amphibian class, urology, and Cryptobranchidae. The Chinese giant salamander is mainly distributed in Guizhou and Sichuan. , Hubei, Hunan, Shaanxi, Henan, Guangxi and other 17 provinces and autonomous regions; the Chinese giant salamander is rich in protein, comprehensive in amino acid composition, and has high medicinal value and scientific research value; The destruction of the environment, artificial overfishing and poaching have caused a sharp decline in wild giant salamanders; based on the research results of the ecologica...

[0002] The Chinese giant salamander is a unique species in China. Because it sounds like a baby crying, it is also commonly known as the giant salamander. It is a national second-class protected animal and belongs to the vertebrate phylum, amphibian class, urology, and Cryptobranchidae. The Chinese giant salamander is mainly distributed in Guizhou and Sichuan. , Hubei, Hunan, Shaanxi, Henan, Guangxi and other 17 provinces and autonomous regions; the Chinese giant salamander is rich in protein, comprehensive in amino acid composition, and has high medicinal value and scientific research value; The destruction of the environment, artificial overfishing and poaching have caused a sharp decline in wild giant salamanders; based on the research results of the ecological habits and biological characteristics of wild giant salamanders, artificial breeding and industrial farming of giant salamanders have been successful, and have shown huge economic and social benefits ; The pure natural bait nutrient supply mode can no longer meet the development situation of giant salamander artificial breeding; therefore, the development of artificial compound feed suitable for the growth and reproduction of giant salamander has become one of the important ways of large-scale culture of giant salamander; however, most of the feed in the prior art The unreasonable nutrient mix and the low feed utilization rate lead to frequent use of feed during the breeding process, which increases the cost of breeding; while during the breeding period of giant salamanders, the immunity is weak, and the unreasonable feed mix can easily lead to enteritis, Symptoms such as ascites disease, hepatobiliary syndrome, etc., which in turn cause the giant salamander to be hindered in reproduction and unable to breed offspring
