Special phagostimulant of Chinese softshell turtles and application of phagostimulant

Abstract

The invention discloses a special phagostimulant of Chinese softshell turtles and application of the phagostimulant. The phagostimulant is characterized by consisting of the following components in percentage by weight: 3-6 percent of methionine, 3-6 percent of lysine, 3-6 percent of arginine, 3-6 percent of alanine, 3-6 percent of glycine, 5-15 percent of dimethylpropiothetin, 5-10 percent of daghestan sweetclover herb, 5-10 percent of ferula asafetida and 40-60 percent of squid liver powder. One to two percent of phagostimulant is added into a commercially available compound feed; compared with a feed without the phagostimulant disclosed by the invention, the feed with the phagostimulant disclosed by the invention has the advantages that the ingestion time is shortened by 0.5-1 hour, the ingestion amount is increased by 5-10 percent, the corrosion ratio of the feed is reduced by 15-30 percent, the bait coefficient is reduced to be lower than 1.5, the nitrogen and phosphorus content of water is reduced by 15-20 percent, and the problems of drug residues and the like are solved.

Description

technical field [0001] The invention relates to a feed additive for aquatic animals, in particular to a special food attractant for Chinese soft-shelled turtle and its application. Background technique [0002] Chinese soft-shelled turtle ( Pelodiscus sinensis , soft-shelled turtle) are omnivorous and carnivorous animals, especially like foods with high animal protein content, such as: fish, shrimp, snails, aquatic insects and animal carcasses, etc., have a wide appetite, strong digestion ability, and are not easy to cause disease when eating rancid food. In natural waters, due to its slow movement, when animal food resources are insufficient, it also eats plant foods such as algae, aquatic plants, and crops. Traditional breeding baits mainly include: chilled fish, snails, bean cakes, broken corn kernels, etc. With the popularization of artificial full-price compound feeds, artificial compound feeds for soft-shelled soft-shelled turtles are gradually accepted by farmers du...

AI Technical Summary

Problems solved by technology

The breeding of Chinese soft-shelled turtle and the research and development of artificial compound feed started relatively late. So far, there have been few studies on the food attractant of Chinese soft-shelled turtle. The food attractant formula for fish, in terms of its composition, is not completely suitable for the feeding habits of Chinese soft-shelled turtles

At present, there are no relevant research reports on the special food attractant for Chinese soft-shelled turtle at home and abroad.
