Feed capable of promoting growth and resisting stress for longsnout catfish in later culture stage

Abstract

The invention discloses a feed capable of promoting growth and resisting stress for longsnout catfish in the later culture stage. The feed comprises, by weight, 12-20 parts of cicada pupa meal, 5-16 parts of bean pulp, 10-20 parts of buckwheat powder, 8-16 parts of walnut powder, 6-12 parts of spirulina meal, 8-16 parts of green vegetable leaf, 4-8 parts of flour, 4-12 parts of modified casein, 3-7 parts of fish oil, 0.5-1.2 parts of choline chloride, 0.5-1.2 parts of bile acid, 1-2 parts of monocalcium phosphate, 0.1-0.25 part of ferric sulfate, 0.3-0.65 part of copper lysinate, 0.2-0.4 part of manganese methionine, 0.2-0.6 part of zinc sulfate, 0.3-0.7 part of magnesium sulfate, 0.2-0.4 part of arginine, 0.2-0.6 part of glutamic acid, 1-2 parts of glycine betaine, 1-3 parts of vitamin and 1-2 parts of Chinese herbal medicine. By the adoption of the feed, growth and development can be promoted, the anti-stress ability and immunity of longsnout catfish can be improved, and the situations of body surface hyperemia, transverse lodging and large-scale death of longsnout catfish between the later culture stage and market selling and transportation are avoided.

Description

technical field [0001] The invention relates to the technical field of catfish feed, in particular to a growth-promoting and stress-resistant catfish feed in the later stage of culture. Background technique [0002] The meat of catfish is tender and delicious, rich in nutrition, and the fish fat is thick, which can be processed into precious fish maw. For a long time, people have regarded catfish as a nourishing aquatic product, and it was still a tribute to the imperial court in feudal society. Before the 1970s, the output of catfish was completely dependent on river fishing. Since the 1980s, artificial breeding and breeding technology research on catfish has been carried out, and the technical problems of artificial breeding have been solved. However, during the late stage of catfish breeding to market sales and transshipment, the body surface of catfish is often congested, and serious injuries can be caused. Stress responses such as lateral lodging and mass death of catf...
