Problems solved by technology

However, if too much feed is fed, catfish cannot finish eating and produce a large amount of residual feed. Residual feed is one of the main causes of water quality deterioration, manifested as an increase in ammonia nitrogen and a decrease in oxygen content in the water body, especially in an opaque greenhouse. This effect is more obvious, and the deterioration of water quality has a significant impact on the growth of catfish

Abstract

The invention discloses a preparation method of a Leiocassis longirostris feed for avoiding deterioration of water quality, comprising the following steps: stirring etherified starch, fibroin, N-methylol acrylamide and water, adding N, N-methylene bisacrylamide and polyethylene glycol and continuously stirring, adding sodium persulfate, and carrying out ultrasonic treatment to obtain starch complex; uniformly mixing blood worm powder, sesame meal, fly maggot protein powder, rapeseed meal, sorghum powder, shell powder, water hyacinth dry powder and mulberry leaves, adding water and boiling, filtering, drying and crushing to obtain a prefabricated material; adding a pretreatment material, zeolite powder, calcium hydrogen phosphate, phytase, cellulase, yeast powder, L-tyrosine, allicin, a phagostimulant, honeysuckle, licorice, coptis chinensis and cortex phellodendri into the prefabricated material and uniformly mixing, pelletizing, drying, and screening to obtain the Leiocassis longirostris feed for avoiding deterioration of water quality. The feed can help raise disease resistance of Leiocassis longirostris and has good anti-stress effect; and absorption of nutrients in the feed ispromoted. Meanwhile, the feed is not easy to disperse in water, thus avoiding deterioration of water quality.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a method for preparing catfish feed that avoids deterioration of water quality. Background technique [0002] There is a close relationship between feed and water quality. Catfish are greedy for good food and eat a lot. However, if too much feed is fed, catfish cannot finish eating and produce a large amount of residual feed. Residual feed is one of the main causes of water quality deterioration, manifested as an increase in ammonia nitrogen and a decrease in oxygen content in the water body, especially in an opaque greenhouse. This effect is more obvious, and the deterioration of water quality has a significant impact on the growth of catfish. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing catfish feed that avoids water quality deterioration. The resulting feed can i...
