Fermentation aroma type antibiotic-free enteritis-preventing ctenopharyngodon idellus adult fish formula hard-particle feed and preparation method thereof

Abstract

The present invention discloses a fermentation aroma type antibiotic-free enteritis-preventing ctenopharyngodon idellus adult fish formula hard-particle feed, wherein soybean meal, lutjanus erythopterus powder, cottonseed meal, wheat, rapeseed meal, ramie fiber, Chinese herb powder, a feed additive, a mineral premixed material, calcium dihydrogen phosphate, calcium propionate and other raw materials are fermented, the fermented materials are dried, and crushing and low temperature granulation are performed to obtain the high digestion rate and high absorption rate fermented antibiotic-free ctenopharyngodon idellus adult fish formula hard-particle feed. According to the present invention, the feed has advantages of high feed utilization rate, high anti-nutrition factor damage rate, high stability in the water and low feed coefficient; and with the application of the feed to feed the ctenopharyngodon idellus, the advantages of health fish intestinal tract, water pollution reducing, ctenopharyngodon idellus adult fish survival rate improving, feeding cost reducing, good breeding fish shape, strong disease resistance, low incidence, effective prevention of the occurrence of stress enteritis, prevention of group infectious diseases, delicious fish meat, rich nutrition and human health care can be provided.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to a fermented-flavor type non-antibiotic-resistant enteritis-resistant grass carp adult fish mixed hard pellet feed which is fermented and processed and granulated at low temperature and a preparation method thereof. Background technique [0002] With the increase of the three-high population, people pay more attention and pursuit of health, and the demand for aquatic products is increasing day by day. The aquaculture industry of grass carp develops rapidly, becoming a typical representative of freshwater fish production and rapid weight increase. Grass carp farming Therefore, it is increasingly favored by fishermen. However, poor disease resistance and prone to enteritis exist in grass carp farming, which affects the survival rate and profitability of grass carp. Enteritis has become a major worry for farmers. At present, freshwater fish such as grass carp are generally fed with rapeseed ...

AI Technical Summary

Problems solved by technology

Feed utilization rate is low, intestinal inflammation is induced, and feed coefficient is large, which will lead to more residual bait deposition, resulting in eutrophication of aquaculture water, high nitrogen and phosphorus discharge, heavy water pollution, and weak disease resistance of fish , fish diseases occur frequently, the survival rate decreases, the output decreases, and the cost of farming per unit of fish is also high
