Non-antibiotic micropowder aged compound hard particle feed for loaches and preparation method thereof

The invention discloses a non-antibiotic micropowder aged compound hard particle feed for loaches, which is prepared through the following steps: preparing raw materials such as bean meal, red fish meal, spray-dried blood cell meal, cottonseed meal, wheat, rapeseed meal, peanut meal, rice bran, mineral premix, calcium dihydrogen phosphate, calcium propionate, health-care liquid and the like, performing micropowder processing, and performing high-temperature pelletization to obtain the high-digestibility non-antibiotic compound hard particle feed for loaches. The feed has the advantages of high feed utilization rate, high anti-nutritional factor destruction rate, high in-water stability, low feed coefficient and low morbidity rate. When loaches are fed with the feed, water pollution can be reduced, the loach survival rate can be increased, and the feeding cost can be lowered. The adult loaches are favorable in shape, palatable in flesh and abundant in nutrition, and can achieve health-care effect on human health.
