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

Abstract

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.

Description

technical field [0001] The invention relates to a loach feed, in particular to an anti-resistance loach compounded hard particle feed and a preparation method thereof after being micronized and aged at a high temperature. Background technique [0002] With the application of loach breeding and supporting technology, the aquaculture industry of loach is developing rapidly, and the consumption of aquatic products is gradually increasing with the improvement of people's living standards. As people pay more and more attention to health, the demand for aquatic products such as loach Rapeseed meal, wheat and low-quality ordinary hard pellets are commonly used in the current farming of loach and other freshwater fish feeds. The cost per unit of fish farming is high, the utilization rate is low, there are many residual baits, and the feed coefficient is greater than 1.8-2.5 . For the hard loach pellets of ordinary technology, the utilization rate of fish feeding is only about 55-75...

AI Technical Summary

Problems solved by technology

Low feed utilization rate and high feed coefficient will lead to more residual bait deposition, resulting in eutrophication of aquaculture water, high nitrogen and phosphorus discharge, heavy water pollution, frequent fish diseases, decreased survival rate, and reduced production , the cost of farming per unit of fish is also higher

There is no antibiotic-free micropowder prepared for loach and the hard pellet feed produced by high-temperature granulation. This requires creative research and experiments on the raw material components, the content of each raw material component, and suitable production processes. Feed on loaches, and the nutrition is reasonable, the feed coefficient is small, the compound hard pellet feed of mature non-resistant loaches
