A fermented anti-resistant crucian carp small fish compounded hard pellet feed and its preparation method

Abstract

The invention discloses a fermented non-resistant crucian carp small fish mixed with hard pellet feed, which is prepared by adding soybean meal, red fish meal, blood globulin powder, cotton meal, wheat meal, rapeseed meal, rice bran, mineral premix and calcium dihydrogen phosphate , calcium propionate, health care liquid and other raw materials are mixed and fermented, dried, crushed and granulated at low temperature to obtain a high digestion and absorption rate crucian carp and small fish fermented antibiotic-free compound hard pellet feed. This feed has high feed utilization rate and anti-nutritional factors. It has the advantages of high destruction rate, high stability in water and small feed coefficient. Feeding crucian carp with this feed can reduce water quality pollution, improve the survival rate of crucian carp, reduce the incidence of disease, and reduce the cost of feeding. Moreover, the raised fish have good body shape, delicious meat and rich nutrition, which can play a role in health care for human health.

Description

technical field [0001] The invention relates to a feed for crucian carp, in particular to a fermented non-resistant crucian carp small fish compounded hard pellet feed with a fermentation treatment process and low-temperature granulation and a preparation method thereof. Background technique [0002] With the application of crucian carp breeding and supporting technology, the aquaculture industry of crucian carp 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 crucian carp Rapeseed meal, wheat and low-quality ordinary hard pellets are generally used for feeding freshwater fish feed such as crucian carp. 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 . For the hard pellets of crucian carp and small ...

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

At present, there is no hard pellet feed produced by fermenting antibiotic-free feed for small crucian carp and granulating at low temperature. This requires creative research and testing on raw material components, the content of each raw material component, and suitable production processes. It is suitable for crucian carp feeding, and the nutrition is reasonable, and the fermented non-resistant crucian carp with a small feed coefficient is combined with hard pellet feed
