Fermented non-tolerant bleeding-preventing hard granular compound juvenile parabramis pekinensis feed and preparation method thereof

Abstract

The invention discloses a fermented non-tolerant bleeding-preventing hard granular compound juvenile parabramis pekinensis feed which has high digestibility and is prepared from soyabean meal, red fish meal, cottonseed meal, wheat, rapeseed meal, ramine fiber, herbal powder, a mineral premix, calcium dihydrogen phosphate, calcium propionate and other raw materials through fermentation, drying, crushing, and granulation at low temperature. The fermented non-tolerant bleeding-preventing hard granular compound juvenile parabramis pekinensis feed has the advantages of high feed utilization rate, high resistance to nutritional factor destruction, high stability in water and low feed coefficient; when parabramis pekinensis is fed with the fermented non-tolerant bleeding-preventing hard granular compound juvenile parabramis pekinensis feed, water pollution can be reduced, the survival rate of the juvenile parabramis pekinensis is improved, and the feeding cost is reduced; farmed juvenile parabramis pekinensis is good in body shape, high in disease resistance and low in disease rate, and stress bleeding can be effectively prevented; the meat is delicious and the nutrition is rich, so that a health-care effect on human health can be achieved.

Description

technical field [0001] The invention relates to a feed for bream fish, in particular to a fermented-flavor type non-antibiotic and anti-bleeding juvenile bream feed mixed with hard pellets and a preparation method thereof. Background technique [0002] With the increase of human demand for aquatic products, the aquaculture industry of bream has developed rapidly, and the aquaculture of bream has been increasingly favored by fishermen. However, at present, there are generally poor disease resistance of fish in aquaculture of bream, and the fish are prone to stress. Phenomena such as bleeding and hairing exist, which affect the appearance and price of bream, and become a major worry for farmers. Rapeseed meal, wheat and low-quality ordinary hard pellets are commonly used in the current breeding of freshwater fish feed such as bream. The cost per unit of fish farming is high, the utilization rate is low, there are many residual baits, the waste of feed is large, and the feed co...

AI Technical Summary

Problems solved by technology

The feed utilization rate is low and the 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, weak disease resistance of fish, and frequent occurrence of fish diseases , the survival rate decreases, the output decreases, and the cost of farming per unit of fish is also high

At present, there is no hard pellet feed produced by low-temperature granulation for juvenile bream fermented flavor-free anti-bleeding feed. This requires creative research and research on raw material components, the content of each raw material component, and suitable production processes. Only after the experiment can we get the fermented-flavor type non-antibiotic and anti-bleeding bream compound hard pellet feed suitable for bream feeding, with reasonable nutrition and low feed coefficient
