Fermented-flavor environment-friendly small carp puffed slowly-sinking compound feed and preparation method thereof

Abstract

The invention discloses fermented-flavor environment-friendly small carp puffed slowly-sinking compound feed. The feed is prepared from, by weight, 20-25 parts of bean pulp, 5 parts of brown fishmeal, 20-25 parts of cottonseed meal, 20-27 parts of wheat, 10-15 parts of rapeseed meal, 10-15 parts of rice bran, 1-2 parts of mineral premix, 0.3-0.5 part of vitamin premix, 1.5-2 parts of monocalcium phosphate, 1.5-2.5 parts of fish oil, 1-2 parts of calcium propionate, 0.2-0.4 part of moringa seed, (1-3)*10<-6> parts of phytase and 0.2-0.5 part of Chinese herbal medicine additive. During preparation, the main raw materials are mixed evenly, fermented and then smashed, puffed, extruded and granulated to prepare the carp environment-friendly puffed slowly-sinking compound feed high in digestion and absorption rate. When carp is fed with the feed, water pollution can be reduced, the survival rate of carp is increased, feed cost is reduced, and raised fish is good in figure, high in disease resistance, delicious in meat and rich in nutrient and can have a health care effect on body health.

Description

technical field [0001] The invention relates to a feed for crucian carp, in particular to a fermented-flavor environment-friendly small crucian carp puffed slow-sinking compound feed and a preparation method thereof, which are fermented after being mixed with ingredients, and then subjected to processes such as puffing. Background technique [0002] With the increase of human demand for high-end aquatic products, crucian carp meat is delicious, flat in nature, and sweet in taste. Symptoms such as vomiting less milk, thirsty drinking water, small intestinal hernia and so on. Herring is the top-grade freshwater fish because of its fat and tender meat, delicious taste, and protein content higher than that of chicken. It is favored by everyone. The crucian carp breeding industry is developing rapidly. The current crucian carp breeding feed is mainly ordinary hard pellets. Either rapeseed meal, wheat and low-quality ordinary hard pellets are commonly used in breeding, resulting ...

AI Technical Summary

Problems solved by technology

The feed utilization rate is low and the feed coefficient is high, resulting in more residual bait deposition, resulting in eutrophication of the aquaculture water body, high nitrogen and phosphorus discharge, heavy water pollution, and fish prone to intestinal diseases, weak disease resistance, fish Diseases occur frequently, production decreases, and the cost of farming per unit of fish is also high

Ordinary puffed floating materials do not meet the feeding habits of crucian carp, so there is a problem that domestication is difficult and difficult to achieve

At present, there is no published feed for crucian carp fermented environmentally friendly puffed slow-sinking compound feed. This requires creative research and testing on raw material components, the content of each raw material component, and suitable production processes. Environmentally friendly and efficient crucian carp puffed slow-sinking compound feed with reasonable nutrition and low feed coefficient
