Fermented-aroma-type environment-friendly puffed slowly-sinking compound feed for culturing crucian and preparation method thereof

Abstract

The invention discloses a fermented-aroma-type environment-friendly puffed slowly-sinking compound feed for culturing crucian. A feed base material is prepared from, by weight, 20-25 parts of soybean meal, 20-25 parts of cottonseed meal, 20-27 parts of wheat, 10-15 parts of rapeseed meal, 15-20 parts of rice bran, 0.2-0.4 part of moringa seeds, 8-10 parts of vinegar residues, 1-2 parts of mineral substance premix, 0.3-0.5 part of vitamin premix, 1.5-2 parts of monocalcium phosphate, 1.5-3.5 parts of fish oil, 1-2 parts of calcium propionate, (1-3)*10<-6> part of phytase and 0.2-0.5 part of a Chinese herb additive. In the preparing process, main raw materials and accessory material are mixed evenly, the mixture is subjected to microbial fermentation, smashed, puffed and subjected to extrusion granulation, and then the environment-friendly puffed slowly-sinking compound feed, high in digestion and absorption rate, for crucian is obtained. By feeding crucian with the feed, water contamination can be reduced, the survival rate of crucian can be increased, feeding cost can be reduced, and meanwhile cultured crucian is good in bodily form, strong in disease resistance, and capable of providing delicious meat and achieving a healthcare effect on the human health.

Description

technical field [0001] The invention relates to a feed for crucian carp, in particular to a fermented-flavor environment-friendly crucian carp adult puffed slow-sinking compound feed and a preparation method thereof, which are fermented first, then compounded and mixed, and then subjected to puffing and other processes. 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 the production of environmentally friendly extruded slow-settling compound feed for crucian carp. This requires creative research and testing on the raw material components, the content of each raw material component, and suitable production processes. , and reasonable nutrition, low feed coefficient of environmentally friendly high-efficiency crucian carp puffed slow-sinking compound feed
