Mixed feed suitable for grass carp in Ningxia regions and preparation method of mixed feed

Abstract

The invention relates to mixed feed suitable for grass carp in Ningxia regions and a preparation method of the mixed feed. The feed is mixed feed for grass carp which is prepared from the following raw materials of flour, bran, rice bran, bean pulp, cottonseed meal, degossypolized cottonseed protein, DDGS, rapeseed meal, fish meal, corn gluten meal, soybean oil, monocalcium phosphate, bentonite, zeolite powder, choline chloride, sodium chloride, compound premix feed for grass carp, L-ascorbic acid-2-phosphate and a micro-ecological preparation. The mixed feed has an excellent facilitating effect of improving the breeding level of grass carp in northwest regions. Meanwhile, high-quality feed raw materials and intestinal regulation micro-ecological preparations are further selected, so that the production process is continuously improved, and the feed has obvious effects of improving the food consumption of the grass carp, increasing the daily gain of the grass carp and improving the feed conversion ratio.

Description

technical field [0001] The invention relates to the technical field of breeding feed, in particular to a compound feed suitable for grass carp in Ningxia area and a preparation method thereof. Background technique [0002] Grass carp is one of the four major fish species in my country. It has a long history of breeding and is cultivated in a wide range of areas.

AI Technical Summary

Problems solved by technology

Fatty liver of grass carp will occur after feeding. In severe cases, large areas of grass carp will die. A large part of the high-energy and high-egg feed will not be eaten by grass carp, but will enter the water body to pollute the water quality, resulting in high ammonia nitrogen and nitrite values ​​in the water body.

Grass carp that have grown in this water environment for a long time have poor physical fitness, and the fish body turns red when they come out, and they are not resistant to transportation or die in large numbers during transportation.
