Compound feed capable of improving anti-stress capacity of fancy carps and preparation method of compound feed

Abstract

The invention relates to a compound feed capable of improving the anti-stress capacity of fancy carps and a preparation method of the compound feed. The feed comprises the following components in percentage by mass: 1%-1.5% of a fish premix, 0.2%-0.4% of choline chloride, 0.01%-0.04% of bile acid, 5%-15% of mixed meal, 10%-20% of bran residues, 3%-8% of defatted soy flour, 3%-10% of imported fish meal, 5%-10% of spirulina powder and 10%-20% of dried marine algae powder. According to the compound feed disclosed by the invention, necessary trace elements and vitamins are complemented in the fish premix, and in addition, the compound feed is also rich in anti-stree substances such as vitamin C and vitamin E, so that the anti-stress capacity and the immunity of pelteobagrus fulvidraco can be quickly improved, and the growth of the pelteobagrus fulvidraco is promoted; the soybean meal, the mixed meal, the bran residues and the like are added, so that the energy of the feed is increased; the fancy carps which are fed with the compound feed disclosed by the invention can safety live in the winter, and have the characteristics of being resistant to fishing, resistant to low oxygen, resistant to transportation and the like.

Description

technical field [0001] The invention relates to the technical field of feed for ornamental fish breeding, in particular to a compound feed for improving the anti-stress ability of koi fish and a preparation method thereof. Background technique [0002] Koi is a high-end ornamental fish species with high economic value. Usually, the price of a fish is several hundred to several thousand yuan. The body surface of the dorsal fin and caudal fin scales is congested, and in severe cases, the koi fish will fall laterally and die in large numbers and other stress reactions. Cause ornamental value decline and serious economic loss. Contents of the invention [0003] The present invention aims to solve the deficiencies of the prior art, and provides a special anti-stress feed for koi fish that is fed 7-10 days before the koi fish come out of the pond, so as to enhance the fish's physique and anti-stress ability in a short time, reduce the Losses during out pond and transshipment. ...
