Micropterus salmonides compound feed and preparation method thereof

Abstract

The invention relates to micropterus salmonides compound feed and a preparation method thereof and belongs to the technical field of feed processing. The compound feed is prepared from the following components in parts by weight: 300-400 parts of fish meal, 200-300 parts of soybean meal, 100-250 parts of peanut meal, 200-250 parts of refined flour, 15-20 parts of monocalcium phosphate, 3-5 parts of choline chloride, 8-10 parts of a mineral substance premix, 2-4 parts of a vitamin premix, 1.5-2.5 parts of spiral seaweeds, 0.8-1.2 parts of silybum marianum and 0.8-1.2 parts of curcumin. The preparation method comprises the following steps: crushing the fish meal, the soybean meal and the peanut meal and sieving, and uniformly mixing with residual raw materials; then crushing and sieving the mixture in an ultrafine crusher; and after blending and granulating, drying, cooling, packaging and bagging to prepare the micropterus salmonides compound feed. With the adoption of the compound feed, the immunological competence of micropterus salmonides can be effectively improved and a physiological metabolism problem of the micropterus salmonides is solved; fatty livers are prevented so that the survival rate is improved; the feed can completely replace frozen and fresh seafood and can be used for feeding and culturing in a whole process, so that the pollution to a water body environment, caused by the fact that the frozen and fresh seafood is used for culturing, is solved; and the micropterus salmonides compound feed has relatively high economic benefits and remarkable social benefits.

Description

technical field [0001] The invention relates to a compound feed for California perch and a preparation method thereof, in particular to a sinking puffed compound feed for California perch that can completely replace chilled freshness and be fed and cultured throughout the whole process, and a preparation method thereof, belonging to the technical field of feed processing. Background technique [0002] California perch, formerly known as largemouth bass, belongs to Perciformes, sunfish family, and its origin is America. California sea bass is a high-protein meat, rich in vitamin A and vitamin B, nourishing the liver, kidney, spleen and stomach, and also effective for colds and coughs.

Problems solved by technology

With the continuous expansion of the scale of California perch farming and the continuous improvement of the degree of intensification, the farming method based on feeding fresh trash fish has been far from meeting the needs of its intensive farming; at the same time, due to the difficulty of storing fresh trash fish , easy to spoil, easy to spoil, breed bacteria, and cause eutrophication of aquaculture water. The market urgently needs high-efficiency, environmentally friendly high-quality compound feed for California sea bass

On the other hand, due to the unique characteristics such as the living habits and physiological mechanism of California perch, there are high requirements for the nutrition, crushing particle size, mixing uniformity, feed formability and water resistance of California perch feed. Some California bass feeds are difficult to meet these requirements

[0004] China invented "California perch extruded compound feed and its preparation method", application number 201410350061.0 discloses a formula of California perch compound feed with crude protein ≥ 48%, which has the characteristics of satisfying the strong appetite of California perch, but can improve the immunity of California perch Feed formula has not been reported yet
