Abstract

The invention relates to feed and a preparation method thereof, in particular to a puffing feed for preventing whitening of black carp body color and a preparation method of the feed. The puffing feed comprises the following components by weight: 7-15% of fish meal, 15-30% of peeled bean pulp, 10-20% of rapeseed dreg, 1-5% of squid paste, 6-12% of meat and bone meal, 3-6% of beer yeast, 2-5% of pine needle meal, 3-7% of robinia pseudoacacia leave powder, 2-6% of seaweed meal, 0.1-0.2% of L-ascorbate-2-phosphate, 0.15-0.65% of choline chloride, 3-7% of corn protein powder, 15-25% of flour, 1-2% of soya-bean oil, 1-2% of monocalcium phosphate and 1-2% of fish pre-mix compound. The preparation method of the feed comprises the following steps: 1) weighting the components; 2) mixing uniformly and crushing; 3) introducing steam into a conditioner for conditioning, and carrying out pelletizing in an extrusion puffing pelletizer; and 4) drying. The feed has the advantages of being complete innutrition, and capable of being digested and absorbed easily, promoting deposition of fish organism pigments, and preventing body color change; and the puffing feed is good in stability in water, andhigh in digesting efficiency, and reduces the feed waste.

Description

technical field [0001] The invention relates to a feed and a preparation method thereof, in particular to an extruded feed for preventing herring from turning white and a preparation method thereof. Background technique [0002] Herring (Mylopharyngodon piceus), belonging to Cypriniformes, Cyprinidae, and Mylopharyngodon, also known as Wuqing, Qingkun, Qingwan, and Luosiqing, is one of the four famous domestic fish in my country. Because of its large size, rapid growth, fat and tender meat, few thorns in the meat, and high nutritional value, it is regarded as a high-quality edible fish and is popular among farmers and consumers. [0003] Wild herring has a blue-black body, a darker back, off-white belly, and black fins. In recent years, with the extensive use of artificial compound feed for breeding, the phenomenon of whitening or black and white variegated body color of fish often occurs, which seriously affects the market share of commercial fish. Herring feed is one of t...
