Abstract

The invention relates to a bighead carp feed and a preparation method thereof. The bighead carp feed comprises the following main raw materials and rough components: 10-12% of soy bean meal, 15-18% of cottonseed meal, 18-22% of rapeseed meal, 20% of wheat middlings, 15% of oil bran, 5% of imported fish meal, 2% of monocalcium phosphate, 2% of compound premix, 1-2.5% of plant oil and 5-10% of other raw materials (bentonite, zeolite powder and the like) playing a role of filling. The preparation method comprises the steps of ultramicro grinding, preparing, blending, extruding and cooling and mixing. The bighead carp feed has the following characteristics: the grinding fineness is good, the sinking speed is low, the bighead carp utilization ratio is high, the fish school growth speed is high, the cultured bighead carp has shape, color and mouthfeel the same as the bighead carps in the natural water body and has excellent quality, and the bighead carp feed can effectively improve the culture benefits and simultaneously conforms to the requirements for ecologically healthy culture and environmental protection.
