A carp feed for improving muscle quality and a preparation method thereof belong to the technical field of feed preparation. The purpose of the present invention is to solve the problems of high price of protein source in the existing carp feed, resulting in low cost of carp culture. According to the dry matter calculation, the feed includes 50%-60% chlorella, 2.8%-12.8% according to the mass percentage. Cellulose, 29%-31% corn starch, 1% premix, 0.2% choline chloride, 3% Ca(H 2 PO 4 ) 2 , 2% sodium carboxymethyl cellulose; the method is: The chlorella powder, cellulose, corn starch, premix, choline chloride, Ca(H 2 PO4) 2 and sodium carboxymethyl cellulose are pulverized and uniformly stirred into mixed powder; Machine rolling feeding, steam conditioning, extrusion, drying and cooling through twin-screw extruding pellet machine to obtain pellets. The soybean meal feed completely replaced by chlorella in the present invention can significantly improve the growth performance and feed utilization efficiency of the carp, and also can obviously improve the muscle elasticity of the carp to make it more chewy and taste better. |
