Siniperca chuatsi feed phagostimulant and preparation method thereof

The invention discloses a siniperca chuatsi feed phagostimulant and a preparation method thereof. The siniperca chuatsi feed phagostimulant added to each kilogram of feed is prepared from the following raw materials by weight: 2.0g of animal liver extract, 0.2-0.5g of dimethyl-beta-propiothetin, 0.5-2.0g of trimetlylamine oxide, 0.2-0.5g of L-glycine, 20-25g of hypoxanthine nucleotide, 0.5-3.0g ofbetaine, 10-15g of L-alpha-alanine and 10-15g of cuttlefish viscera powder. The preparation method of the phagostimulant is as follows: taking the betaine, sequentially adding the animal liver extract, the dimethyl-beta-propiothetin, the trimetlylamine oxide, the L-glycine, the hypoxanthine nucleotide, the alanine and the cuttlefish viscera powder, conducting full uniform mixing once finishing adding one raw material, and finally conducting full uniform mixing. The phagostimulant is reasonable in formula, can improve the feeding rate, feeding-taming survival rate and weight gain rate of siniperca chuatsi, and can red
