The invention relates to a feed for yellow croaker double spines and a preparation method thereof. The feed includes protein source raw materials, fat source raw materials, sugar source raw materials and auxiliary materials, and is characterized in that: the weight content of protein in the feed is 48.94%; The protein/fat mass ratio is 47/11, that is, the egg-to-energy ratio is 24.99mg/kJ; the auxiliary materials contain vitamin A 1774.19IU/kg, vitamin C 115.38mg/kg, vitamin E 65.83mg/kg, and phosphorus 1.01wt% , containing calcium, and the ratio of calcium to phosphorus is 0.892, the protein source raw material is selected from the group consisting of fish meal, casein, soybean meal and their mixtures; the fat source raw material is selected from the group consisting of fish oil, soybean oil and their mixtures; the sugar source raw material is Starch; auxiliary materials also include one or more of dextrin, microcrystalline cellulose, soybean lecithin powder, DL-methionine, choline chloride, and squid paste. The feed of the invention increases the weight gain rate and survival rate of the double-spinous yellowtail, contributes to the large-scale and intensive cultivation of the double-spinous yellowtail, can improve the bait source of the double-spinous yellowtail, and saves breeding costs. |
