The invention relates to a feed for grass carp. The feed is mainly prepared from the following raw materials in percentage by mass: 30-35% of bean pulp, 0.3-0.4% of fine ground limestone, 8-10% of cottonseed meal, 10-15% of domestic fish meal, 2-3% of bentonite, 8-10% of rice bran meal, 10-15% of flour, 10-12% of high protein flour, 0.1-0.2% of lysine, 0.1-0.2% of vitamin C, 0.5-0.7% of an adhesive, 0.02-0.05% of bacillus subtilis, 0.3-0.5% of a fish premix and 0.3-0.5% of a Yikang XP-aquatic product. The feed provided by the invention contains various energy, proteins and amino acid substances required by growth of fishes and is balanced in proportion. By adding the Yikang XP-aquatic product, the feed digestibility utilization ratio is improved and the digestion-absorption function and the immune coordinating capacity of the fishes are maintained and improved. By adding VC, the disease resistance of grass carp is improved. By adding bacillus subtilis to adjust the microecological balance of the intestinal tract of the grass carp, the feed utilization ratio is improved. |
