Feed for grass carp

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a grass carp feed. Background technique [0002] Grass carp belongs to the genus Grass Carp of Cyprinidae Cyprinidae and has the advantages of fast growth, good meat quality, easy feeding and high yield, and is favored by fishermen and consumers. Grass carp, as one of the "four major fishes", is the largest economic fish in China. Grass carp aquaculture is developing rapidly in my country, but the quality of aquaculture products is not stable enough while the output is increasing. From the perspective of market demand, the color, taste, muscle quality, nutritional value, and flavor of farmed grass carp are the focus of consumers' attention. Ensuring the safety, hygiene and delicious taste of grass carp growing products is one of the important research directions of grass carp breeding in the future. At present, most grass carp feeds are unbalanced in the distribution of nu...

Problems solved by technology

At present, most grass carp feeds are unbalanced in the distribution of nutrients. During the breeding process, the nutritional imbalance will also cause fatty liver symptoms such as liver enlargement in grass carp, which seriously affects the economic benefits of grass carp farming.
