Problems solved by technology

[0014] In order to overcome the problems existing in the prior art that excessive fertilization leads to eutrophication of the water body, easily causes water body pollution, slow growth period of fish, and causes a lot of waste of fish feed, etc., the present invention provides a special slow-sinking feed for bighead carp The preparation process, using the bighead carp feed of the present invention, has good crushing fineness, slow sinking speed, high utilization rate of the feed by bighead carp, is beneficial to the deposition of fish body protein, promotes the secretion of intestinal digestive enzymes, and has a fast growth rate. The size, taste and body color of the raised bighead carp are the same as those in natural water bodies. The meat is delicate and of high quality, which can effectively improve the economic benefits of farming, and at the same time minimize the pollution of the water environment, which is in line with the ecological and healthy farming and Environmental Protection Requirements

Abstract

The invention belongs to the technical field of the aquaculture feed and discloses a special slow sinking type feed for bighead. The slow sinking type feed comprises the following raw materials in percentage by weight: 25-35% of wheat flour, 0.5-9% of soya bean meal, 0-38% of casein, 8-10% of cottonseed meal, 8-12% of white fish meal, 1-2% of mineral premix, 1-3% of vitamin premix, 3-9% of soybean oil, 0.1-0.5% of choline chloride, 0.1-0.5% of salt, 2-3% of monocalcium phosphate, 0.05-0.2% of VC-lipid and 0.1-27% of cellulose powder. By researching the life habits of the bighead and the requirement amount of nutrient substances such as protein in the growth process, the slow sinking type feed applicable to bighead is researched; the slow sinking type feed is capable of promoting the growth of the bighead, facilitating the deposition of the ribosomal protein and facilitating the secretion of digestive enzymes in the enteric canal; after the slow sinking type feed is popularized, the slow sinking type feed has great social significance and economic significance.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a special slow-sinking feed for bighead carp and a preparation process thereof. Background technique [0002] Bighead carp ( Aristichthys nobles ) Taxonomically belongs to the Osteostichthyes, Cypriniformes, and Cyprinidae.
