Feeds for freshwater fish

Abstract

The invention discloses feeds for freshwater fish. The feeds comprise the following raw materials in parts by weight: 20 to 40 parts of corns, 3 to 6 parts of bran, 10 to 15 parts of barley, 12 to 16 parts of soybean cakes, 2 to 5 parts of silkworm chrysalis, 3 to 5 parts of peanut vines, 3 to 10 parts of walnut powder, 2 to 8 parts of bone meal, 0.2 to 0.8 part of baking powder, 4 to 7 parts of salt, 0.1 to 0.3 part of 52 percent zinc sulfate, 0.2 to 0.4 part of ferric citrate and 0.3 to 0.5 part of manganese sulfate. According to the feeds, corn meal, which the freshwater fish like, is taken as a raw material, and is mixed with bran, buckwheat shells, peanut vines, walnut powder and bone meal, so that the feeds are comprehensively nutritional, proteins, vitamins and salts, which are required by the growth of the freshwater fish, can be supplemented, the physical quality of the freshwater fish can be enhanced, the immune system can be improved, the physique can be strengthened, the disease resistance can be improved, the appetite of the freshwater fish can be improved, and high growth speed and delicious meat can be ensured.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to a freshwater fish feed. Background technique [0002] The research on feed for freshwater fish farming in my country started in the 1980s, and it has been used in all directions. In the entire feed industry, feed for freshwater fish farming only accounts for 6-7% of the total feed, and there is still a lot of development potential, but At present, the vast majority of professional breeding households use premixed feed for feeding when they are breeding. The protein and vitamin nutrition are not comprehensive, and they cannot meet the nutrient needs of their growth stage, resulting in problems such as susceptibility to disease and slow growth. However, pure mineral supplementation The material is not enough, mainly need to add a certain amount of salt, otherwise there will be a lack of appetite and low fertility, which may bring great economic losses to the farmers.
