Low-fishmeal feed capable of improving protein content of black carp meat

Abstract

The invention belongs to the technical field of black carp breeding, and particularly relates to low-fishmeal feed capable of improving the protein content of black carp meat. The low-fishmeal feed comprises the following raw materials in parts by weight: 35-40 parts of peanut pulp, 5-10 parts of fishmeal, 8-12 parts of corn flour, 2-6 parts of beer yeast, 3-5 parts of high gluten flour, 3-5 partsof fish oil, 1-2 parts of compound fatty acid, 0.5-0.7 part of minerals and vitamins and 0.1-0.2 part of amino acid. Compared with the prior art, the low-fishmeal feed has the following advantages: through analysis on the nutritional components required by black carps, peanut meal is prepared into the peanut pulp to substitute for the fishmeal in quantity, the growth performance of fish bodies has no obvious change, and also the protein content in the black carp meat can be effectively improved, thereby reducing the cost of fish feed and simultaneously improving the quality of the fish meat;and the feed has good stability in water through sufficient conditioning.

Description

technical field [0001] The invention belongs to the technical field of herring culture, and in particular relates to a low-fishmeal feed for increasing the protein content of herring meat. Background technique [0002] Herring is one of the four traditionally farmed fishes in my country. In recent years, the aquaculture production of herring has developed very rapidly. It has the characteristics of fast growth, high output, and delicious meat. Large carnivorous fish mainly feed on natural shellfish such as snails. However, due to furniture polluted by water areas, natural shellfish resources are constantly decreasing, which seriously restricts the development of herring aquaculture, and the existing large-scale aquaculture in Focusing on the output while ignoring the quality of the herring, the meat quality of the herring is poor, and the protein content of the fish meat is reduced. By studying the feed components of the herring, it is found that changing a certain component i...

[0002] Herring is one of the four traditionally farmed fishes in my country. In recent years, the aquaculture production of herring has developed very rapidly. It has the characteristics of fast growth, high output, and delicious meat. Large carnivorous fish mainly feed on natural shellfish such as snails. However, due to furniture polluted by water areas, natural shellfish resources are constantly decreasing, which seriously restricts the development of herring aquaculture, and the existing large-scale aquaculture in Focusing on the output while ignoring the quality of the herring, the meat quality of the herring is poor, and the protein content of the fish meat is reduced. By studying the feed components of the herring, it is found that changing a certain component in the herring feed may have a certain impact on the body of the herring. At the same time, considering the shortage of fishmeal resources, it is considered to use other raw materials to replace fishmeal, but the growth performance of fish will be affected if the substitution amount is large. Therefore, how to improve the growth performance of herring and increase the protein in fish meat on the basis of reducing the amount of fishmeal Content has become a technical problem that needs to be solved urgently
