Health-care compound feed for enhancing anti-stress capability of freshwater fish

Abstract

The invention discloses a health-care compound feed for enhancing the anti-stress capability of freshwater fishes. The health-care compound feed is prepared from the following raw materials in parts by weight: 0.1-0.3 part of microelement, 0.03-0.06 part of vitamin, 1-2parts of mineral substances, 5-10 parts of fish meal, 10-20 parts of bean pulp, 20-40 parts of miscellaneous meal, 20-40 parts of bran distilled grain dregs, 5-10 parts of flour, 3-5 parts of alfalfa meal, 4-8 parts of kelp powder and 1-2 parts of grease. The health-care compound feed is convenient to use and free of toxic and harmful effect, and contains 28% of crude protein. According to physiological characteristics of the freshwater fish, not only are nutrition indexes required by the fishes achieved through the raw materials such as high-quality fish meal, miscellaneous meal and bran distilled grain dregs, but also the anti-stress capability and the immunity of the freshwater fishes are improved and the growth of the freshwater fish is prompted as various anti-stress substances are added.

Description

Technical field:

[0001] The invention relates to a fish feed, in particular to a compound premixed feed capable of enhancing the anti-stress ability of freshwater fish. Background technique:

[0002] The so-called stress refers to a non-specific response of aquatic animals to adverse environmental factors. These factors include: sudden changes in water temperature, sudden changes in water quality, high stocking density, malnutrition and other external stimuli. At present, freshwater fish are often subjected to stress in a high-density and intensive farming environment, which damages the function of the immune system. Therefore, the susceptibility of freshwater fish to diseases is enhanced, and it may even lead to stress-induced death. Huge losses to farmers. Invention content:

[0003] The object of the present invention is to provide a compound premixed feed capable of enhancing the anti-stress ability of freshwater fish. The feed can improve the anti-stress ability and...
