Compound bait used for fish culture

Abstract

The invention discloses compound bait used for fish culture. The compound bait used for fish culture is characterized by being prepared from basic daily rations subjected to solid state fermentation and bacillus subtilis, wherein a ratio of the bacillus subtilis to basic daily rations which are not subjected to solid state fermentation is 106-107 CFU/g, the basic daily rations which are not subjected to solid state fermentation contain 53%-58% by weight percentage of plant oil meal and 4%-6% by weight percentage of dried bean dregs, the plant oil meal is prepared from soy bean meal, peanut meal and cottonseed meal with a weight ratio of 1 to (0.2 to 0.3) to (0.5 to 0.7), a preparation method of the basic daily rations subjected to solid state fermentation comprises the steps that 1, rhizopus and mucor racemosus are made into bacterium suspension after being cultured separately; 2, after the plant oil meal is crushed, the mucor racemosus suspension with a ratio of 106-107 CFU/g, the rhizopus suspension with a ratio of 106-107 CFU/g, the plant oil meal and the dried bean dregs are fully mixed, after the water content is adjusted to be 35%-45%, a mixture is placed at 28-30 DEG C for solid state fermentation for 24-36 h, and after the rest components of the basic daily rations, the plant oil meal subjected to solid state fermentation and the dried bean dregs are mixed, a mixture isplaced at 24-26 DEG C for solid state fermentation for 36-48 h again.

Description

technical field [0001] The invention belongs to aquatic medicine, and in particular relates to a compound bait for carps of the family Cyprinidae. Background technique [0002] In the cultivation of economical fish, how to improve the bait so as to improve the growth performance of the fish body has become the key point in the development of the existing new bait. Improve the immunity of the body to adapt to the high-density breeding environment and the existing uneven breeding conditions in my country, and at the same time reduce the use of drugs such as antibiotics. Adding probiotics to feed or biofermenting some feed components are existing means to improve bait. For example, Bacillus subtilis has been approved as a feed additive. In addition, the main substance used as protein in the existing bait is soybean meal. However, my country relies heavily on imports of soybean meal, and its price fluctuates greatly. my country's self-produced vegetable oil meal such as peanut...
