Abstract

The invention discloses a feed additive for improving immunity and aeromonas hydrophila resistance of procypris merus. The fish feed comprises 10-15 parts of a ginkgo leaf extract, 5-15 parts of a green coffee bean extract, 5-10 parts of okra leaves, 2-5 parts of cinnamomum camphora leaves, 2-5 parts of holly leaves and 5-10 parts of a garlic extract, the raw materials are mixed to prepare the Chinese herbal medicine mixed feed additive, and then the Chinese herbal medicine mixed feed additive is prepared into a fish feed. The raw material components in a feed formula are as follows: 0.5-10g of the feed additive, 90-100 g of fish meal, 280-300 g of soybean meal, 250-300 g of rapeseed meal, 210-250 g of bran, 110-150 g of rice bran, 10-20 g of fish oil, 10-20 g of soybean oil, 10-20 g of choline chloride, 20-25 g of a mineral premix and 10-15 g of a vitamin premix. The feed additive and the feed composed of the feed additive can promote the growth of procypris merus bodies, improve theutilization rate of the feed, increase the phagocytic rate of immune cells and the activity of lysozyme, improve the disease resistance of procypris merus, and significantly improve the survival rateof procypris merus infected with aeromonas hydrophila. According to the invention, the physique of procypris merus is effectively improved, and external stress and aeromonas hydrophila infection are effectively resisted.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive and feed for improving the immunity and anti-Aeromonas hydrophila of carps. Background technique [0002] Aquaculture provides a source of protein for the food industry and has grown rapidly in developing countries in recent years. With the improvement of breeding productivity and the promotion of high-density breeding technology, production risks such as epidemic outbreaks and environmental damage are also increasing. Especially high-density cultured fish are more vulnerable to pathogens. Therefore, chemical drugs and antibiotics are widely used to treat infectious diseases in aquaculture. However, the use of drugs will increase water pollution, and its drug residues will also move up the food chain, which will eventually have a negative impact on human health. In this context, finding new means of disease prevention and control has become an urgent nee...
