Abstract

The invention discloses a feed additive capable of improving survival rate of hybrid snakehead fingerlings as well as a feed and a preparation method of the feed additive. The additive is prepared from a functional additive A and a functional additive B, wherein the functional additive A is mainly prepared from the following raw materials in parts by weight: 20 to 40 parts of compound Chinese medicinal herb extract, 15 to 30 parts of compound amino acid, 8 to 16 parts of taurine, 10 to 20 parts of beer yeast extract, 5 to 15 parts of betaine and 5 to 10 parts of mannan oligosaccharides; the functional additive B is a micro-ecological preparation and accounts for 10 percent to 20 percent of the total weight of the additive. The additive disclosed by the invention has a feeding attraction effect and is used for accelerating conversion of feeding habits of the hybrid snakehead fingerlings, promoting digestive tract development of the fingerlings and improving the digestion and absorption rate of nutrient substances of the feed so as to promote the growth of the fingerlings; furthermore, the additive can also be used for improving the organism immunity of the fingerlings and reducing the bursting of diseases. When the additive is added into the feed, the survival rate and the weight gain rate of the fingerlings at a feeding habit conversion phase can be improved; a preparation process is simple and the cost is low.

Description

technical field [0001] The invention relates to a feed processing technology in aquaculture, in particular to a functional feed additive for improving the survival rate of hybrid snakehead seedlings and a preparation method thereof, as well as a functional feed containing the additive and a preparation method thereof. Background technique [0002] Hybrid snakeheads (obtained by crossing the black snakehead as the male parent and the spotted snakehead as the female parent) have hybrid advantages such as delicious meat, strong resistance, larger individuals, faster growth, can eat artificial compound feed, and can withstand long-distance transportation and low temperature. , has now replaced snakeheads and snakeheads as the main species of snakehead fishes, and has been vigorously promoted in the Pearl River Delta, Jiangsu, Zhejiang and the two lakes. [0003] The yolk sac provides nutrition for hybrid snakeheads when they first hatch, and they start to eat actively after 3 da...
