Chinese herbal medicament immunopotentiator for high-density breeding of grass carp and preparation method thereof

Abstract

The invention relates to the field of feed additives, in particular to a Chinese herbal medicament immunopotentiator for high-density breeding of grass carp and a preparation method thereof. The Chinese herbal medicament immunopotentiator consists of the following raw materials in parts by weight: 80 to 120 parts of manyprickle acantopanax root, 50 to 100 parts of eucommia bark, 100 to 120 parts of rhubarb, 50 to 100 parts of astragalus mongholicus, 80 to 100 parts of scutellaria laterifolia, 100 to 150 parts of indigowoad leaf, 50 to 80 parts of sophora alopecuroids and 50 to 80 parts of pilose asiabell root. Aiming at the problem of weakened immunity of the grass carp in intensive and large-scale production of a grass carp breeding industry, the Chinese herbal medicament immunopotentiator serves as a feed additive and is applied to a grass carp high-density breeding feed to ensure that the immune function and the survival rate of the grass carp are improved. The Chinese herbal medicament immunopotentiator is safe and reliable for long-term use, does not have toxic or side effect and is low in cost; by the adoption of the Chinese herbal medicament immunopotentiator, the grass carp can grow quickly, the feed conversion ratio is high, and the economic benefits are greatly improved.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a Chinese herbal medicine immune enhancer for high-density cultivation of grass carp and a preparation method thereof. Background technique [0002] Grass carp farming has the advantages of low feed cost and obvious economic benefits; grass carp itself also has the advantages of tender meat, few thorns, and fast growth. It is an excellent main and supplementary species. Under the conditions of intensive aquaculture, increasing the breeding density is an important way to increase the production of aquaculture and reduce the cost of aquaculture. However, excessive breeding density will cause stress, reduce the resistance of fish to diseases, and even affect their growth. Li Aihua (1997) added vitamin C to grass carp feed and Tocher et al. (2002) added vitamin E to turbot feed, and added vitamin C to gilthead sea bream and channel cattail feed. All of them showed that the above nutrie...
