Abstract

The invention discloses a compound Chinese herbal medicine immunopotentiator of Penaeus vannamei Boone. The compound Chinese herbal medicine immunopotentiator comprises 5-30% of bark of eucommia, 5-40% of radix astragali, 5-30% of honeysuckle flower, 5-30% of radix bupleuri, 5-30% of giant knot weed, 5-30% of phellodendron, 5-30% of licorice root, 5-30% of epimedium, 2-20% of Chinese magnoliavine fruit and 2-20% of pilose asiabell root. The compound Chinese herbal medicine immunopotentiator of Penaeus vannamei Boone replaces an antibiotic, promotes Penaeus vannamei Boone growth, improves immunity and reduces diseases. Through use of 0.5-3.0% of the compound Chinese herbal medicine immunopotentiator in forage, a Penaeus vannamei Boone growth speed is improved by 5-15%, a forage coefficient is reduced by 0.05-0.2, immunity and low-oxygen tolerance of Penaeus vannamei Boone are improved, and Penaeus vannamei Boone mortality caused by vibrio alginnolyficus is reduced.

Description

Technical field [0001] The invention relates to an aquatic feed additive, in particular to a shrimp immune enhancer, which is suitable for breeding Litopenaeus vannamei.
