Abstract

The present invention provides a viral disease preventing and curing feed additive for cyprinus carpio. The feed additive comprises the following traditional Chinese medicinal components in parts by weight: 10-20 parts of radix acanthopanacis semticosi, 5-10 parts of radix codonopsis, 5-10 parts of cortex eucommiae, 5-10 parts of poria cocos, 5-10 parts of radix isatidis, 5-15 parts of mango leaves, and 10-20 parts of a herba andrographitis extract. The provided viral disease preventing and curing feed additive for the cyprinus carpio can enhance immunity of the fish, effectively prevent and cure viral diseases, especially herpes virus for the cyprinus carpio, and promote the growth.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a feed additive for preventing and treating koi viral diseases. Background technique [0002] Koi is physically fit, colorful, with varied patterns and majestic swimming. It is a fish with high ornamental value and economic value. At present, my country has become the main producer and exporter of Koi in the world. Along with its breeding scale constantly expands, the degree of intensification improves constantly, and its disease occurrence also has the tendency of increasing, and the various viral infectious diseases of koi especially koi herpes virus disease begin to spread widely. Koi herpes virus disease first broke out in Israel in 1998, but it was confirmed in 1999 that its true pathogen was Koi herpes virus (Koiherpesvirus, KHV). Since then, outbreaks have also occurred in the United Kingdom, continental Europe, the United States, and Japan. In recent yea...
