Application of Chongbiqing in the treatment of dermatomiasis in dairy cattle

Cow skin fly maggots are the larvae of cattle skin flies and striped skin flies, a parasitic disease that lives under the skin of the back of cattle. It can make sick cattle lose weight, stunted growth and decrease milk yield, which has become a major obstacle to the development of dairy industry at present. Since 2004, 34 dairy cows with dermatomiasis have been treated with Chongbiqing, all of which have achieved 100% satisfactory results.
