VVND is an emerging contagious disease of poultry. There are only limited options to control VVND. Recently clinical and experimental research studies conducted by Chinese veterinary scientists exhibited encouraging action of St. John's Wort and other natural herbs for prevention and control of VVND.
Defense Up is a herbal feed supplement based on St. John's Wort and other natural herbs. St. John's Wort exhibits potent antiviral activity including those causing VVND. Field clinical trials have shown that St. John's Wort successfully prevents poultry birds from VVND. Besides antiviral actions, St. John's Wort has broad spectrum anti-microbial activity which helps in the prevention of secondary bacterial infections, normally encountered during viral diseases. Other herbal constituents of Defense Up help to increase immune-competence of the birds and thus limit the chance of infections. Defense Up helps to relieve symptoms of respiratory tract infection. Therefore, optimizing immune-competence of the birds and strengthening of respiratory functions along with prevention of viral replication by using Defense Up is the most appropriate solution to enable the birds to successfully meet the challenges of VVND for prevention as well as for faster recovery.
