Contagious caprine pleuropneumonia (CCPP) is a fatal disease of goats occurring in many countries of Africa and Asia where the total goat population is more than 500 million. Vaccination is the most cost effective technique in the control of CCPP than any other control measures. In National Veterinary Institute (NVI) inactivated mycoplasma protein based vaccine obtained by centrifugation has been in use since many... Read more.
