Estimation of economic losses due to classical swine fever in pigs in Mizoram

Abstract

Classical swine fever (CSF) also known as 'hog choleraâ' is an important viral disease of pigs in India with serious economic concern due to morbidity and mortality, and affects a vast section of the pig population in India. In present study, a structured sampling design was adopted, which covered the major regions of the Mizoram, to ascertain the economic losses due to CSF in pigs. Available estimates of the economic losses of Mizoram due to CSF are based on single values of various epidemiological and economic parameters. Overall annual morbidity, mortality and case fatality rates of CSF in Mizoram were 8.35, 5.07 and 60.70% respectively. The expected annual economic loss due to CSF in pigs in Mizoram was ` 16,69,34,465. Losses due to mortalities contributed the most to the total economic loss caused by CSF in pigs, followed by loss in body weight. This study revealed significant losses due to the incidence of CSF in pigs of Mizoram.
