ABSTRACT
Abstract | Peste des petits ruminants (PPR) is a highly contagious viral disease in small ruminants causing huge loss to farmers. In this study, an attempt has been made to estimate the economic losses based on the annual incidence, morbidity, mortality levels etc. derived from literature, discussion with experts, and based upon scientific facts. Different mathematical models were used to assess the losses due to mortality in young and adult sheep/goats, body weight loss in young and adult sheep/goats, milk loss, loss due to increased inter-lambing/kidding period, loss due to increased abortion, cost of high feeding and rearing inputs in young and adult sheep/goats etc. The results revealed that at the annual 10% incidence level, the estimated total loss due to PPR in sheep and goats was INR 5041.5 million (77% was mortality loss and 23% was morbidity loss) and INR 11074.6 million (73% mortality loss and 27% morbidity loss), respectively. Further, sensitivity analysis under Ceteris paribus, revealed a loss of INR 8058.8 million and INR 24174.1 million at the minimum (5%) and maximum (15%) incidence levels, respectively. Thus, the estimated loss due to PPR in sheep and goats is dependable till the large-scale primary survey estimates are available in India.
