Economic Analysis for Selection of Diagnostic Methods against Surra in Buffalo on East Sumba Island, Indonesia

摘要

Surra is one of the main disease problems in buffalo farms in East Sumba Island. The control program of this disease requires the support of diagnostic methods that are reliable and cost-effective. This study aimed to select the diagnostic method for surra based on the economic value of each diagnostic method, including parasitology tests (WBF), Micro-Hematocrit Centrifugation Technique (MHCT), Card Agglutination Trypanosome Test/T. evansi (CATT), and Polymerase Chain Reaction (PCR). Data was collected from various sources including from survey of 30 buffalo farmers on East Sumba Island, Surra cases from the East Sumba Livestock Service Office, diagnostic test data from the Veterinary Research Institute, Indonesian Ministry of Agriculture and various supporting literatures. The economic value of each diagnostic test was analyzed by the decision tree analysis model using WinQSB software. The results showed that the PCR method has the highest economic value of IDR781.3 million, and then followed sequentially by MHCT IDR.668.4 million, CATT/T. evansi IDR 505.5 million and WBF IDR 114.5 million. Based on this study it is recommended to use PCR as a diagnostic test method in controlling Surra disease in buffaloes on East Sumba by considering its economic value.
