Prothrombin time and activated partial thromboplastin time in goats raised extensively at Rio Grande do Norte State, Brazil

Abstract

This study aimed to establish normal pattern for the prothrombin time (PT) and activated partial thromboplastin time (APTT) in goats extensively raised at Rio Grande do Norte state, Brazil. A total of 40 clinically healthy adult goats (13 males and 27 females) aged 1 to 6 years-old was used. Blood samples were collected from jugular vein in tubes containing 3.8% of sodium citrate. The plasma was immediately separated by centrifugation and refrigerated at ± 4ºC and after submitted to PT e APTT determinations through manual methods using commercial kits. The results for goats in the region of 25.4 ± 0.90 and 39.5 ± 1.41 seconds, respectively, for PT and APTT were in an adequate range.
