After the treatment, no fatality cases related to parasitosis were recorded. The mortality was controlled by segregation of all remaining blackbucks and the treatment for internal and external parasites (biting flies and ticks). The blackbucks’ population displayed a general mortality rate of 11.67%, where 25% of total male and 9.62% of total female died.
Deaths were associated with hepatic necrosis, bilateral congestive distention of heart and fibrinonecrotic bronchopneumonia. Seven individuals died due to hemorrhagic parasitic, abomasitis and enteritis caused by Haemonchus spp., Setaria spp., and Trichostrongylids. In February 2012, a reproductive group of 60 adult blackbucks ( Antilope cervicapra) from Veracruz, Mexico was relocated to hunting units in eastern and northeastern Mexico. *Correspondence: April 2014 Acepted: February 2015.
