Cymelarsan and Cymelarsan OTC combination cleared the parasite from peripheral blood; OTC delayed the death as compared to the untreated group. Thyroxine (T4), progesterone levels decreased post-infection significantly. Their levels returned significantly to normal values after treatment with CymelarsanR and Cymelarsan ROTC. OTC did not correct the decrease in infected animals. Keywords: Nubian goats;T. evansi;chemotherapy;thyroxine and progestrone
