Thirty local breed cattle (2-5) years old naturally infected with Anaplasma marginale were used in this study, the animals were divided randomly into three equal groups (10 animals for each), first group was treated with Imidocarb dipropionate, intramuscular at a dose rate of (3.5) mg/kg B.W. Second group treated with oxytetracycline 20%, intramuscular at a dose rate (20) mg/kg B.W. Third group treated with diminazine aceturate, intramuscular at a dose rate of (3.5) mg/kg B.W. All medications repeated after (48) hours. Clinical signs, hematological changes, percentage of parasitemia and some changes of biochemical values pre and post treatment used for evaluation of therapeutic efficacy against natural infection with bovine anaplasmosis.
Results indicated that Imidocarb dipropionate at a dose rate of (3.5) mg/kg B.W., intramuscular, repeated after (48) hours is more effective in the treatment of bovine anaplasmosis in comparasion with Oxytetracycline 20% and Diminazine aceturate.
