Abstract

This case report aimed to treat a bilateral hygroma in a 2-month-old Dorper lamb ram in a flock of sheep at Rafin Guza, Kaduna North Local Government Area, Nigeria. The flock comprised twenty Dorper sheep (18 ewes and 2 rams) with a history of swollen joints in one lamb ram, there was a history of medication with dewormer (Albendazole), Injection Tylosine, and Injection of 20 % Oxytetracycline in the flock. Physical examination on the farm visit showed an apparently healthy flock except for the lamb with carpal hygroma. The lamb ram weighed 20 kg with a slightly pale mucous membrane, unilateral enlarged pre-scapular lymph nodes, and bilateral carpal hygroma. Vital parameters like temperature, pulse, and respiratory rate were 38.2oC, 60 beats/min, and 17 cycles/min, respectively, which was within the normal range. Bacteriological and serological tests were carried out using the blood and hygroma fluid samples collected aseptically from the lamb ram. The result showed the lamb had leucocytosis and neutrophilia on hematology, the serum sample was positive for Rose Bengal Plate Test (RBPT) and the culture showed positive for Brucella spp. Hence, there is a need for proper surveillance in the study area because of the public health and economic threat that can be posed by Brucella spp found on the farm.
