Castration of bucks is a management practice that has significant implications for breed improvement and market-oriented buck production. This study evaluated the haematological alterations induced by Burdizzo castration, in-situ spermatic cord ligation and orchidectomy in red Sokoto bucks. A total of 16 red Sokoto bucks, six months to one-year-old and weighing between 11 to 12 kg, were randomly assigned into 4 groups (A, B, C and D) of 4 bucks. Bucks in groups A, B and C were castrated by Burdizzo, in-situ spermatic cord ligation and orchidectomy while group D was not castrated. Blood was collected pre-castration, and immediately at 4, 8, 12, 16, 20, 24-, 32-, 48- and 72-hours post-castration (HPC), and processed for haematology. Results revealed non-significant decrease (P>0.05) in packed cell volume, haemoglobin concentration and total red blood cells by 4 HPC and a return to normal values by 12 hours HPC with non-significant fluctuations up to 72 HPC in groups A, B and C. There were significant increases (P<0.05) in the total white blood cells and neutrophil count in all castrated bucks at immediate PC with severe increase observed with orchidectomy. No significant difference (P>0.05) in the lymphocyte count was observed in all bucks for up to 72 HPC. Burdizzo castration and in-situ spermatic cord ligation induced less haematological alterations compared to orchidectomy in the Sokoto red bucks.
