effect of castration and docking of lambs on maintenance behaviour and cortisol level
Journal Title: Journal of Veterinary Medical Research - Year 2008, Vol 18, Issue 2
Abstract
Thirty apparently healthy lambs with average weight and age of 5.8±0.5 kg and 15±1.6 days respectively were chosen in Sids Agricultural Research Station belonging to Animal Production Research Institute in Beni-Suef governorate to investigate the effect of castration and docking on maintenance behaviour and blood cortisol level during and after such operations. Lambs were classified into castration (n=10), docking (n=10) and control (n=10) groups. The results revealed that castration and docking could significantly affect the behaviours of standing idle, recumbency, sleep, suckling and ingestion in lambs. Moreover, blood cortisol level was significantly (p<0.05) increased after operation in castrated and docked lambs as compared to the time before, at operation and 3 hours after operation.
