Physiological Responses of Adult Nubian Goats (Capra hircus) to Orchiectomy

Aim: This study was designed to investigate the effects of bilateral surgical castration on physiological responses in adult Nubian goats.

Methodology: Twenty male goats (bucks) were assigned to two equal groups, group A served as control and group B was subjected to bilateral castration; both groups were monitored for 4 weeks. The effects of castration on thermoregulation, hematological variables, and serum biochemical constituents were investigated. An independent T-test was used to assess the effects of orchidectomy on the parameters monitored.

Results: Castration increased Tr, RR, HR, TLC and decreased bodyweight, PCV, RBCs, and Hb concentration. The ratios of lymphocytes, monocytes, and eosinophils decreased associated with an increase in the ratio of neutrophils. The castrated group had lower serum total protein and albumin concentrations and had higher urea, plasma glucose, GOT and GPT concentrations compared to the intact group.

Conclusions: The study concluded that castration altered thermoregulation, hematological and biochemical parameters in adult Nubian goats.
