“…Castration can be achieved through surgical means, banding or Burdizzo clamp (Coetzee et al, 2010). The age of castration, hygiene and sterility, and pain management constitute the considerations for castration in goats (Underwood et al, 2015;Chen et al, 2022).…”

I In this study, we assessed the behavioural responses, scrotal circumference, and testicular histo-architecture of red Sokoto bucks after undergoing castration through Burdizzo, in situ spermatic cord ligation, and orchidectomy. Sixteen red Sokoto bucks aged 6 months to 1 year, weighing between 11-12 kg, were randomly assigned to four groups, each comprising four bucks: Group A (Burdizzo), B (in situ spermatic cord ligation), C (orchidectomy), and D (control). Following the castration procedures, the bucks were observed for behavioural changes, and scrotal circumference was measured. Testicular tissue sections were collected from bucks in Groups A and B at 3-, 6-, and 9-weeks post-castration, and processed for histological examination. The findings revealed diverse behavioural responses in Groups A, B, and C, including back arching, vocalization, teeth grinding, altered posture, changes in appetite, and dorsal lip curling. There was a significant (p < 0.05) progressive decrease in mean scrotal circumference in Groups A, B, and C. Histologically, the testes exhibited empty seminiferous tubules with fibrous architecture from three to nine weeks post-castration in Groups A and B. Castration via Burdizzo, in-situ spermatic cord ligation and orchidectomy induced distinct behavioural responses and changes in scrotal circumference in the red Sokoto bucks. The behavioural responses observed in the present study were noted to be mild in Group A, while Groups B and C presented moderate responses, thus, suggesting a varying degree of pain induction. This implies that Burdizzo castration induced less pain when compared to in-situ spermatic cord ligation and orchidectomy. Testicular histo-architecture was altered by Burdizzo and in-situ spermatic cord ligation in red Sokoto bucks. Therefore, the choice of castration method for red Sokoto bucks should be based on the specific characteristics of interest, availability of equipment, convenience, and technical efficiency.

“…Moreover, the castration of rams reduces the smell of mutton, suggesting that castration confers some improvement to the quality of the meat [5]. Castration is an important technical means by which the quality of goat meat can be improved [6]. However, how castration affects goat meat quality has yet to be scientifically determined.…”

Yudong black goats (YDGs) are a local breed in southwest China that possess unique meat qualities and produce a high meat yield, making them ideal models for studying goat meat quality. Castration may decrease off-odors, significantly change metabolites and improve meat quality. Using multi-omics techniques, this study focused on Yudong black goat wethers (YDW, n = 4) and Yudong black bucks (YDB, n = 4). The findings revealed that 33 differentially expressed genes (DEGs) and 279 significantly changed metabolites (SCMs) influenced goat meat quality by affecting fat accumulation and lipolysis regulatory processes. Herein, several candidate genes (IGF1, TNNT2, PPP2R2C, MAPK10 and VNN1, etc.) were identified that play a role in regulating meat quality, non-castrated and castrated, alongside a series of metabolites that may serve as potential meat quality biomarkers. Lipids (triglycerides, oxidized lipids_5-iso PGF2VI, ceramide (t18:1/36:2(2OH)) and Carnitine C20:5, etc.) were significantly higher in the castrated goats. These results revealed that lipids and hydrophilic metabolites were affected by castration, which might be beneficial in terms of goat meat quality. This study aimed to investigate the differences in meat quality between uncastrated and castrated male goats and the possible molecular regulatory mechanisms.
