Evaluation of the subcapsular technique for primary closure castration in donkeys (Equus asinus).

Abstract: This study described the subcapsular technique for primary closure castration in donkeys with special regard to its efficiency and welfare impacts. The study was conducted on twelve adult male donkeys, allocated randomly into two groups; subcapsular castration (SC) and open castration (OC) groups, whether the donkeys were subjected to surgical castration either by subcapsular or open castration techniques, respectively. Testosterone, cortisol, lactate, glucose, total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG), and nitric oxide (NO) were measured before and after castration. Pain-associated behavioral activities were recorded post-castration. The SC was successfully performed in donkeys through a single paramedian scrotal incision. The SC was efficient as OC in reducing testosterone levels. The pain score decreased in the SC compared to the OC over time. The SC was an efficient and reliable technique for primary closure castration in donkeys with minimal postoperative complications and care and good cosmetic, physiological, and behavioral outcomes. It can be an alternative to other castration techniques in equines.

The study explored the effectiveness and welfare impact of the subcapsular castration technique in donkeys, comparing it to the open castration method, and found that the subcapsular procedure showed positive results with fewer postoperative complications.

Research Design and Methods

  • The study involved twelve adult male donkeys. These were randomly divided into two study groups.
  • One group was subjected to subcapsular castration (SC), and the other to open castration (OC).
  • The SC was performed through a single paramedian scrotal incision.
  • Various parameters such as testosterone, cortisol, lactate, glucose, total cholesterol, high density lipoprotein cholesterol, triglyceride, and nitric oxide were measured before and after castration.
  • In addition, pain-associated behaviors were observed and recorded post-castration.

Findings

  • The SC method proved to be successful for the primary closure castration in donkeys.
  • It was as effective as OC in reducing testosterone levels.
  • Pain associated with the procedure decreased over time with the SC compared to the OC.
  • Postoperative complications and the need for care were minimal with the SC method, with good cosmetic, physiological and behavioral outcomes observed.

Conclusion

  • The results suggest SC as an efficient and reliable technique for primary closure castration in donkeys.
  • This technique could serve as an effective alternative to other castration methods in equines, improving animal welfare by reducing pain and the risk of postoperative complications.
