Non-surgical castration in bucks a comparative study between chemical castration and external ligation of the spermatic cord
This study aimed to evaluate the effectiveness of intra-testicular injection of formalin and external ligation of the spermatic cord in inducing sterilization in bucks. Twelve's adult bucks were used which allocated randomly and equally into three groups. The first group served as a control gro...

| description | This study aimed to evaluate the effectiveness of intra-testicular injection of formalin and external ligation of the spermatic cord in inducing sterilization in bucks. Twelve's adult bucks were used which allocated randomly and equally into three groups. The first group served as a control group injected (5) ml distilled water intra-testicular, while the second group injected (5) ml of 3% formalin and in the third group external ligation of spermatic cord with silk was used.Blood samples were collected from all bucks prior and post to treatment to assay serum testosterone level. In addition, semen samples were collected via artificial vagina to evaluate some semen parameters.Clinical follow-up of animals revealed no any secondary complications in control group, while treatment group showed certain minor complications such as testicular swelling, hydrocele, scrotal ulcer and lameness which disappeared in a short time.Results indicated that testosterone level were significantly decline P |
