Sterilization of free-ranging female capybaras (): a comparison between two surgical techniques.

This study evaluated two surgical sterilization techniques in free-ranging female capybaras ( = 21). The first group underwent uterine horn ligature (HL; = 11), while the second was subjected to partial salpingectomy (S; = 10). We assessed total operative time, incision length, the ease of identifying reproductive structures, the adequacy of exposure for surgical performance through flank or midline approaches, and the extent of abdominal viscera manipulation for each method.

Surgical sterilization of free-ranging capybaras (): "Passos Nunes" uterine horn ligature.

Capybaras are the primary hosts of tick, vectors of bacteria, and the zoonotic agent of Brazilian Spotted Fever (BSF). In this context, contraceptive methods have been suggested for population control in order to reduce the number of free-ranging capybaras cohabiting with humans in urban and rural areas and acting as disease amplifiers. To maintain the group's expected behavior and social hierarchy, sterilization techniques that preserve the gonads are recommended.
