Résumé
Hermaphroditism is a term used to describe animals that have genitals of both genders. This anomaly has been described in reptiles such as lizards and snakes. The jabuti species Geochelone carbonaria hull has a high and very concave bone which is covered by corneal plates with yellow spots at the center, and collect the neck caudally into the hull. Although sexual dimorphism is externally quite clear, the females have straight plastron, while the male presents a clear concave plastron that serves to facilitate the mounting and a well developed penis having the size of the animal body. However, hermaphroditism in this species can only be confirmed with additional exams.

Mastitis is an important problem for the Santa Inês ewes and is a disease strongly related to the management carried out in the herd. A comparative study was carried out between the proposed method based on drying (treatment) and the traditional method (control). Sixty-two Santa Inês ewes raised in a semi-extensive system were divided in two groups of 31 ewes each: treatment group (G1) and control group (G2). The animals were monitored each week searching for clinical sings of mastitis. In 8.4 percent of G1 and 41.3 percent of G2 animals, the udder was warm and hyperemic. The presence of residual milk was lower in G1 (24.3 percent) compared to those of G2 (74.2 percent). The proposed treatment for the control of ovine mastitis significantly reduced the frequency of the clinical signs of the disease.
