Peso, histometria tubular e alterações histopatológicas testiculares em rufiões equinos da raça Mangalarga. Arquivo Brasileiro de Medicina Veterinária e Zootecnia, Belo Horizonte, v. 50, n. 3, p. 247-252, 1998.e- 1678-4162http://repositorio.bc.ufg.br/handle/ri/12602Fifteen Mangalarga stallions were divided into three groups. Group l was formed by stallions and groups II and III by stallion teasers. After orquiectomy, weight, tubular histometry and histopathology of the testis were performed. Results indicated no significant differences between stallion and stallions teasers for weight and histometry. lt is concluded that ali animais were capable of detecting estrus and none of the changes observed were attributed to seasonality.porAcesso AbertoTestículoHistometria tubularRufião equinoTestisTubular histometryStallionStallion-teaserArtigo
