RESUMO:

A pelve é considerada um complexo osteoligamentoso, classificada como dolicopélvica em ruminantes. Prejuízos ligados à incompatibilidade canal pélvico/tamanho fetal relacionam-se diretamente à anatomia e disposição pélvica. A característica de área pélvica apresenta herdabilidade variando de moderada a alta, indicando sua importância na seleção animal. A pelvimetria inclui formas direta e indireta. Neste estudo utilizaram-se vinte e seis vacas multíparas, da raça Nelore, agrupadas de acordo com o estágio reprodutivo, cíclico e em início de estágio puerperal (até 30 dias pós-parto). Através deste, objetivou-se evidenciar a relação das medidas pélvicas internas e externas nos diferentes períodos reprodutivos e coletar obter dados referentes a utilização da área interna do hexágono no estudo pelvimétrico dessa espécie em estágio cíclico ou puerperal. Para tanto, realizou-se, a pelvimetria direta e indireta. Os resultados obtidos, pela análise descritiva, foram maiores para animais em início de estágio puerperal. Por meio da correlação de Pearson podem-se observar fortes correlações entre mensurações pélvicas internas e externas, também entre os grupos propostos, e forte correlação entre elipse pélvica e área interna do hexágono. Pelo teste Tukey diferenças significativas tanto em medidas internas e externas puderam ser demonstradas. Conclui-se que as condições anatômicas da pelve variam de acordo com o estágio reprodutivo do animal, que aferição da área pélvica utilizando a formula proposta para área do hexágono interno é relevante pois foi possível comprovar a diferenças estatísticas de áreas nas fases cíclica e puerperal.
