Caracterização de aspectos produtivos de vacas brangus ibagé com distintos graus de fertilidade

Abstract: O presente estudo teve por objetivo caracterizar distintos grupos de fertilidade e averiguar diferenças quanto ao ganho de peso no pós-parto e habilidade materna em uma população Brangus Ibagé (3/8 Nelore + 5/8 Angus). Foram computados dados de 1145 partos de 287 vacas, sendo considerados apenas os registros de 168 fêmeas com, no mínimo, quatro partos. As fêmeas foram agrupadas de acordo com a média do intervalo de partos em grupos de alta, intermediária, e baixa fertilidade. Adicionalmente, foram levantados d… Show more

“…All animals have been exclusively managed on native pasture in an extensive livestock system (Oliveira et al, 1998), with the mating season extending from November 15th to February 15th. Lifetime calving interval data (CI) were obtained for the females of the experimental herd as described by Oliveira et al (2002). As an indicator of cow fertility, the weight at first calving (WFC) was computed as a predictor for growth potential of the heifers.…”
