AN24386The influence of genetic and environmental factors on performance of Brahman heifers grazing pastures in northern Australia

Determining the reasons for among-animal variation in performance of beef cattle on pasture is difficult. In this study, differential diet selection and differences in rumen fermentation were largely ruled out as causal factors. Pen-based studies suggested that differences in voluntary intake under conditions of adequate nutrition may be a factor explaining differences in performance on pasture. A pasture-based method for measuring intake is essential to confirm this hypothesis.
