Description
It was shown that large varietal differences in voluntary intake occur even· when there were no differences in dry matter digestibility and level of pepsin soluble dry matter. To overcome this problem when comparing different methods of predicting intake the use of multiple regressions was proposed in which dry matter digestibility was always one of the two independent variables. Using this method leaf % was shown to be the best predictor of intake (r = 0.87) closely followed by physical attributes of the feed. It was concluded that more time should be spent studying the physical factors in pastures that control intake and that less reliance should be placed on chemical analysis.
