Abstract:
The aims of the work reported here were, first, to summarise the available information on nutritive characteristics of perennial pastures in northern Victoria and to examine factors that affected these characteristics. Second, in order for farmers to use such information, we needed to confirm that estimates of nutritive characteristics and selection differentials (the ratio of the concentration of a nutrient in herbage consumed relative to that in herbage on offer) defined in research with irrigated pastures in northern Victoria could be applied to commercial dairy farm situations. Finally, regression models were used to relate selection differentials for
