The nutrient demand of dairy cattle varies with milk yield level and is greater in early than in later lactation. This is likely to influence forage feeding behaviour and intake, although the mechanisms are not well understood. The objectives of this experiment were to examine the feeding behaviour of dairy cows in early and late lactation (representing two levels of nutrient demand), and at three levels of concentrate supplement (representing three dietary influences on demand for forage).
