Extract

Sward surface height (SSH) has been shown to have an effect on the performance of dairy cows. However, to understand precisely how cows adapt to such differing sward conditions, it is necessary to study the interactions between bite mass, biting rate, and thus intake rate, and time spent grazing. An experiment was therefore designed to examine grazing behaviour and intake by lactating cows at three sward heights.
