| Due to economic, environmental and animal-welfare constraints, it is envisaged that in the future a larger proportion of the milk produced in temperate regions will be produced from grazed pasture. However, with the selection of modern higher-production dairy cows, increased emphasis on product quality and issues associated with nitrogen leaching, soil compaction, greenhouse-gas emissions and animal welfare, pasture-based systems will also require higher per-animal productivity in the future. This will necessitate the development of grazing systems designed to maximize daily herbage intake per cow, while at the same time maintain a high-quality pasture over the entire grazing season. Daily grass DM intake will be maximized by adhering to important sward... |
