Information is needed on the amount and nutrient concentrations of manure generated by lactating dairy cows that are managed in an intensive grazing system. Currently the most frequently cited data sources for these are 20-year old ASAE tables. These data are important because manure nutrient figures are used to determine the maximum animal stocking density that will safeguard against nutrient runoff or degradation of water quality by concentrated nutrients.
