Technical Abstract:
There are limited opportunities for reducing total nitrogen excretion by dairy cows, with maximum reductions being in the area of 10-15 percent. There is some opportunity for shifting nitrogen excretion from the urine to the feces, and this would reduce the amount of nitrogen vulnerable to loss in the form of volatile ammonia. Phosphorus excretion can typically be reduced by 25-30 percent, since phosphorus is usually overfed to dairy cows. Reducing phosphorus excretion by this amount will reduce the land required for safe disposal of manure by a like amount.
