N2 - The paper reports two plasma metabolites that can be measured to predict clover grass intake from animals on pasture, as the daily contribution of metabolisable energy from fresh grass clover was found to be highly positively correlated with plasma pipecolic acid and a metabolite tentatively identified as plasma bisnorbiotin.

Nitrogen intake increased linearly with increasing fresh grass clover intake, but nitrogen deposition and nitrogen utilization were not affected by grass intake within the range investigated. There was a linear increase in plasma urea content, when grass intake increased from 0 to 6 kg per day.
