Abstract
This paper reports a field experiment and a farm survey, which aimed to find out if there is evidence that elevated herbage crude protein (CP):sugar levels have negative effects on dairy cow performance. Differences in herbage CP levels were induced by using nitrogen (+N) or withholding (-N) applied as fertiliser urea for two groups of 20 dairy cows in early lactation (August to November 2003). Cows fed urea-fertilised herbage had elevated milk urea levels (-N = 5.4 mmol/l, +N = 8.3 mmol/l, P
