Extract

Lamb performance at grass falls in July/August on upland farms. Allowing sward height to rise has been recognised as having an amoreilating effect. The objective of this trial was to determine the influence of both sward quantity (sward height) and sward quality (sward type) on ewe and lamb performance from mid April to September. An associated objective was the evaluation of the use of clover to replace nitrogen fertiliser.
