Abstract
Abstract The effects of lambing policy (June‐ or August‐lambing) and ewe breed cross on midside patch wool growth and wool quality traits were studied for 12 months. Three ewe crosses—Border Leicester × Romney (BR), Poll Dorset × BR (PBR), and Suffolk × BR (SBR)—were used. Twenty ewes of each cross within each lambing policy and balanced for litter size had midside patches clipped at approximately 6‐weekly intervals for 1 year from April. Annual ewe fleece production was measured at the October shearings preceding and following the trial. June‐lambing ewes produced 0.6 and 0.4 kg more greasy and clean wool respectively than August‐lambing ewes (P < 0.001). This extra wool production was not paralleled by a greater total wool growth from midside patches in June‐lambing ewes throughout the 392‐day measurement period. There was, however, a difference in the pattern of wool growth between the two groups. The seasonal decline in wool production that normally occurs over the winter months in August‐lambing ewes...
