Abstract
Previous work carried out at Aberdeen to investigate the effect of varying the length of the suckling period post calving on heifer and calf performance has shown little difference in the carcasses of heifers slaughtered twelve weeks post calving compared to heifers slaughtered six weeks post calving (Lowman and Broadbent, 1988). These results further emphasise the nutritional demand for lactation and suggest that major improvements in carcass weight of calved heifers can only be obtained if they are weaned early or allowed an appropriate finishing period after weaning. An experiment was therefore set up to examine the effect of a short finishing period for weaned once-bred heifers prior to slaughter on carcass weight, composition and eating quality and to relate these findings to a group of non-pregnant heifers.
