M. van  aGrowth and carcass characteristics of crossbred (Mule) sheep.  aIn: ANNUAL MEETING OF THE BRITISH SOCIETY OF ANIMAL SCIENCE, 2002, York. Proceedings... Medlothian: BSAS, 2002. p. 195.c2002  aThe results show that by using high-index rams the leanness of the carcass of their crossbred offspring can be improved, with no negative effect on live or carcass conformation and with only a small increase in size. The goal to keep the size of crossbred ewes unchanged is considered important to overall efficiency. High-conformation rams gave slightly quicker finishing lambs with larger fat depths, but live and carcass conformation did not improve. This implies selection on index improves carcass quality, whereas the benefit of selection on live conformation remains unclear.  aSheep1 aLEWIS, R.
