Previous work (Hyslop et al, 2003) has shown that when finished intensively, 3/4 beef-bred weaned suckled bulls from the UK suckler herd can produce high quality carcasses efficiently with rapid growth rates. Attempting to finish heifers rapidly has traditionally proved difficult since heifers are prone to high carcass fat levels at unacceptable low carcass weights. The objectives of this study were to examine intake, growth and slaughter parameters of weaned suckled heifers from contrasting suckler cow types which had been sired by either a traditional UK beef breed or a continental beef breed and subsequently finished rapidly to slaughter at 14-15 months of age.
