“…The 25 kg difference between AA and BB at the end of the first winter is about what would be expected at that stage given the difference in sire EPD CWT . Numerous studies conducted over the past 20 years in Ireland (Keane and More O'Ferrall, 1988;McGee et al, 2005), Great Britain (Cook and Newton, 1979;Rowlinson et al, 1984) and continental Europe (Oldenbroek, 1980(Oldenbroek, , 1982Reklewski et al, 1985) have compared Friesian and Holstein cattle for beef production traits. All these studies, in agreement with the present findings, noted that overall growth rates were similar for Friesians and Holsteins.…”
