Abstract	Reduction of the age of heifers at first calving may lead to improvement of beef cow productivity. Because of the severe calving diffi culties in large-sized heavy muscled beef heifers, a first early calving about the age of 2 years is almost impossible in purebreds (Menissier and Foulley, 1979 1 Menissier et al.,1981). Crossing with sire breeds of smaller size giving lighter calves at birth may be one of the ways to solve these birth difficulties connected with the large size of the foetus relative to the pelvic opening. Using breeding heifers available during an experiment with beef breeds (Colleau et al.,1973 1 FREBLING et al.,1982), we compared for their early fertilization~ T small sized sire bree3s of different biological types corresponding to decreasing risks of birth difficulties : a continental beef breed (Limousin), a British beef breed (Aberdeen-Angus) and a dairy breed (Jersey).
