dc.description.abstractHereford cows were mated to semen (total 2438 doses) from seven sire breeds (Angus, Belgian Blue, Hereford, Jersey, Limousin, South Devon and Wagyu). A total of 97 sires were represented over four matings from 1993-1996 with an overall calving rate of 62%. Only 19% received a repeat dose of semen. Year of mating and cow age significantly affected calving rates and gestation lengths. Sire breed differences were not significant. However, a wide range of success rates were noted for individual sires.
