Popis: An experiment was conducted to obtain progeny test comparisons of Finnish and Canadian Ayrshire bulls for veal and beef production. A total of 83 male calves from four Canadian and four Finnish sires was tested. Best linear unbiased estimates of differences between veal calf progeny of Finnish and Canadian bulls for time on test, average daily gain and feed conversion were 4.00 ± 5.63 days, −.044 ±.038 kg/day and.062 ±.067 kg dry matter intake/kg gain, respectively. For veal carcass traits, progeny differences between Finnish and Canadian bulls for dressing percent and carcass grade, quality, finish and color scores (scores ranged from 1 to 3, except for color score which ranged from 1 to 2, with high score desirable) were.25 ± 1.13%, −.085 ±.232,.146 ±.303,.122 ±.302 and.104 ±.192, respectively. When raised for beef, differences between Finnish and Canadian sired steers were.015 ±.019 kg/day for feedlot average daily gain and.21 ±.66% for dressing percent. None of these differences were significant (P >.05). Based on these results, the importation of Finnish semen would not be expected to materially change the veal and beef performance of Ayrshires in Canada.
