Through retal palpation the pregnant uterine horn was determined. Thus 1009 single pregnancies of Holstein and red Holstein cows, pure breed and cross-breed, were analysed.Through X2 (chi-square) analysis, fixing the rejection level of nullity hypothesis at 5% (P < 0.05), differences between pregnant uterine horns were statistically significant. Values were greater in the right uterine than in the left uterine hom in pure breed and cross-breed Holstein cows, being this distribution note similar in the pure breed cross-beed red Holstein cows. Both in Holstein and red Holstein cows the correlations between the sex of the calves and the pregnant uterine horns were not statistically significant.Downloads
