Field records (715) of pelvic measurements and growth characteristics were obtained from three herds of Simmental cattle in different areas of the country. Heritabilities for pelvic area, actual pelvic measures (horizontal and vertical measures), ratios of actual pelvic measures, birth weight, adjusted 205-d weaning weight, postweaning average daily gain, adjusted 365-d weight, weight/d of age and relative growth from weaning to 1 yr of age were computed. Genetic, phenotypic and environmental correlations among the various traits were estimated. The heritability of pelvic area was .53 +/- .14, indicating that it is a characteristic that should respond favourably to selection. Positive genetic correlations were found between pelvic area and the various growth characteristics, including birth weight (.73 +/- .25).
