The objective of this study was to estimate the breeding values and genetic parameters for birth weight and weaning weight in Aberdeen Angus cattle breed with maternal animal model. Data consisted of records of 1206 calves of Aberdeen Angus breed from Aberdeen Angus Association Romania. The direct breeding values for birth weight were in the population between -12.8 and 21.93 and for weaning weight from -82.68 to 155.10. The direct breeding values for calves with records for birth weight were from -8.87 to 16.077 and for weaning weight from -71.51 to 150.26. The maternal breeding value for birth weight ranged between -2.772 and 3.388 and for weaning weight from -38.273 and 49.693 in the population. The maternal breeding values for calves with records for birth weight ranged between -2.206 and 1.668 and for weaning weight were from -25.824 and 27.906. The direct heritability for birth weight was 0.266 and for weaning weight was 0.217. The maternal heritability was 0.048 for birth weight and 0.081 for weaning weight. The total heritability was 0.24 for birth weight and 0.20 for weaning weight.
