Abstract
   In this paper we present the results of research on a herd of 120 Aberdeen Angus cattle in which the management and indicators of meat production were followed. The objectives of the research were: the origin of adult cattle, birth weight, weight during fattening, average daily gain in descendants, comparative analysis of meat production indicators by sex. The studied staff had a valuable ascendants. The descendants, for the weight at weighing, had the average value of 239.01 Kg, with the limits between 154 - 340 Kg, and the average daily gain was on average 790 g with the limits between 600 and 1400 g. The explanation lies in the fact that the herd was imported from different countries, areas and farms, but also in the fact that the exploitation system is extensive, on pasture, and in winter it is maintained in semi-open shelters and fed with natural hay, semi-hay or corn silage, wheat bran and sunflower meal. Birth weight is positively and intermediate to strong correlated with weighing weight r = 0.459 (45%) being very significant for p <0.01. Calves that have a high body weight at birth and are vigorous will record good average daily gains, and at the end of the fattening period, very good body weights.
