Abstract

The aim of the paper was to quantify the milk performance and conformation traits of the bull dams and candidate bull dams belonging to the Romanian Black and White cows from Timiş County. The study was conducted on 225 candidate bull dams and 55 bull dams, from year 2008-2009. Milk production was corrected for mature equivalent using standard correction coefficients. Candidate bull dams produced 8719.4 kg milk with 3.933% fat and 343.9 kg milk fat. Milk yield ranged from 6762 kg to 12518 kg, and fat yield from 257.5 kg to 522.5 kg. The fat percentage was as low as 3.28% up to 4.65%. Average breeding value for milk was 132.06%. The average production of the bull dams was 9686.9 kg milk and 3.945% fat, meaning a ME milk fat yield of 383.35 kg. The average breeding value of the bull dams was 132.51%. Average body weight of the bull dams was 651.1 kg, and their height was 139.5 cm at withers and 140.4 cm at rump. Average score for conformation was 86.1 points. Average global selection index for bull dams was 105.39 that is very low considered the genetics of the studied cows.
