THE CORELATION BETWEEN CONFORMATION TRAITS AND MILK PRODUCTION AT HOLSTEIN COWS

The objective of this research was to evaluate the correlation between the conformation traits and milk production at Holstein cows in Romania. It is well known the fact that milk production is influenced by many factors like: management, genetics, nutrition, season etc. But this study wants to reveal if the milk production is correlated with the conformation traits and how they influence it. In the study were taken farms from three different areas of Romania, East, South and West, also were analyzed farms of different size (small, medium and big). The animals that took part at the study were at first, second or third lactation. For all the cows were appreciated a number of 22 characters, characters that are separated in five different groups: dairy capacity, dairy character, rump, feet & legs and mammary. All the classified animals were between 20-120 days in lactation. To avoid possible inconclusive conclusion, in the study were compared cows from same area, farm dimension and number of lactation.
