Genetic and phenotypic parameters for body condition score (BCS), days to first service (DFS), non-return rate (NRR), somatic cell score (SCS), and 305-day milk, fat and protein yields were estimated, using 38930 multiple lactation records of cows across 1830 herds. The cows were daughters of 243 different sires. Singleand multi-trait repeatability animal models were used to estimate parameters...

The objective of this study was to determine the relationship between body condition score changes and the dynamics of energy balance indicators fatty acid and citric acid contents in milk during a early part of lactation. In addition, the relationship between these two indicators was also evaluated. A total of 27 Holstein cows that calved within three consecutive weeks were included in the ana...
