| description | The objective of this study was to review and discuss the results of the first international evaluation for female fertility of Holstein dairy cattle. Fifteen countries, including Italy, provided breeding values of bulls and joined the evaluation. Four trait groups were used to analyze animal’s ability to became pregnant and animal’s ability to recycle after calving. Italy submitted three traits: days to first service (DTFS), non-return rate at 56 days (NR56) and calving interval (CI). Genetic correlation between Italy and the other countries ranged from 0.72 to 0.94 for DTFS, from 0.25 to 0.90 for NR56 and from 0.67 to 0.87 for CI. Results represent another step forward in the international trade of dairy cattle genetic material. |
