Description of the research topic:
The profitability of cattle breeding is greatly influenced by the rate of calves being born alive and reared to adulthood. However, despite the speedy developments of animal breeding, perinatal mortality is still very high (4 to 7%) and constitutes approximately half of the total calf losses. During the last decades, there has been a trend of increasing rates of stillbirths, especially in Holstein Friesian (HF) heifers (10 to 13.2%). which nowadays shows a static or declining trend. These losses highlight the importance of examining the causal factors of perinatal mortality
