摘要

The aim of the study was to determine the reproductive problems caused by the most common diseases that occur during the first 100 days in milking (DM) among Holstein cows managed in the Mexican highlands. In this study, 654 pregnant and near parturition (25±7 days before calving) cows were selected. Following calving, their health status was assessed for a period of 100 days and their reproductive performance (days up to first service, days-open, services per conception, percentage of abortions and pregnancy rate) was recorded up to 171 DM (average days-open of the farm). The cows were grouped as healthy or according to the diseases they suffered from namely mastitis (n = 129), pneumonia (n = 124), digestive problems (n = 117) and lameness (n = 129). The pregnancy rate was affected (P 0.10) to days open, number of services per conception or percentage of abortions compared with the group of healthy cows. Diseases that affected cows during the first 100 DM had a significant effect (P<0.05) to days up to first service compared with the group of healthy cows (Healthy: 77.6±2.9), (mastitis: 70.5±3.2), (pneumonia: 60.6±3.3), (lameness: 81.6±3.2), (digestive problems: 72.4±3.4). In conclusion, Holstein cows that remained healthy during the first 100 days in milk had higher pregnancy rates suggesting that the health of the cows is key to obtain good reproductive profiles.
