Abstract |
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 <0.01) by
diseases, regardless of the type. Healthy cows had the highest (P <0.05)
pregnancy rate (74.19±1.5) compared with diseased cows: mastitis
(46.5±2.1), pneumonia (30.6±1.9), digestive problems (46.1±2.2),
lameness (60.4±2.1). Diseases that affected cows during the first 100 DM
had no effect (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.
