Resumen:
To
describe the epidemiology of cystic ovarian disease (COD), to find possible
risk factors associated with the incidence of cysts and to analyse the impact
of COD on the reproductive performance of dairy cows, databases from 22 dairy
herds from the main dairy region in Argentina were retrospectively evaluated
throughout a 3-year period (2009?2011). A total of 248 COD cases over 9156
parturitions were recorded, resulting in a cumulative incidence rate of 2.7%.
Cystic ovarian disease incidence density was lower during the first 100 days
postpartum (DPP) than during later stages of lactation. Seasonality had a
significant influence on the disease presentation with higher incidence rates
during winter and spring. Cows with a previous diagnosis of clinical mastitis
showed 2.72 times more chances of developing ovarian cysts. Cystic cows had longer
calving to first service and calving to conception intervals and lower
conception rate than controls.
