Abstract
The current research aims to study the influence of mastitis on resumption of ovarian activity and postpartum reproductive measurements in Egyptian Baladi cows. Total of twenty-four postpartum cows, were split into two groups of twelve in each. The first group (12 cows) had mastitis, while the second group (12 cows) was healthy. The cows were monitored after calving directly and had their udders screened for subclinical mastitis using the California Mastitis Test (CMT). The present results indicated that the incidence rate of sub-clinical mastitis cases in cows were significantly (P < 0.05) higher (75%) than clinical mastitis cases (25%).The interval from parturition to first ovulation, first service and conception was significantly (P < 0.05) longer (48.3±7.8,96. 5±14.4,and153.2±12.5, days) in mastitic cows than(27.4± 5.6, 72.3± 11.2, and 85.6±15.2, days) in healthy cows. The conception rate following the first service was significantly (P < 0.05) lower (25%) in mastitic than in healthy cows (66.7%). In conclusion, the present results indicate a negative impact of mastitis by delaying the resumption of postpartum ovarian activity and reproductive measurements in Baladi cows. The current study recommends that small breeders must pay attention to the health of the udder, especially during the postpartum period, to reduce the incidence of mastitis and its harmful effects on the reproductive characteristics of lactating cows.
