The aim of the study was to observe the ovarian activity in crossbred cows affected with Foot and Mouth disease. The study was conducted with two groups of animal. Group I consisted of twenty (20) crossbred cattle from Instructional Bovine Farm, Ranchi Veterinary College, India and group II consisted of forty (40) crossbred (Jersey and Holstein Friesian) cattle having clinical signs of Foot and Mouth Disease(FMD) from in around Ranchi, India. The animals were clinically examined for the presence of characteristic symptoms of FMD and were confirmed on the basis of enzyme linked immunosorbent assay (ELISA). Blood samples were collected, taking all aseptic precautions, from the animal by jugular vein puncture between 10 am to 12 noon. The serum progesterone levels during follicular and luteal phase were determined by method of ELISA using the standard curve and then analyzed by analysis of variance (ANOVA). In the present study, the serum progesterone level in control animals was 0.770 ± 0.110 ng/ml which decreased non-significantly to 0.660± 0.220 ng/ml in the FMD affected animals during the follicular phase of the oestrus cycle. Again, it was observed that during the luteal phase the concentration was 7.310 ± 1.546 ng/dl which also decreased non-significantly to 5.037± 1.066 ng/ml in the FMD affected animals. Serum progesterone level of serum samples from positively tested samples of crossbred cows were analyzed by ELISA during follicular phase and luteal phase of oestrous cycle. Thus, from the study it can be concluded that during FMD, the ovarian activity is affected.
