The physicochemical properties of cervical mucus discharge (CMD), serum oestrogen and progesterone profiles during oestrus (day 0) and metoestrus (day 2) period in crossbred cows with (Group I, n=12) and without (Group II, n=12) history of profuse metoestrual bleeding were studied. Majority of group I cows exhibited clear and transparent CMD (83.33 per cent) with thin consistency (100 per cent), typical fern pattern (83.33 per cent), pH (7.58±0.12) and spinnbarkeit value of 12.64±0.50 cm during oestrus. However, during metoestrus all the cows (100 per cent) exhibited bloody CMD with thin consistency (66.67 per cent), ‘nil’ fern pattern (0.0 per cent), mean pH of 7.96±0.10 and mean spinnbarkeit value of 9.35±0.5 cm. In group I cows, the mean pH and spinnbarkeit values of CMD (7.96±0.10 and 9.35±0.5 cm, respectively) was significantly (p<0.01) higher than that of group II cows (7.64±0.07 and 7.75±0.30 cm, respectively) during metoestrus. The mean serum progesterone concentration of group I cows (1.61±0.55 ng/mL) was significantly (p<0.05) higher than that of group II cows (0.36±0.07 ng/mL) on day of oestrus. The mean serum oestradiol concentration of group I cow (6.85±0.53 pg/mL) was significantly (p<0.05) lower when compared to group II cows (8.48±0.49 pg/mL) during metoestrus. In conclusion, the physicochemical properties of CMD, serum progesterone and oestrogen profiles significantly altered in group I cows during oestrus and metoestrus which showed lower conception rate than that of group II cows.
