    ABSTRACT : The exfoliative vaginal cytology, vaginoscopic examination of vaginal mucosa and endocrine profiles during different phases of estrus cycle in induced as well as in normal estrus cycle were recorded in the present study. Higher percentage of superficial cells (89.94 ± 0.64) and lower percentage of intermediate (7.30 ± 0.77) and parabasal cells (2.76 ± 0.30) were characteristic vaginal cytological changes in bitches during estrus. Vaginoscopic examination revealed that the vaginal mucus was creamy and paper white with angular shrinkage during estrus. The estrus was induced with Cabergoline (CABG) and Pregnant Mare Serum Gonadotropin (PMSG) in two groups of bitches. The progesterone, estrogen and LH levels were recorded before and after the treatment. Progesterone and estradiol levels were significantly lower before the treatment and progressively increased after the treatment. During late proestrus the serum progesterone levels increased progressively towards LH surge and during estrus, progesterone levels were significantly higher on each day of estrus. Significantly higher estradiol levels were noticed during proestrus and these levels were reduced at the time of LH surge. The LH concentration was recorded as 380.58 + 38.73 ng/ml at the time of LH surge. The LH surge was maintained for two days and thereafter significantly reduced during late estrus and early diestrus. The days taken for induction of estrus were 9.20 + 1.32 in Cabergoline followed by 13.83 + 2.65 in PMSG and 70.83 + 12.42 in Control group of bitches. The inter estrus interval in control group of bitches were longer than the Cabergoline and PMSG treated groups. The duration of proestrus was shorter in Cabergoline treated bitches than Control and PMSG group of bitches. There was no significant difference in the duration of estrus among Control, Cabergoline and PMSG groups of bitches. The therapeutic response to the treatment was 83.33 and 100 per cent in Cabergoline and PMSG treated bitches respectively. The conception rates were 66.66, 83.33 and 83.33 per cent in Control (mated based on vaginal cytology), Cabergoline (mated based on vaginoscopy) and PMSG groups (mated based on progesterone level), respectively. The litter size varied from 3.50 + 1.12 to 4.83 + 0.83 in three groups. Vomiting was observed as a side effect in Cabergoline treated group.
