A clinical study was designed to record the conception rate in bitches after mating at different intervals after the onset of peak vaginal cornification. It was observed that the first day of peak vaginal cornification correlated poorly with the genital and behavioral changes suggestive of estrus. The genital and behavioral signs of standing estrus were observed in significantly more number of animals on day three after the optimum vaginal cornification However, on day 5 only 50 per cent of the animals exhibited genital and behavioral signs of estrus and on day seven, many refused to stand. The best conception rate was recorded when the animals were recommended to be mated starting on day three after the onset of peak vaginal cornification. It appears that the LH surge is likely to occur between days two and four after the onset of peak vaginal cornification. The ideal time of mating is recommended on the basis of vaginal exfoliative cytology that would be on day two and four when two matings are planned and mating is suggested on day three when a single mating is planned after the onset of peak vaginal cornification.
