Abstract

The gestation period and parturition days were accurately predicted by measuring progesterone concentration in the plasma from 40 pregnant companion bitches. The mean length of the estrous cycle based on plasma progesterone concentrations were 8.14 ± 1.39 (Mean ± SD) days for proestrus, 9.19 ± 2.01 days for estrus, and 55.38 ± 1.96 days for diestrus phase, respectively. The gestation length from each based on the days was 65.61 ± 2.47 days from the first day of estrus after the first vaginal discharge, 63.21 ± 0.99 days from the day when plasma progesterone concentrations increase above 4.0 ng/ml, and 54.51 ± 3.51 days from the first day of diestrus, respectively. Therefore, the parturition day was estimated 65 days from the first day of estrus after the first vaginal discharge, 63 days from the day when plasma progesterone concentrations increase above 4.0 ng/ml, and 54 days from the first day of diestrus, respectively.
