PROGESTERONE PROFILES AND CHANGE IN RECTAL TEMPERATURE IN INDUCED WHELPING BITCHES

Abstract

The present study was conducted in 29 clinical cases. Whelping was induced by using cloprostenol,
dinoprostone plus cloprostenol and mifepristone plus cloprostenol. The mean duration of time interval from
starting of treatment to beginning of whelping was 34.46 ± 4.70, 40.48 ± 6.47and 26.98 ± 4.51 hours in three
treatment groups respectively. The mean plasma progesterone concentrations were 3.89 ± 0.54, 3.54 ± 0.31,
2.72 ± 0.41 and 3.83 ± 0.2 ng/ml before starting of treatment; 1.92 ± 0.13, 1.86 ± 0.12, 2.87 ± 0.5 and 1.55 ±
0.21 ng/ml at 2 to 12 hours before whelping and 0.56 ± 0.06, 0.53 ± 0.08, 1.18 ± 0.4 and 0. 7 4 ± 0.13 ng/ml
during O to 6 hours after whelping in three treatment groups respectively. The mean rectal temperature was
101.23 ± 0.20, 101.62 ± 0.17, 101.86 ± 0.30 and 102.08 ± 0.08 °F before starting of treatment; 99.98 ± 0.53,
100.85 ± 0.28, 101.43 ± 0.35 and 100.5 ± 0.22 °F at 12 hours after treatment; 99.94 ± 0.21, 100.15 ±0.3,
101.5 ± 0.38 and 99.95 ± 0.24 °Fat 24 hours after treatment; 100.75 ± 0.48, 101.79 ± 0.10, 101.88 ± 0.32 and
101.3 ± 0.14 °Fat 36 hours after treatment and 101.5 ± 0.75, 102.0 ± 0.5 and 101.8 ± 0.16 °Fat 48 hours after
treatment in cloprostenol, dinoprostone plus cloprostenol, mifepristone plus cloprostenol and control groups
respectively.
