Abstract

The objective of the present study was to predict gestational age of female dogs by real time ultrasonography using measurements of placental thickness, evaluating the correlation between observed and calculated gestational age as well as the accuracy of placental thickness measurement (Biometry) with fetal morphologic parameters in bitches. Bitches were divided into 3 groups, small, medium and large and total 30 bitches were taken and examined at 20-30 days, 30-40, 40-50 and 50-60 days interval. Gestational age was calculated by using gestational equations derived from the linear regression analysis. The expression that presents the best correlation coefficient and explanation for thickness of placenta “Y= 0.021x-0.314”. Results clearly demonstrated that biometric parameter placental thickness significantly (p<0.05) correlated with gestational age (r =0.973) and was a reliable index to predict gestational age in bitches.
