“…Ultrasonographic fetometry is commonly applied for the assessment of foetal growth during canine pregnancy. In different weight or breed groups of dogs, this method has been thoroughly investigated, and the measurement of extrafoetal or foetal structures allowed to prognose parturition day with formulas generated from the growth curves of selected parameters (Kim, Travis, & Meyers‐Wallen, ; Lopate, ; Luvoni & Beccaglia, ; Kim & Son, ; Lenard, Hopper, Lester, Richardson, & Robertson, 2007).…”

The aim of this study was to derive the growth curves of the inner chorionic cavity and the biparietal distance in miniature dog breeds by ultrasonographic fetometry and present new specific formulas for prediction of parturition date. In this study, foetal biometry parameters were obtained using serial ultrasonographic examinations in 24 pregnant bitches of six different miniature breeds (≤5 kg). The mating time was unknown. Overall, 25 inner chorionic cavity diameter (ICC) and 22 biparietal diameter (BP) measurements were taken. The relationship between ICC or BP growth and days to parturition was analysed by linear regression. The results showed a significant relationship between days before delivery and ICC or BP. The equations derived from the growth curves can be used in practical prediction of parturition date in miniature dog breeds.

Predicting the parturition date in dogs by taking ultrasonographic foetometry has opened interesting research areas of veterinary obstetrics. Recently developed calculation formulas of inner chorionic cavity diameter (ICC) and biparietal diameter (BP) are formulas by Luvoni and Grioni (2000). This study is one of the first reports referring to ICC and BP with the use of Luvoni and Grioni formulas for predicting the parturition time in dogs of different body weight in clinical practice conditions. The research material consists of 70 clinically healthy pregnant bitches of 27 breeds and cross-breeds. Bitches were divided into 4 groups according to their body weight. In each of the bitches, ultrasonographic examination of pregnancy was performed at least twice (ICC and BP measurements). Parturition dates for dogs with a body weight over 25 kg were calculated based on formulas intended for the group of medium dogs. It was caused by the lack of appropriate formulas for these groups of dogs. The predicting parturition dates were compared with the actual dates of delivery provided by the bitch owners. Generally, the results obtained in this study are very encouraging and similar or even better than those published by other authors using foetometric measurements. In our research, when comparing the effectiveness of predicting the delivery date based on foetometric formulas by Luvoni and Grioni (2000), it was proved that in all groups of dogs, even those over 25 kg, ICC and BP measurements at both accuracy levels were characterized similar reliability.

“…The time of ovulation should be accurately determined for the artificial insemination of bitches because frozen spermatozoa rapidly lose their vitality (7,10). Vaginal cytology cannot accurately predict the time of ovulation and is therefore not effective in artificial insemination (6,10).…”

“…This method is not satisfactory given that the ovulation time is not fixed in the 5 to 30 day period of estrous. Therefore, various methods for predicting ovulation, including serum or plasma hormone concentration, vaginal cytology, vaginal electrical impedance (VEI), vaginal endoscopy and ultrasonography (USG) evaluation of the ovary, have been employed (3,7,9,10).…”

SummaryA study was carried out to compare the efficiency of vaginal electrical impedance with serum progesterone profile, cytological examination and clinical findings. Vaginal electrical impedance values varied at the different stages of the estrous cycle, with the highest value during the transition into estrous and the lowest in diestrus (P < 0.05). There was a negative statistical correlation between serum progesterone values and the impedance values (36%) (P < 0.001). Vaginal electrical impedance was a faster and cheaper method than progesterone assessment. It was more reliable than vaginal cytology and clinical evaluation. In conclusion, a combination of vaginal electrical impedance measurements and progesterone evaluation was a more useful method for determination of the optimal breeding time in bitches.
