  • Serial ultrasonographic examinations were performed on pregnant Korean Jindo bitches. Measurements of inner chorionic cavity diameter and fetal head diameter were made from pregnancy day 15 to parturition. These measurements were converted retrospectively based on the day of parturition (day 0). The data of inner chorionic cavity diameter obtained from day -42 to day -25 and fetal head diameter obtained from day -24 to day -1 were used to prediction of parturition day. Formulas for the prediction of parturition day using the method of least squares were derived. These formulas were then used to predict parturition dates based on single measurements of inner chorionic cavity diameter or fetal head diameter in 17 additional pregnant Korean Jindo bitches. Predicted date of parturition was then compared to actual whelping date. In the prediction of parturition based on inner chorionic cavity diameter, 7 of 10 bitches were coincided prediction date and actual whelping date, and the prediction was accurate to within 1 day in 3 of 10 bitches. The prediction of parturition based on fetal head diameter was accurate to within 1 day in 6 of 7 bitches and within 2 days in 1 of 7 bitches. In conclusion, the ultrasound measurement of inner chorionic cavity diameter and fetal head diameter are practical and accurate tool in the prediction of parturition.

  • Microsatellite allele analysis has been used for individual identification and paternity test. In the present study, the biological father of three puppies was determined by using microsatellite allele amplification analysis. The mother bitch of the litter was a Poongsan dog. The three stud dogs that could have inseminated the bitch, by being in the same residence, were a white Poosan dog, a mixed breed, and a white Jindo dog. DNA was obtained from all the relevant dogs by buccal swabbing. Four loci of tetranucleotide repeat microsatellite were PCR-amplified, and analyzed by polyacrylamide gel electrophoresis and silver staining. The results of genotyping unambigously assigned the Poongsan dog as the biological father. There was no evidence of superfecundation. Therefore, the present study demonstrated the usefulness of microsatellite allele analysis as a simple, efficient method of paternity test in dogs.

  • The present study was carried out to investigate the estrous behavior and vaginal smear after induction of estrus with exogenous hormones in the premature, metestrous and anestrous bitches. A total of 21 bitches(Mixed breed: 16, Jindo breed: 5), from 10 months to 5 years of age and weighing 8 to 15 kg was studied the change of vaginal smear and the estrous behavior before and after induction of estrus. The results obtained are as follows: 1. In the treatment A(They were given the $PGF_2{\alpha}$, estrone, estradiol-$17{\beta}$, PMSG and HCG) proestrus commenced in $10.16{\pm}1.44$($Mean{\pm}SEM$) days after treatment, The mean duration of proestrus, and estrus was $7.50{\pm}1.44$ and $13.50{\pm}3.44$ days, respectively. In the treatment B(They were given the PMSG and HCG) proestrus commenced in $5.53{\pm}0.59$ days after treatment. The mean duration of proestrus and estrus was $6.60{\pm}0.71$ and $14.60{\pm}1.14$ days, respectively. 2. All of the 6 bitches in the treatment A showed vulval swelling and vaginal discharge, 14 of the 15 bitches in the treatment B showed vulval swelling and vaginal discharge. However, all of the treatment A and B showed male acceptance. 3. The main change of vaginal smear in proestrus and estrus after induction of estrus was a increase in the proportion of anuclear and superficial cells associated with a decrease in small intermediate and parabasal cells. By the estrous behavior and vaginal smear the estrus was induced in all the premature, metestrous and anestrous bitches.
