본 연구에서는 비디오 감시 시스템을 기반으로 한우 축사에서 야간 승가 행위 검출을 위한 최적의 방법을 제안한다. 특히 축사 환경에서는 소들간의 겹침 등 다양한 어려움이 발생하기 때문에, 이를 극복하기 위하여 깊이 정보를 이용하여 승가하는 소의 머리를 자동으로 탐지한다. 즉, 소가 네발로 걸어다니는 통상의 경우 소의 등 높이가 1.3m 정도인데 반해 앞발을 들어 승가하는 경우에는 소의 높이가 1.7m 까지 높아짐에 착안하여, 축사 측면에 설치된 깊이 카메라로부터 소까지의 거리 차이를 이용하면 발정기 탐지를 위한 승가 행위를 자동으로 검출할 수 있음을 확인하였다.

In dogs, correct diagnosis of estrus is important and the exact time of ovulation can be determined by variouse methods. Vaginal cytology has commonly used in conjunction with the physical examination, clinical history, vaginoscopy, and hormonal assays to determine the stage of the reproductive cycle. This study was therefore investigated the effectiveness of direct ovulation detector designed by changes of electrical resistance in vaginal mucus following different estrus cycles with several methods; vaginal cytology, concentration of plasma estrogen and progesterone, and direct examination by laparotomy. A total of 12 bitches was selected for the study and observed estrus signs. The bitches were evaluated clinical sign (vulvar swelling and bleeding), cytological examination (keratocyte and RBC), electrical resistance, plasma estrogen and progesterone concentration for estrus assessment. Accuracy of ovulation detection by vaginal cytology was significantly (p<0.05) lower than those by electrical resistance and plasma progesterone concentration, based on the confirmation by laparotomy. Vaginal smear is not confidential method compared to detection of electrical resistance and plasma progesterone concentration at ovulation. Although the value of electrical resistance was varied at the same points of estrus in individuals, ovulation was occurred at the first day which shown the peak of electrical resistance and mating time was third day after peak. In conclusion, ovulation detector designed by changes of electrical resistance is an effective and economic instrument for predicting estrus and ovulation in bitches.

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.

An uterus is female reproductive tract organ that affected estrus cycle. During a various changes occur at uterus in estrus cycle, one of them is body fluids secretion be called uterine fluid. Therefore, the objective of this study was to investigate the changes of protein patterns using two-dimensional gel electrophoresis in uterus fluids during the follicular and luteal phases in estrus cycle of pigs. In changes of protein spots were confirmed during the follicular and luteal phases. The 136 spots were expressed in follicular phase, the 57 spots of them showed reproducibility. On the other hand, the 140 spots were expressed in luteal phase, the 73 spots of them showed reproducibility. Also, spots expressed in follicular phase were number 69 and 94 spots and spots expressed in luteal phase only were number 156, 157, 184~187, 190 and 191 spots. The spots which of higher expression levels in the luteal phase than in follicular phase were number 76 and 79 spots. In conclusion, the spots expressed in follicular and luteal phases were confirmed with difference levels and these differences are function of RNA resolving, protein synthesis and cytoskeletal architecture.

To describe the macroscopic anatomy and ovarian-physiological difference of the genital organs of the female Korean water deer, organs from captured animals in a wild area of Korea were dissected. The ovary of estrus group was about $1.10{\pm}0.02mm$ long and weighed about $0.50{\pm}0.02g$. And pregnant group was about $1.3{\pm}0.10mm$ long and weighed about $0.40{\pm}0.05g$. And the crowns of corpora lutea were found in the estrus group, but we couldn't find crowns at the pregnant group. Especially, the estrus ovaries tended (p=0.04) to be heavier than the ovaries during pregnancy. The MMP-9 activity was higher at the Graafian follicles of pregnant group than that in estrus group. However, with regard to follicles of estrus group, MMP-2 level was higher than that in pregnant group. Furthermore, apoptosis detection marker (Casp-3) was highly expressed in Graafian follicle of the pregnant group and the corpora lutea of estrus group. Thus, the differential expression of MMPs observed in this study suggests that the reflected the mechanisms underlying of monovulatory in estrus and/or pregnancy. Our results may be very useful as it provides with information that may be considered for the development of reproductive biotechnologies in endangered animals.

The aim of this study was to assess the precision of the estimates of the time of estrous cycle, optimal breeding and ovulation derived by vaginal cytology. The thirteen Korea Jin-do dogs were examined the vaginal cytology, plasma estradiol-17$$\beta $ and progesterone assay during the estrous cycle. Day 0 was the day of the first male acceptance. The main change of vaginal cytology during the estrous cycle was the high proportion of anuclear cell and erythrocyte in proestrus, superficial cell, anuclear cell and erythrocyte in estrus, parabasal cell, large intermediate cell and leukocytes in diestrus, and parabasal cell and small intermediate cell in anestrus, respectively. These data indicated that vaginal cytology was reliable method for estimating estrous cycle in Korea Jin-do dogs. In the cell indices during estrus the maximum eosinoghilic index was $92.0{\pm}$2.6 (Mean{\pm} SEM$)% at Day 2 and the maximum cornification indez was $96.0{\pm}1.3%$ at Day 2, respectively. The eosinothilic indez and cornification indez of up to 70% were found at Day -1 to Day 5 and Day -6 to Day 8, and up to 80% at Day 1 to Day 4 and Day -4 to Day 6, respectively. From these data it was presumed that eosinophilic index was more reliable index for monitoring optimal breeding time than cornification indexm because eosinophilic index peak period was shorter than cornification indeX peak period and Day 2 was the day of ovulation. Therefore, optimal breeding time was the eosinophilic index peak period, more than 80% of eosinoghilic index. The $estradiol-17{\beta}$ peak, with 3 days delayed when progesterone concentration was $4.5{\pm}0.5 ng/ml$. These data estimated that the ovulation time was the day of eosinophilic index peak, Day 2. breeding time and pvulation time in Korea Jin-do dogs.
