The accuracy of rectal palpation and ultrasonography for predicting the presence of a functional corpus luteum in subestrous dairy cows was investigated, using the result of a radioimmunoassay for progesterone in plasma. Luteal status (high or low progesterone concentrations) was diagnosed in 820 cows, using rectal palpation and B-mode transrectal ultrasonography, and the results of rectal palpation and ultrasonography were compared in $2{\times}2$ contingency table with plasma progesterone concentrations. A $2{\times}2$ contingency table analysis allowed the calculation of sensitivity, specificity and predictive values for rectal palpation and ultrasonography. The sensitivity, specificity, predictive value of a positive test and predictive value of a negative test were 81.9%, 67.5%, 79.0% and 71.4% for rectal palpation, and 96.3%, 88.8%, 94.5% and 92.4% for ultrasonography, respectively. The percentages of observed agreement and expected agreement between rectal palpation and ultrasonography were 71.8% and 57.1%, respectively. An evaluation of agreement between rectal palpation and ultrasonography, the value of Kappa was 0.34. It was concluded that a ultrasonography was more sensitive and specific than rectal palpation in predicting the presence of a functional corpus luteum. Therefore, ultrasonographic examination is a reliable method for assessing the functional status of ovarian structures in subestrous dairy cows.

Accuracy of rectal palpation and ultrasonography for differential diagnosis of subestrous dairy trows were investigatedl using the result of pIRsma progesterone assay. The ovaries were examined 2 times of 10 days interval in 520 posearom and postinsemination subestroHs dairy cows, using rectal palpation and B-mode transrectal ultrasonography. The results of rectal palpation, ultrasonographic examination and measurement of plasma progesterone profiles in 520 subestrous dairy cows were silent brat or error of estrus detection 303 (58.3%), persistent corpus luteum 59 (11.3%), follicular cyst 37 (7.1%), luteal cyst 16 (3.1%), inactive ovary 9 (1.7%), granulosa tumor 1 (0.2%), hydmsalphinx 1 (0.2%), endomehris 81 (15.6%), pyometra 12 (2.3%) and mummified fetus 1 (0.2%), respectively. Accuncy of rectal palpation and ultrasonography for diagiosing ovarian disordeir based on plasma progesterone profiles were silent heat or error of estrus detection 80.5% and 96.7%$\boxUl$ persistent corpus luteum 57.6% and 94.9%, follicular cyst 62.5% and 91.9%1 luteal cyst 62.5% and 87.5%, maclive ovary 55.6% and 88.9% and granulosa cell tumor 100% and 100%, respectively. Acnuucy of rectal palpation for diagnosing uterine disorders based on ultrasonography was pyometra 75.0%1 endometritis 51.9% and mummified fetus 100%, respectively. Cbaracteristic ultrasonographic appearances of ovaries in subestrous dairy cows were as follows; Silent heat or error of estrus detection: anechoic follicle or hypoechoic corpus luteum than ovarian stroma was alternately present on Day 0 (first examination) and Day 10. Follicular cyst: uniformly nonechogenic ovarian structure $\geq $ 25 mm in diameter with a wall < 3 mm was present in ipsilateral on Day 0 and Day 10. Luteal cyst: luteal cyst was similar to follicular cysts but thickness of cystic wall was $\geq $ 3 mm. Inactive ovary : structures within ovaries was not present on Day 0 Bnd Day 10. Characteristic uthssonograpsc appearances of uterus in subestrous dairy cows were as follows; Endometritis: characterized by uterine lumen containing fluid in which 'snowy'echogenic particles art suspended. Pyometra: ultrasonographic appearance of pyometra was diffuse echogenic particles distributed in fluid within the distended uterus, and a thickened uterine wall. These results indicated that ultrasonography was practical far diagnosing reproductive disorders. To diagnosing ovarian disorders, ultrasonography should be carried out 2 times of 10 days interval and rndometritis should be differentiated with uterus of luteal phase in normal cycling cows.

Ultrasonographic study was undertaken to establish the echogenecity and size of reproductive organs of 18 cycling buffaloes of different parities and compared with the sizes measured by palpation per rectum at estrus (day 0), met estrus (day 2), mid diestrus (day 10) and late diestrus (day 16). The overall mean size of cervix, uterine body, right horn, left horn, right ovary and left ovary measured by palpation per rectum were 2.70$\pm$0.43, 2.36$\pm$0.36, 2.17$\pm$0.37, 2.12$\pm$0.38, 2.63$\pm$0.41 and 2.72$\pm$0.37 cm, respectively. The corresponding ultrasonographic observations were 2.10$\pm$0.40, 1.85$\pm$0.30, 1.73$\pm$0.36, 1.64$\pm$0.37, 2.16$\pm$0.36 and 2.29$\pm$0.38 cm respectively. Variations in the size of genitalia due to stages of estrous cycle were non-significant. The size of genitalia measured by palpation per rectum was significantly higher (p<0.05) than by ultrasonography. However, there was linear positive correlation (r=+0.87) in the measurements by the two techniques. The ultrasonographic characteristics of tubular genitalia revealed different echogenic gray shades around the nonechogenic (black) central area of lumen depending upon the stage of cycle. The ovarian stroma appeared as hyperechoic (white) area with nonechogenic (black) follicle. The corpus luteum (CL) exhibited different echogenic texture viz. grayish black, grayish granular and grayish white at met estrus, mid diestrus and late diestrus, respectively. Therefore, ltrasonography can be effectively employed to record the exact size and echotexture of the buffalo genitalia during different stages of estrous cycle.

Plasma progesterone concentrations in 44 suckling Korean native cows were determined to monitor ovarian activity postpartum by radioimmunoassay. Blood samples were collected in 3 day intervals from 15 to 80 days postpartum. The ovaries and uterus were examined in 6 day intervals by rectal palpation. Results are summaried as follows: 1. The cows were qualified into four categories; Type I(normal): cyclic changes in plasma progesterone concentrations appear within 45 days postpartum(35 cows, 79.5%), Type II(cycle delayed): delayed resumption of ovarian activity by 55 days postpartum(5 cows, 11. 4%), Type III(cycle ceased with low progesterone): plasma progesterone concentrations remained low(${\leq}1ng/ml$) until 80 days postpartum(3 cows, 6.8%), Type IV(cycle ceased with high progesterone): plasma progesterone concentrations after 30 days remained high(${\geq}4.0ng/ml$) until 80 days postpartum(1 cow, 2.3%). 2. Out of the cows classified Type II and III, 7 cows had inactive ovaries and a cow had follicular cyst by rectal palpation. The cow of Type IV was diagnosed as bearing persistent corpus luteum by rectal palpation. 3. About 82% of the cows showed significant rises in plasma progesterone concentrations prior to 50 days postpartum and the cows of Type II and III resumed cycles in 31. 6(range 17~55) days after calving. However, 43.2% resumed cycles in 50 days postpartum by estrus signs. These results indicated that plasma progesterone concentrations assessed by radioimmunoassay can be utilized for monitoring postpartum ovarian activity and would be helpful for the early detection of ovarian dysfunction in the Korean native cow.

Various early pregnancy diagnostic methods have been developed in order to improve the reproductive efficiency in cow, mare, mule, sow, sheep, goat, dog, cat, rabbit, buffalo, camel, elephant, monkey, deer, lion, coipus and guinea pig. These methods include abdominal swelling, abdominal palpation, esturs cylce detection, Lupin test, gonadotropin assay, colostrum injection test, sperm motility assessment, cervical mucus viscosity test, Kaber chromagens method, estrogen test, A Scheim-Zond다 test, spectrophotometric detection of estrogen in urine and feces, boric acid crystraline formation test in urine, oxytocin injection test, diamino-oxidase test, PMSG HA test, behaviour test, Simolus iodine detection test, detection of tryptophane in urine, x-ray method, Cuboni and Lunaas method, vaginal biopsy method, Friedmann Schneider diagnostic method, electrode method, barium chloride detection method, ECG, Doptone method, ultrasound method, ultrasound scanning method, LDH method, rectal palpation method, CL palpation method, radioautography, serum creatine test, serum globulin test, chlormadine method, CAP method, Medata Do, pp.ers method, body fluid test, Plasma oCS detection method, ERIA, LHRH method, negative latex cogulation test and oestrone sulphate detection method. The most reliable methods with high a, pp.icability to farm animals such as sheep, mare, sow and cow are rectal palpation, ultrasound method and hormonal assay in blood and milk. However, they require complicated laboratory works for the early diagnosis of pregnancy and in most cases, the simple and economical methods which are described up to now need a long period of time after conception. Generally, it is possible to detect pregnancy after one estrus cycle, even though it varies depending on the species of animals. For improvement of the reproductive efficiency, it is required to develop a more accurate, economical, simple and early detectable method. It is anticipated that the result of a study on the detection method of EPF(early pregnancy factor) would be a, pp.icable to various animals within 6 hours after conception.

From September 1993 to August 1997, we treated ovarian disorders in 1,782 repeat breeder cows after diagnosis by ultrasound on 35 farms in Kyeong-ki do. The rates of ovarian appearance were 59.8% of CL group, 16.7% of ovarian atrophy or hypofunction, 15.4% of luteal cyst, 4.3% of follicular cyst and 3.7% of follicle group in diagnosis with rectal palpation and ultrasound. The results of treatment for ovarian disorders were 1,316 cows(73.8%) in estrus, 348 cows(19.5%) in non-detected and 118 cows(6.6%) in unidentified. The rates of PGF$_2$$\alpha$, GnRH and mineral vitamin complex treatment to estrus were 79.6, 69.2 and 50.3%. Two groups were treated with 5 ml PGF$_2$$\alpha$ intramuscular injection(I.M.) and 1.5 ml PGF$_2$$\alpha$ intraovarian injection(I.O.), and the results of 1.5ml PGF$_2$$\alpha$ I.0. were significantly higher than that of 5ml PGF$_2$$\alpha$ I.M. in inductiom estrus(p<0.05). The pregnant rates were 29.8% in total repeat breeder cows with ovarian disorders following diagnosis and treatment. In summary, rectal palpation and ultrasonography were proven to be useful tools of diagnosis and treatment in ovarian disorders, and it was also suggested that the response to treatment with PGF$_2$$\alpha$ I.0. was better than PGF$_2$$\alpha$ I.M.

In order to investigate reproductive disorder in dairy cows, 312 uterine from abattroirs and 56 cows from dairy farms were examined. The ovary and uterine were collected from abattroirs and rectal palpation was carried out in the case of reproductive disorder at dairy farm. Microbiological examination was also carried out from the collected samples. 1. Out of 312 ovaria from slaughter-house, cystic ovary and endometritis were classified as 51(16%) and 134(43%), respectively. And of 56 dairy cow from farms, 43(77%) were identifies as endometritis. 2. The main cause of reproductive disorder was classified as hormonal imbalances, endometritis and cystic ovary, singly or in combination. 3. The main causative agents of endometritis was encountered as E coli, Staphylococcus aureus, Bacillus sp and Corynebacterium sp. 4. The highest susceptible antibiotics to the isolates was cephalosporin.
