Diagnosis and treatment of major reproductive failures were carried out for 836 dairy cows of 12 farms in Kimje area from May 1999 to May 2000. Reproductive failures were classified into four categories: uterine diseases, ovarian diseases, combination of uterine and ovarian diseases, and anestrus with corpus luteum (CL), based on the diagnosis by both rectal palpation and ultrasonography (SA 600, Medison, 5.OMHz transducer). 1. Of 102 cows examined, 15 cows were diagnosed as pregnant. Cows with real reproductive failures were therefore 87 cows and the rate of reproductive failures far all the cows of 12 farms was 10.4% (87/836). 2. Of 57 cows with reproductive failures, the cows with uterine diseases were 33 heads (37.9%), with ovarian diseases: 30 heads (34.5%), with combination form: 16 heads (18.4%), and with anestrus with CL: 8 heads (9.2%). 3. Of 87 cows with reproductive failures, 7 cows were slaughtered and 80 cows were treated by hormone or douche. The cows expressed estrus were 74 cows (92.5%, 74/80 heads) and 56 cows were pregnant (70.0%, 56/80 heads) following treatment. 4. The reproductive failures tended to be increased as the period proceeded from 30 days (2.3%, 2/87 heads) to over 120 days (56.3%, 49/87 heads) after parturition. 5. Associated other diseases to reproductive failures were foot diseases(5 cows), joint diseases (5 heads), urovagina (6 heads), and rectovaginal fistula (2 cows) and the rate of occurrence of associated diseases was 20.7% (18/87 heads). 6. No reproductive record was used in 7 farms of 12 farms and 5 farms had no play ground or not used for the cows. These results indicated that diagnosis fur reproductive failures by rectal palpation along with ultrasonography was more accurate than the conventional rectal palpation and brought better result of treatment for major types of reproductive failures. It was also indicated that non-uses of reproductive record and play ground were also important factors in occurrence of reproductive failures.

최근 적절한 사양관리를 위해서 유중 요소태질소 수준(MUN)과 유단백을 이용하여 사료 내 에너지와 단백질의 균형을 평가하는 지표로 활용하고 있으며 요소태질소 수준이 정상보다 크게 높거나 낮았을 때 번식능력이 저하되기 때문에 번식효율의 지표로서 활용되고 있다. 따라서 본 연구에서는 우유내 요소태질소 수준이 번식장애에 미치는 영향을 조사하여 요소태질소 수준을 번식장애의 진단지표로 활용하고자 실시하였다. 본 실험에 공시된 우유시료는 경기도 안성시와 이천시에 소재한 낙농목장에서 사육중인 조사두수를 대상으로 개체당 약 30~50$m\ell$의 우유를 채유하고 냉장보관하여 실험실로 운반하였다. 우유의 분석은 유성분분석기(Fosscomb : 4000, Fossmatic 5000, Denmark)를 이용하여 우유의 일반성분인 유지방, 유당, 유단백, 무지고형분, 총고형분, 빙점, 유중요소태질소, 구연산과 체세포를 동시에 분석하였다. 번식장애우의 진단은 낙농가가 번식장애우로 분류한 개체를 대상으로 직장검사 및 초음파 진단기를 이용하여 진단하였다. MUN준에 따른 공태일수의 조사 결과 MUN수준이 7이하 군의 공태일수가 88.98$\pm$120.68로 7-16의 92.20$\pm$105.39와 16이상의 94.42$\pm$87.51보다 다소 낮은 결과를 나타냈다. 또한 번식장애우의 발생빈도와 유성분 분석결과를 살펴보면 낙농가가 번식장애우로 분류한 68두를 진단한 결과 발정발견을 하지 못하여 번식장애우로 분류된 두수가 30두(44.1%)와 비정상두수 38두(55.9%)로 나타났으며 비정상 두수 중 난포난종이 19두(27.9%)로 영구항체6두(8.8%), 자궁내막염(10.3%), 자궁축농증 6두(8.8%)보다 많은 것으로 나타났다. 번식장애우의 유성분 분석결과 자궁축농증이 있는 개체의 유단백 평균이 3.43$\pm$0.35로 다른군에 비해 높았으며 영구항체가 있는 개체군의 MUN수준이 7.73$\pm$8.58로 다른군의 10.84$\pm$4.92, 10.89$\pm$7.38와 10.61$\pm$5.52에 비해 낮게 나타났다.

암캐에 있어서 번식장애의 병력이 있는가를 검사하는 것은 상당히 어려운 문제이다. 많은 축주들은 번식장애를 일으킨 암캐들 중의 어떤 개를 소유하게 되었을 것이며 이는 과거에 의학적 문제에 관한 정확한 지식도 가지고 있지 않을 수 있으며 불안전한 상태 일 수도 있기 때문이다. 동물을 소유한 축주로부터 병력을 알았다고 할지라도 올바른 평가를 하는데 도움이 되지 않을 수도 있으며 많은 거리가 있을수도 있다. 그러나 병력을 통하여 적당한 진단계획을 세우는 것이 많은 가치가 있다면 병력을 얻는데 모든 노력을 기울여야만 한다. 병력은 동물의 번식능력에 대한 기록, 발정주기, 발정간의 기간, 음부의 분비물, 과거 분만 곤란 및 강아지의 생존률 등이 포함되어야 할 것이다.

돼지의 번식장애는 전염성과 비전염성으로 나눌수 있는데 전염성에는 세균,진균,병독 등이 있고, 비전염성에는 번식모돈의 사양환경 사료 급여 등의 실의로 인한 성호르몬 대사의 난조와 생식기 질환 등으로 많은 모돈이 도태된다.

This study was carried out to investigate the reproductive status and the effect of progesterone treatment on the recovery of reproductive disorders in Hanwoo. Hanwoo farms were surveyed the general management status, such as the type of barn, the feed intake, the incidence of reproductive disorders. The reproductive disorder cattle were treated 7 days insertion of control internal drug releasing for cattle (CIDR) and injection of PGF$_2$$\alpha$ at 1 day before removal. The recovery of reproductive disorders was assessed by determining the pregnancy following artificial insemination. The total number of surveyed Hanwoo farms was 127, and the total incidence rate of reproductive disorders was 19.7% (209/1,061). Compared to the herd size, the incidence rates of reproductive disorders in less than 10 heads (37.5%) was significantly (P<0.05) higher than in 10 to 20 heads (14.7%) and more than 20 heads (13.6%) of herd size per farm. The incidence rate of reproductive disorders in tie stall barn was significantly (P<0.05) higher than in free stall barn (30.4% vs. 14.7%), and even in free stall barn, that tended to decrease as the floor area was larger. The incidence rate of reproductive disorder by the parity was highest in heifer (50.7%), and that tended to decrease as the parity was increased. The distribution rate of the case of reproductive disorder in anestrus, recovery rate of reproductive disorders fellowing CIDR treatment was 75.1% (157/209). In the recovery rate of reproductive disorders by body condition score (BCS), BCS 1, 2 and 3 was significantly (P<0.05) higher pregnancy rate (85.7, 84.9 and 86.8%), and gross recovery rate in emaciated cattle was better than in obese cattle (BCS 4, 5). In conclusion, the incidence rate of reproductive disorders in Hanwoo raised in Youngju province area was 19.7%, and that tended to decrease as the herd size was increase because of increased farmer's attentions, and the floor area was larger. The majority of the case of reproductive disorders was anestrus. The recovery rate of reproductive disorders following CIDR treatment was 75.1%, and to optimize the recovery rate of reproductive disorders, cows and heifers were maintained BCS 1, 2 and 3 by moderate management.

This survey was carried out to investigate the occurrence of reproductive disorders in Korean native cattle (Hanwoo). The general management status such as barn type, feed intake, parity and type of reproductive disorders were examined in the Hanwoo farms. In this survey, the total incidence of reproductive disorders that was assessed from 54 Hanwoo farms was 11.6% (73/ 631). We first examined the incidence of reproductive disorders following herd size per farm. The rates of reproductive disorders in under 10 heads, 10 to 20 heads and over 20 heads were 25.2%, 9.4% and 8.3%, respectively (P<0.05). The rate of reproductive disorders in tie stall barn was significantly (P<0.05) higher than that in free stall barn (14.9% vs. 8.1%). The major types of reproductive disorders were follicular cysts (21.8%), fat necrosis (21.8%), and repeat breeding (17.8%). The rate of reproductive disorders assessed by the parity tended to decrease as the parity increased. The relationship between incidence of reproductive disorders and body condition score (BCS) was investigated in 203 Hanwoo. The incidence of reproductive disorder was 80.0%, 8.8%, 9.4%, 10.0%, 33.3% and 57.1% at 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 of BCS, respectively. These data show that the increase of herd size, barn type and BCS affect the incidence of reproductive disorders such as follicular cysts, fat necrosis and repeat breeding in Hanwoo.

(주)서일가축약품(대표 신지식)은 1981년 낙농기계 업체로 출발했다. 이후 서일낙농으로 이름을 바꾸며 낙농 자재 등을 주로 유통 판매해오다 약품관련 업종을 추가하면서 지금의 '서일가축약품'에 이르게 됐다. 유럽에서 각종 질병과 번식장애 등에 탁월한 약품들을 독점 계약으로 수입 공급하고 있는 (주)서일가축약품을 찾아가 봤다.
