  • On January 6, 2010, two months earlier than normal breeding season, a red fox vixen was implanted with synthetic GnRH analogue, Deslorelin. Blood was sampled every 2~3 days from the day of implant to identifying spermatozoa on stains of epithelial cells. Estradiol and progesterone were examined. Even though the vixen was in non-breeding season, she was mated by a male fox. Pregnancy was confirmed by canine pregnancy detection kit that detect relaxin released from placenta. Four healthy pups were born on March 9, 2010. This is the first report showing synthetic GnRH can activate ovarian function and lead to fertile estrus of red fox in non-breeding season.

  • Eight female Himalayan tahrs (Hemitragus jemlahicus) were estrus-synchronized, and transcervically inseminated with frozen-thawed semen in September, 2009, about 2 to 3 months earlier than their natural breeding season. Intravaginal progesterone-releasing devices were inserted into vaginas of six Himalayan tahrs on September 7, and the other two on September 8 to suppress luteal function of ovaries. The devices had been placed deep inside the vagina prior to withdrawal on September 23. A day before CIDR removal, a combination of PMSG 400 IU and hCG 200 IU was intramuscularly injected. Forty hours later, frozen-thawed semen was transcervically inseminated. Pregnancy diagnosis was performed 39 days later by analyzing progesterone level of serum. Every treatment was done under anesthesia inducted by xylazine injection. In conclusion, vaginal discharge of cervical mucus, hormonal changes induced by implant-typed or muscularly injectable hormones and widening of cervix enough to insert an insemination gun into uterine body were achieved in non-breeding season. Moreover, the first inseminated Himalayan tahr, 36 hours after CIDR removal was assumed to be pregnant but the fetus may have been lost due to the use of anesthetic drug.

  • To establish a protocol of estrus induction and synchronization in European mouflon, we performed artificial insemination using frozen-thawed semen and exogenous hormones. CIDR was inserted into vaginas of four mouflons for 16 days. A day before removal of CIDR, PG 600 was injected intramuscularly. $PGF_2{\alpha}$ was injected when removing CIDR. Artificial insemination was cervically conducted with injecting LHRH 48 hours after CIDR withdrawal. Even though no pregnancy was confirmed, estrous signs were notified like open cervix, congestion of vaginal wall and discharge of cervical mucus. Further research in the wild sheep would be needed for development of artificial breeding methods and advancing sustainability of domestic zoos.

  • This is about the successful use of eCG and hCG for producing a Siberian tiger pup born from 10-year-old, primiparous, albino Siberian tiger. From February 2010 to July 2010, natural breeding had been tried three times with no conception. During this period of five months, estrus behaviors appeared to be typically normal and a lot of matings were observed. After consecutive failures, 1000 IU eCG (equine chorionic gonadotropin) were intramuscularly injected on the day showing estrus behavior, followed with an injection of 750 IU hCG (human chorionic gonadotropin) 80 hours later. The tiger stopped recurrence of estrus, and a cub, weighed 780 gram, was born alive 104 days after hCG injection. This study is the first report showing the unique, successful use of exogenous hormones as one of artificial breeding programs in the long history of captive breeding of carnivorous zoo animals in Korea.

  • 서울동물원의 4세령, 초산 그물무늬기린이 난산 상황에서 특별한 보정장치 없이 수컷 새끼기린을 분만하였다. 어미 기린은 7시간 이상 외음부에 새끼 기린의 앞발이 나온 상태에서 분만의 진전 없이 난산 위기에 처해 있었다. 외음부에 나온 태아 앞발 중수골에 로프 올가미를 한 후 잡아당겨 반대쪽 발목을 견인하였다. 한 개의 로프 올가미를 더 만들어 반대쪽 발목에 걸어 어미 기린의 자궁수축 리듬에 맞춰 로프를 잡아당겨 건강한 새끼 기린을 얻었다. 분만 후 어미 기린은 정상적으로 새끼를 돌봐주었고 분변 내 호르몬 수치를 검사한 결과 분만 후 프로제스테론 수치는 분만 전 상태로 떨어졌다.

  • Four estrus-induced Himalayan tahrs (Hemitragus jemlahicus) were inseminated with frozen-thawed semen by laparoscopic or transcervical insemination techniques with no regard to the site of ovulation in non-breeding season. In June and July, 2009, estrus was synchronized by Eazi-Breed $CIDR^{(R)}$ (Controlled internal drug release; Pfizer Animal Health, New Zealand) insertion for 16 days and PG 600 (PMSG 400IU, hCG 200 IU; Intervet, Netherlands) injection (IM) a day before removing $CIDR^{(R)}$. Forty eight hours later, laparoscopic or transcervical insemination was done to each of two tahrs under anesthetic condition inducted by ketamine (1.5 mg/kg) and medetomidine (0.09 mg/kg). For examination of estradiol and progesterone, blood was collected right before $CIDR^{(R)}$ insertion, PG 600 injection, $CIDR^{(R)}$ removal and insemination. Estradiol levels of four tahrs (No. 1, 2, 3, 4) before $CIDR^{(R)}$ insertion and insemination were 13.3, 8.8, 14.3, 12 pg/ml and 23.5, 25.5, 21.1, 11.5 pg/ml, respectively. Progesterone levels of four tahrs (No. 1, 2, 3, 4) before $CIDR^{(R)}$ insertion and insemination were 1.8, 0.05, 0.63, 0.61 ng/ml and 1.03, 0.37, 1.48, 2.12 ng/ml. Except for No. 4 tahr, cervices showed cervical mucus and opened enough to penetrate with embryo transfer gun sheet usually used for cows. Therefore, No.4 was laparoscopically inseminated together with No. 1. In conclusion, none of four Himalayan tahrs was pregnant. However, we proved that estrus could be induced by CIDR and PG 600 injection in non-breeding season, and laparoscopic or transcervical insemination with frozen-thawed semen could be one of assisted reproductive techniques in Himalayan Tahr.

  • Clostridial bacteria are zoonotic agents, which cause severe necrotizing enteritis, pseudo-membrane colitis, enterotoxemia to both humans and animals. The objective of this study was to monitor the antibiotic resistance of Clostridium isolates on clinical specimens from wild animals in Seoul zoo for 5 years. Clostridium isolates were verified by using Vitek2 compact machine. Antibiotic susceptibility was assessed by antibiotic disc diffusion test, which was followed by Kirby-Bauer disc diffusion test method. The frequency of Antimicrobial resistance of Clostridium isolate was the greatest in gentamicin (87%), then in order of amikacin (80%). There were 55.6% of Clostridium isolates showed multiple drug resistance (MDR). These results showed that a lot of Clostridial bacteria from wild animals in Seoul zoo were acquired antibiotic resistance. Because of the wild animal's aggressive manner, it has been hard to collect clinical samples from wild animals in a zoo to exam antibiotic susceptibility. For these reasons, empirical use of antibiotics has been performed in frequently. It may cause to increase the emergence of antibiotic resistance bacteria. In addition, the antibiotic resistance bacteria from zoo animals can be spread to other wild animals which inhabit around the zoo. Therefore, regular monitoring of antibiotic resistance Clostridial bacteria is important to protect animals and humans from Clostridial diseases.

  • 계획이 잘 된 이상적인 동물원이란 일차적으로 전시동물에 대한 생태학적 고려가 잘 된 것을 말하며 그 다음으로 관람자의 편의성과 즐거움을 위해 레저$.$휴식을 제공하는 동물원이라 할 수 있다. 하지만 이러한 양면의 목적을 제대로 현실화시킨 동물원을 찾아보기란 쉽지 않다. 동물원을 계획하고 설치할 때 모든 요소들을 거시적으로 통합하는 계획 능력의 부족으로 일어나는 디자인의 문제점 또한 거론하지 않을 수 없다. 이 는 깊이 있는 전문적 지식과 정보가 부재하여 각 부분들이 가지는 전체적 통일이나 다양한 내용이 상호 커뮤니케이션화 되어 있지 않고 있기 때문으로 풀이할 수 있다. 그러므로 놀이와 학습과 관람 및 레저의 목적을 겸한 동물원에 대한 통합디자인은 아무리 강조하여도 지나치지 않다. 동물원에는 아이덴티티 프로그램(identity program), 퍼니처시스템(furniture system), 동물의 쇼룸, 우리와 부대시설 등의 요소들이 상호 조화하는 종합된 디자인 사고가 요구된다. 본 연구는 이와 같은 개념에서 접근한 대구광역시 달성공원에 대한 통합디자인 연구라고 할 수 있다. 동물원을 겸하고 있는 달성공원의 이용형태를 시각환경과 생태환경이 서로 조화할 수 있도록 새롭게 분석 종합하여 바람직한 통합디자인이 될 수 있도록 연구해보았다.

  • The purpose of this study was to examine antibody titers to structural protein (SP) of the foot-and-mouth disease (FMD) virus after vaccination in animals of the Seoul zoo. After the initial inoculation of FMD vaccine to the susceptible animals of the zoo, a total of 235 blood samples were collected from 42 species of zoo animals during treatment or necropsy. All samples were tested by using enzyme-linked immunosorbent assay (ELISA). The overall positive rate of SP antibodies against FMD virus was 94.0% (221/235). However, the positive rates varied according to animal species. The results of positive rates in 30 species were 100% but in 12 species were 50-94.7%. We showed that most animals that have received FMD vaccine in Seoul zoo have been reached to the level of herd immunity against FMD virus after the vaccination. To the best of our knowledge, this study would be the first report for monitoring the vaccine-induced SP antibody titers against FMD virus after vaccination in various zoo animal species in Korea.
