Objective: The study investigated the origin of the Akhal-Teke horse using genome-wide single-nucleotide polymorphism (SNP) data and mitochondrial hypervariable region 1 (HVR-1) nucleotide sequences Methods: Genome-wide SNP data from 22 breeds (481 horses) and mitochondrial HVR-1 sequences from 24 breeds (544 sequences) worldwide to examine the origin of the Akhal-Teke horse. The data were analyzed using principal component analysis, linkage disequilibrium analysis, neighbor-joining dendrograms, and ancestry inference to determine the population relationships, ancestral source, genetic structure, and relationships with other varieties. Results: A close genetic relationship between the Akhal-Teke horse and horses from the Middle East was found. Analysis of mitochondrial HVR-1 sequences showed that there were no shared haplotypes between the Akhal-Teke and Tarpan horses, and the mitochondrial data indicated that the Akhal-Teke horse has not historically expanded its group. Ancestral inference suggested that Arabian and Caspian horses were the likely ancestors of the Akhal-Teke horse. Conclusion: The Akhal-Teke horse originated in the Middle East.

Lyme disease is a tick-borne zoonotic infectious disease caused by Borrelia burgdorferi. The present study assessed the infection status of B. burgdorferi among horses reared in Korea using ELISA and PCR. Between 2009 and 2013, blood samples were collected from 727 horses throughout Korea. Data for each animal including age, gender, breed, and region of sample collection were used for epidemiological analysis. Overall, 38 (5.2%; true prevalence: 5.5%) of 727 horses were seropositive by ELISA. There were statistically significant differences according to breed and region (P<0.001) whose differences might be attributed to the ecology of vector ticks and climate conditions. Using 2 nested PCR, none of the samples tested positive for B. burgdorferi. Thus, a positive ELISA result can indicate only that the tested horse was previously exposed to B. burgdorferi, with no certainty over the time of exposure. Since global warming is likely to increase the abundance of ticks in Korea, continuous monitoring of tick-borne diseases in Korean horses is needed.

말의 근골격계 질환의 진단과 치유 경과 평가를 위한 체열촬영술의 유용성을 검토코자 실험적으로 유발한 감염성 관절염의 치료 과정을 조사하였다. 실험적으로 완관절에 감염성 관절염을 유발하여 항생제와 봉독으로 처치한 후, 치료 과정별로 임상검사, 실험실 검사, 방사선 검사와 병행하여 실시한 체열촬영술은 전반적으로 모든 진단 결과와 유사하게 나타났으며, 진단 시 조직에 대한 비접촉성, 비침습성 및 무통성 특성과 함께 치유경과를 시각화, 객관화하므로 효과적인 것으로 판단되었다. 따라서 말의 근골격계 질환의 체열학적 평가는 기존의 검사나 진단 영상 장치와 더불어 말의 근골격계 질환의 진단 및 치유경과 평가에 있어서 유용할 것으로 사료된다.

In the Iranian epic $K{\bar{u}}shn{\bar{a}}ma$, there is a rather interesting story that recounts how the inhabitants of $B.s{\bar{i}}l\bar{a}$ cross-breed their domesticated horses with a magical horse living in the sea in order to obtain fine-bred ones. What is even more interesting is that similar accounts are also seen in many of other classical Perso-Arabic works and Chinese sources. The regions that such events took place in mainly spread over Central Asia and western China while in $K{\bar{u}}shn{\bar{a}}ma$, the story happens in $B.s{\bar{i}}l\bar{a}$, a legendary kingdom with its historical prototype being Silla. By sorting out certain records of how ancient people sought fine horses by cross-breeding domesticated horses with wild horses that inhabited mountains and waters within Chinese sources and classical Muslim works, and comparing these accounts with similar plot lines as depicted in $K{\bar{u}}shn{\bar{a}}ma$, this paper attempts to elucidate that the story in $K{\bar{u}}shn{\bar{a}}ma$ is a result of flourishing land and maritime exchanges between East Asia and West Asia during ancient and medieval times, rather than a purely literary fiction. It was not only influenced by the horse culture that thrived over the Eurasian Steppe, but the story is also coincidentally in accordance with the fact that the nomadic zone which lies within the central Eurasian continent extends as far as the Korean Peninsula in northeast Asia.

이 연구는 최초의 국내 말에서 수동면역부전을 다룬 것이다. 이 연구의 목적은 건강한 말과 아픈 말의 면역상태를 비교하는 것이다. 수동면역부전은 말에서 가장 흔한 면역결핍질환이다. 아픈말 22 마리와 건강한 말 18 마리를 검사키트(SNAP Foal IgG Test Kit)를 이용하여 수동면역부전을 진단하였다. 모든 성마는 정상적인 면역기능을 가지고 있었다(≥800 mg/㎗). 신생망아지는 22 마리 중 13 마리(59%; ∠800 mg/㎗)가 면역기능이 취약하였지만 치료 후 회복하여 생존하였다. 이 22 마리 중 9 마리는 면역기능이 강한 말(≥ 800 mg/㎗)로 혈중 IgG농도가 높아도 감염성 질환이 발생할 수 있다는 것을 보여준다. 폐사망아지는 모두 6 마리였고, 그중 4 마리는 감염성 질환이었다. 신생망아지 면역상태 검사를 통한 감염취약 정도의 조기진단 및 대응방안 마련으로 경주자원 활용율 제고와 보건관리 기술향상을 도모할 수 있다. 또한, 신생망아지의 감염성질환 조기 파악으로 향후 육성마의 체계적인 보건관리방안 마련에 일조할 수 있을 것으로 기대된다.

Background: Gastric ulcer is one of the prevalent diseases in racehorses. However, it has not been recognized as important in Korea, and drugs used to treat gastric ulcers are included in the doping test list, so they are not allowed to be administered to racehorses in training. Objectives: This study was performed 1) to investigate the prevalence and the severity of gastric ulcers in Thoroughbred racehorses in Korea, 2) to confirm the therapeutic effect of ranitidine and omeprazole, and 3) to compare the efficacy between ranitidine and omeprazole. Methods: Forty-nine horses were randomly recruited, and gastroscopy was performed within two days after racing. Twelve horses with a sum grade of five or higher were randomly assigned to two treatment groups. Seven horses were administered ranitidine, and five horses were administered omeprazole. Follow-up gastroscopy was scheduled within one to five days after finishing the treatment. Results: The prevalence of gastric ulcer in Korean Thoroughbred racehorses after racing was 100%, and the grade was more severe in the non-glandular region than in the pyloric region. There was no correlation between the severity of gastric ulcer in the two regions. Omeprazole had a greater therapeutic effect than ranitidine. Conclusions: This study shows the importance of recognizing gastric ulcers as an important factor, and omeprazole as a possible treatment option in Korea, as it has been removed from the list of prohibited substances for racehorses. Thus, the use of omeprazole is currently recommended until one day before the race.

The aim of this study was to investigate the usefulness and effectiveness of thermography in horse. Total 21 horses associated with locomotors, wound, and ophthalmic disease were investigated. Thermographically, the wannest area in normal limb was coronary band ($27.26^{\circ}C$), and carpus, metacarpus, fetlock, and pastern area were $26.64^{\circ}C$, $24.42^{\circ}C$, $23.64^{\circ}C$ and $23.06^{\circ}C$, respectively. The temperature($^{\circ}C$) of horses with lameness, swelling, nervous, ataxia was lower(cold spot) than surrounding tissue or symmetry area, and with heat, signs of inflammation was increased(hot spot). These results suggest that the thermography is useful for the early detection of locomotors, wound, and ophthalmic disease in horse and an excellent adjunct to clinical examination.

This study was conducted on 85 non-racing pleasure horses raised in Busan race park of Korea Racing Authority to investigate the prevalence of stereotypic behavioral problems in horses. the observation had been continued from March to October of 2010, and the study animals included warm-bloods, Jeju ponies and donkeys. Although there was no temperament problem detected, a wide range of well-known stable vices were observed in 15 horses. The most frequently observed stereotype was cribbing (8.2%), and it was followed by weaving (1.2%), biting (1.2%), eating too fast (1.2%), pawing (1.2%) and scraping the teeth on something (1.2%) with the equal prevalence rate. These behavioral disorders were only detected in warm-bloods, while those were absent in Jeju ponies and donkeys. In addition, primary behavioral disorders were more dominant than mimicking behaviors.

This research was conducted to investigate the effects of race conditions on racing injury in Thoroughbred(TB) horses. A total 335 horses were investigated the relationship between race conditions and racing injuries. The main environmental factors of racing injuries were spring season, rainy weather and sloppy racetrack. In the race types, high incidence of racing injury was found in special weigh, stakes, middle class and long length race. This results suggest that the racing injury can be effected to both individual body condition and various racetrack conditions.

Two cases of guttural pouch mycosis in race horses were observed for clinical and pathological aspects of the disease to investigate etiology and pathogenesis of dysphagia and epistaxis of the horse. In case 1 showing prolonged dysphagic sign a diphtheritic membrane was confined to the guttural pouch involved with neuritis of the glossopharyngeal nerve due to fungal penetration. The other horse showing fatal recurrent epistaxis had lesion of mycetoma invading the internal carotid artery to provoke erosion of the artery. An Aspergillosis sp. was isolated from the guttural pouches of the two horses and identified as A nidulans.
