  • In ancient times, horse racing was done in ancient European countries in the form of wagon races or mountain races, and wagon racing was adopted as a regular event at the Greek Olympic Games. Thoroughbred horse has been bred since 17th century by intensive selective breeding for its speed, stamina, and racing ability. Then, in the 18th century, horse racing using the Thoroughbred species began to gain popularity among nobles. Since then, horse racing has developed into various forms in various countries and have developed into flat racing, steeplechasing, and harness racing. Thoroughbred racehorse has excellent racing abilities because of powerful selection breeding strategy for 300 years. It is necessary to maintain and maximize horses' ability to race, because horse industries produce enormous economic benefits through breeding, training, and horse racing. Next-generation sequencing (NGS) methods which process large amounts of genomic data have been developed recently. Based on the remarkable development of these genomic analytical techniques, it is now possible to easily carry out animal breeding strategies with superior traits. In order to select breeding racehorse with superior racing traits, the latest genomic analysis techniques have to be introduced. In this paper, we will review the current efforts to improve race performance for racehorses and to examine the research trends of genomic analysis. Finally, we suggest to utilize genomic analysis in Thoroughbred racehorse and Jeju horse, and propose a strategy for selective breeding for Jeju horse, which contributes job creation of Korea.

  • This study was conducted to provide basic information for the improvement of racing performance of Jeju pony & Halla horse, using the 85,732 racing records collected from Jeju & Kwacheon racecourses from January 1, 2005 to December 31, 2009. During the last 5 years, a total of 2,892 heads of horses were racing at the Jeju racecourse and 11.7% (338 heads) of them were Jeju ponies. The average body weight of Jeju pony and Halla horse were 267 kg & 287 kg, respectively, which were 58% and 62% of that of Thoroughbred (460 kg). The repeatabilities of Jeju pony, Halla horse and Thoroughbred for finishing time were estimated in the range of 0.26-0.66 (average, 0.54), 0.34-0.68 (average, 0.56) and 0.37-0.60 (average, 0.50), respectively, and as the racing distance increased, the repeatabilities decreased. In the racing distance of 1,000 m, the differences in the finishing times between Thoroughbred & Jeju pony, Thoroughbred & Halla horse, and Jeju pony & Halla horse were 24.33 seconds, 10.81 seconds and 13.52 seconds, respectively. The racing performance of Halla horse was improved by 55.6% than that of Jeju pony at the 1,000 m race.

  • Gyeongju, with its thousand-year-old history of the Silla Dynasty, is an impressive historical city where beautiful nature of mountains in the background and rivers in its front is getting along with the city landscape. The historic landscape of Gyeongju is divided into three groups: the old town, the ruins preservation region in the southeast of old towns, and the natural landscape region surrounding these regions. The old town region shows a common landscape of which general small cities in Korea may have, while its surroundings display the overlaps of natural and historic landscapes. The special city landscape is presented only in Gyeongju. Nevertheless, the northern area of the old town was built based on the concept of new towns without any height restriction of buildings, damaging the historic landscape of Gyeongju. It is misjudgment by interpreting the cultural heritage as the individual artifact rather than the continuous historic landscape. Since the 1970s when rapid industrialization and urbanization appeared along with the comprehensive development for Gyeongju tourism, the historic landscape has been slowly damaged. There were not enough financial and political supports from the central government, because the project for Gyeongju tourism was focused on the investment on the tourist industry. Now, in order to preserve the historical city like Gyeongju which represents the culture of Korea, the central government should actively engage in its protection. Policies of the central government should be focused on educating people that the historical restoration of Gyeongju is a way of recovering the national pride, and drawing the agreement of people. For its accomplishment, the government should change its policy from economy-oriented to culture-oriented. That is, the cultural policy should be emphasized.

  • The objective of this study was to estimate genetic trend on racing time of Thoroughbred racehorses in Korea, using a total of 209,725 racing records of 9,934 racehorses collection from January, 1990 to December, 2006. Phenotypic trends for all distances were negative at a rate of -0.148, -0.137, -0.137 and -0.139 second per race year for distances of 1,000m, 1,400m less than, 1,700m more than and overall dataset, respectively. Environmental trends were similar to phenotypic ones in all distances and trends in permanent environmental and jockey effects by race year were not found. Average genetic improvements for racing time were -0.037 and -0.030 second per race year at the 1,000m and overall dataset, respectively, which is low. But Genetic trends were decreased consistently. There is need to establish the genetic improvement program for quality of racehorses.
