Little research has been done on investigating the specific characteristics of Jeju Ponies (Korean native horse) and Jeju Pony crossbreds. The authors performed evaluation of skin thickness of the skin of these breeds (n=205) at Jeju Race Park as a way of find of hippological difference. Results of this study showed that the Jeju Pony's skin were thicker than the Jeju Pony crossbred. The male's skin were thicker than the female's skin in two breeds respectively. Especially, in the Jeju Pony show significant differences (P < 0.05). In Jeju Pony crossbreds, as the skin thickness were thinner with age increase. 2-year-old group's skin significantly thinner than 3 and over 4-year-old groups. However, the Jeju Pony's skin were not significantly different by age. In conclusion, the authors thought that causes of the difference of the breeds were origin and genetic differences among the horse and the pony. Furthermore, the modified umbilical herniorrhaphy with rubber rings must be used cautiously in the Jeju Pony. It should be taken into account the animals' skin thickness when the leather goods created by using their skin.

The purpose of this study was to evaluate hippological differences between Jeju ponies and Jeju Pony crossbreds population. This is the first repot of the differences use an anhidrosis in Korean native horses. The precise prevalence of anhidrosis is unknown; however, it has been estimated that 6-20% of horses may be affected. However, there is no report about the incidence of the disease in pony breeds. We performed diagnosis by clinical signs (sweating) to investigate the incidence of anhidrosis in Jeju Ponies(n=340) and Jeju Pony crossbreds (n=536) at Jeju Race Park from July to September in 2012 as a way of find of hippological difference. Results of this study showed that 74 (21.8%) of the 340 examined Jeju Ponies and 61 (11.4%) of the 536 examined Jeju Pony crossbreds had anhidrosis. So, the former had almost two times higher than the later. Among 74 Jeju Ponies those had the disease, 50 were male (23.1%) and 24 were female (19.4%). Among 61 Jeju Pony crossbreds those had the disease, 22 were male (9.5%) and 39 were female (12.8). In Jeju Ponies, anhidrosis were most common in above the age of 5, followed by 4, 2, 3-years-old. For Jeju Pony crossbreds, the disease were most common in 2-years-old, followed by above the age of 5, 4, 3-years-old. In two breeds, 3-year-old animals were most rare respectively. There was no predilection of age and sex which is correlated with another study. In conclusion, the incidence of anhidrosis in the ponies were considerably similar foreign countries. However, the authors thought that causes of the difference of the breeds were origin and genetic differences.

The object of this study was to evaluate the possibility and incidence of innate pacer in Jeju raceresource. This peculiar gait occurs naturally in some foreign breeds. To author's knowledge, this is the first report of innate pacers on the Korean native horse. In order to determine the incidence of pacer in Jeju Ponies and Jeju Pony crossbreds, gait analysis and pedigree check were performed at the Let's Run Park Jeju (total 547 ponies and pony crossbred racers) in 2013. Results of this study showed that 16 (8.1%) of the 198 examined Jeju Ponies. However, 349 Jeju Pony crossbreds had no innate pacers. Of the 16 Jeju Pony pacers, 11 males (68.8%) and 5 females (31.2%) are included in the present study. In conclusion, only the Jeju Pony was innate pacers like other foreign breeds. The authors suspect that the causes of the difference of the breeds were origin of the pony and genetic differences.
