Equine colic is a major concern in equine industry due to high morbidity and mortality rates. The purpose of this study was to establish mortality rates during medically and surgically treated colic and to identify potential prognostic indicators for mortality of equine colic in Korea. The overall mortality rate was 18/119 (15%). The 93 cases (78%) were treated medically and 26 cases (22%) surgically out of the 119 records reviewed. The mortality rate in small intestinal lesion was 7/9 (78%) and strangulating lesion was 10/11 (91%). The significance between individual factors and prognosis of equine colic was not valid but high frequency rate was found in ${\leq}3$ years age (59%) and male (50%). In dead group showed higher, rectal temperature and heart rate than those of survived group. The mortality rate was significantly high in the pale mucous membrane color and severe pain and decreased intestinal motility. In laboratory factors, dead group showed lower level of platelet than survived group, and had higher values of RBC, hemoglobin, PCV with significance (P < 0.05). Group with increased enzyme activity of CK, LDH, glucose showed poor prognosis.

This study was conducted to investigate the effects of concentrate feeding frequency on weight change and the colic of Jeju cross-bred horses. Around thirty-six old Jeju cross-bred horses were divided into three groups and were investigated by feeding the concentrate feed at 2.5% of their body weight 2 times, 3 times, or 4 times daily. Although the total weight gain and daily weight gain for the different feeding frequencies were higher with feeding concentrates 4 times daily compared with the other treatment groups, there was no statistically significant difference between the groups (p>0.05). Rectal temperatures were above the normal range in weeks 11 to 12, but there was no statistically significant difference between the groups (p>0.05). Fecal pH was below the normal range in weeks 1 to 12, but there were no colic symptoms with any of the treatments and there was no statistically significant difference between the groups (p>0.05). When feeding concentrate feed at 2.5% of body weight, it was assumed that trying to feed it several times per day would help to prevent colic; however, there was no difference in weight gain, blood characteristics, and physiological characteristics in accordance with the number of feeding times.

After clinical and laboratory tests of a 12-year-old warmblood horse (castrated male, 540 kg) displaying symptom of pain, a diagnosis of intestinal obstruction due to foreign substances like sand was made and an abdominal section and enterotomy were conducted to confirm and extract the intestinal stone (enterolith) on the right dorsal part of the ascending colon. The extracted intestinal stone was around 2.9 kg and greenish brown rugby ball sized ($22cm{\times}10cm$) stone. Analysis of the element components (EDX) using a scanning electron microscope revealed percentages of C (30.08%), O (39.85%), Mg (3.89%), P (11.15%), and Ca (11.16%) at a magnification of 400. This was the first example of a successful extraction and treatment of intestinal stone in a horse domestically and thereby has its significance.

This experiment was conducted to investigate the effects of individual management and group management of Jeju cross-bred horses on the physiological characteristics, productivity, and characteristics of the loin muscle of the horse meat. Sixteen herds of Jeju cross-bred horses older than 44 months were selected as experimental subjects. The experiment was conducted by dividing the herds into eight herds for individual management and another eight herds for group management. Herds were fed with concentrated feed of 2.5% of the body weight for four times a day and roughage and water were fed ad libitum. In the 12th week, the intestinal pH was statistically significantly lower with group management than with individual management (p<0.05). However, no symptoms of colic were observed. With regard to the general composition of the loin muscle, fat content was a statistically significant difference between the 7.83% with individual management and 5.65% with group management (p<0.05), indicating that individual management is more effective than group management in terms of fattening. In conclusion, feeding a concentrated feed at a level of 2.5% of body weight with individual management during fattening of Jeju cross-bred horses could be utilized as a fattening method.
