A seven-month pregnant four-year-old Thoroughbred mare with colic weighing 600 kg was referred to the Jeju National University Equine Hospital. A physical examination and ultrasound suggested epiploic foramen entrapment. The patient underwent ileum resection and end-to-side jejunocecostomy. After surgery, the horse showed a consistent pain when introduced to feeding. A repeat laparotomy was performed to enlarge the stoma size with side-to-side jejunocecostomy. The repeat laparotomy was successful, and the mare gave birth uneventfully. This report describes a case of small intestinal epiploic foramen entrapment and the clinical outcomes of the 2 consecutive laparotomies a Thoroughbred mare in late gestation.

Two 4-day-old Thoroughbred foals with acute clinical signs of depression, elevated pulse and respiratory rates, anemia, and jaundice were referred to the equine hospital of Korea Racing Authority. The foals were seemingly normal at birth, but showed clinical signs such as abnormal behavior, jaundice and anemia suddenly after ingestion of the mare's colostrum, followed by death at 4 days after birth. According to the results of the hematology, serum chemistry analysis, jaundice foal agglutination test, and blood groups test, the foals were diagnosed as neonatal isoerythrolysis (NI) caused by the mare's antibodies. These results suggested that the pregnant mares have a potential for NI.

This research was conducted to investigate the group and individual behavioral patterns of thoroughbred mares which are important for raising race-horses, in paddoks (pregnant) and pastures (nursing). In a group of nursing mare, eating 62%, standing resting 31%, drinking 3%, lying resting 1%, walking 1% and nursing 2% were observed, although no running was observed. Average time spent on individual behavior of mares (3 heads) was eating 295 min (55%), standing resting 193 min (36%), walking 18 min, drinking 18 min (3%), nursing 13 min (2%), lying resting 6 min (1%). Average 11 times of grooming, 2 times of urinating, and 1 time of feces were observed for mare in pasture. 48% of standing resting, 44% of eating, 2% of lying resting, 4% of walking, and 2% of drinking were revealed for pregnant mares in paddock. Average individual behavioral pattern of pregnant mares (3 heads) was 52% of eating, 40% of standing, 6% of walking, and 2% of drinking. Average 15 times of grooming, 1 time of urinating, 3 times of feces, 1 time of fighting, and 2 times of rolling were observed for pregnant mares in paddock. For moving patterns, pregnant mares were inclined to concentrate on where the nearby paddok is close to.

Endometrial biopsy in the horse is an important technique for maintaining breeding soundness by detecting changes related with reduced fertility and monitoring response to specific uterine therapy. A 13-year-old thoroughbred mare had been in trouble with repeated breeding for getting pregnant before the sample of endometrial biopsy was offered to investigate the possibility of pregnancy in the future. Based on the tissue sections examined, the prognosis for this mare to conceive and successfully carry a foal to term was estimated to be 10 to 50%.

An 8-year-old Thoroughbred mare showing anestrus for longer than 6 months with left ovarian mass was referred to Veterinary Medical Teaching Hospital of Seoul National University. For 6 months, the mare had received 2 times hormonal therapies with $PGF_2{\alpha}$ and progesterone. The mare had not responded to these therapies and not shown estrous behavior. On rectal palpation, the left ovary was enlarged and contralateral ovary was small and inactive. Transrectal ultrasonographic examination of the left ovary revealed a mass composed of multiple, irregularly shaped follicles. Granulosa cell tumor (GCT) was suspected according to her history. Ovariectomy was performed through the left flank laparotomy with a standing position in a simple chute located outside of horse farm. The mass was diagnosed as GCT on histopathology. The mare was recovered without any problem and became pregnant next spring.

A 10-year-old Thoroughbred mare was referred to the Jeju National University Equine Hospital with roaring, dyspnea, and weight loss. On endoscopic examination, the horse was diagnosed with right arytenoid chondritis. Surgical treatment was selected due to the failure of a previous medical treatment. Permanent tracheostomy was performed in a standing position. The horse was restrained and tied in a proper position in the stock. The cranial parts of the 2nd to 5th tracheal cartilages were resected, as were the associated skin, mucosa, muscle, and cartilages. After the stoma was formed, external mucosa and skin were sutured using a simple interrupted method. The horse was hospitalized for 22 days receiving postoperative care including antibiotics, non-steroidal anti-inflammatory drugs, dressing as required, and was pregnant six months after the surgery. A permanent tracheostomy is thought to be effective in horses with diseases causing upper respiratory tract obstruction.

A seven-month pregnant 15-year-old Thoroughbred mare presented with acute abdominal pain to Jeju National University Equine Hospital. At presentation, a nasogastric intubation revealed 10 L of gastric reflux; rectal palpation and ultrasound revealed dilated loops and thickening of the walls of the small intestine. An exploratory laparotomy revealed strangulation of the small intestine due to a large abdominal mass. The mass was double-ligated and resected blindly due to the short pedicle. An enterectomy was not performed as intestinal motility was detected following the mass removal. Histopathological examination confirmed that the mass was a lipoma, measuring 24 cm × 16 cm × 16 cm in size. On day 8 post-surgery, the mare was discharged without complications. This case report describes the diagnosis and treatment of strangulation of the small intestine by a pedunculated lipoma, thus providing useful information on lipoma in horses.
