RESUMO
Thoracic spinous process osseous changes in horses occur due to riding-induced back compression. This study aimed to evaluate the relationship between the findings of thoracic spinous process osseous changes on radiographic imaging and conformation based on the difference in over-riding of the dorsal spinous processes in racing horses. This study included 55 sports horses. The hardness of the back muscles (the multifidus, longissimi, and latissimi collectively) was measured, and the horses were divided into two groups: low muscle hardness (n = 16) and high muscle hardness (n = 39). We confirmed the effectiveness of a muscle hardness tester in measuring the hardness of the back muscles. It was revealed that horses with a long length from the saddle (13th thoracic vertebra) to the sacral lumbar joint (fifth lumbar vertebra) had higher muscle hardness. Additionally, horses with high muscle hardness demonstrated spinous process osteosclerosis.

Gastric ulcers cause appetite loss, poor body condition, and colic in horses. This study investigated the protective effect of a rice fermented extract on the gastric mucosa in 17 healthy Thoroughbreds. For one month, horses in the rice fermented extract (nine horses) and control (eight horses) groups were orally administered a rice fermented extract (100%; 0.2 ml/kg, SID) and tap water (0.2 ml/kg), respectively. Gastric endoscopic images were obtained before and one month after rice fermented extract administration. The gastric ulcer score was lower after administration (median, 1; maximum, 2; minimum, 1) than before administration (median, 4; maximum, 4; minimum, 3) in the rice fermented extract group (P<0.05). In conclusion, the administration of a rice fermented extract for one month improves gastric mucosal lesions in Thoroughbreds with gastric ulcers.
