This study was carried out in thoroughbred colts grazed in pasture at summer season of Jeju island, Korea, from June 23 to 29 in 2007. We investigated the behavioral pattern of the thoroughbred colts (n=23) at the age of 3-year-old (n=11) and 1-year-old (n=12). The group behavioral pattern of thoroughbred colts was different according to the age. It was shown that eating 56%, standing 23%, lying 10%, walking 5%, running 2.5% and drinking 3% in the 1-year-old thoroughbred colts group. Especially, it was significantly individual difference (P less than 0.05) in the average behavioral expression ratio of 1-year-old thoroughbred colts (n=3), which was eating 53%, standing 29%, lying 11%, walking 5%, drinking 1% and running 1%. On the other hand, it was investigated that eating 54%, standing 27%, walking 13%, running and drinking 1.5%, lying 1% in the 3-year-old thoroughbred colts group. Also, the individual behavioral expression ratio of the 3-year-old thoroughbred colts was eating 53%, standing 32%, walking 10%, running and drinking 1%, which was a similar pattern to the result of 1-year-old colts. It is considered that this is the first study regarding a pasturage action of a racehorse produced in Korea. These data cannot be enough, but this data will be based on the production of racehorses and fostered in the management.
