What is "lochnager"

Lochnager (4 March 1972 – 1994) was a British Thoroughbred racehorse and sire. A specialist sprinter, he raced mainly in the North of England winning nine of his sixteen starts and was regarded as the best horse in Europe over sprint distances in 1976. He won one minor race as a two-year-old but made relentless progress when campaigned in handicap races in 1975, winning several valuable events. He emerged as a top-class performer as a four-year-old, establishing himself as the year's best sprinter with a run of four successive wins in the Temple Stakes, King's Stand Stakes, July Cup and William Hill Sprint Championship. He made little impact at stud, but was the damsire of Lochsong.
