Busaca
Busaca (8 March 1974 – after 1983) was a French-bred, British-trained Thoroughbred racehorse and broodmare. Racing only as a three-year-old she won five of her eight races and was rated one of the best British fillies of her generation over middle and long distances. After winning three minor races in spring she finished second in the Ribblesdale Stakes and then recorded her first major win when taking the Lancashire Oaks at Haydock Park in July. In the following month she moved up to the highest class to win the Yorkshire Oaks over a field which included the Epsom Oaks winner Dunfermline. She was retired from racing after finishing fourth in the Prix Vermeille but had no success as a broodmare.
