English: Tuli bull - some are used as donor sires to broaden the gene pool in cattle breeding. The Boran and Tuli cattle breeds from Africa were introduced into the Australian cattle industry in the mid-1990s to produce crossbreeds that would benefit from the early maturing characteristics of the Afriacan breeds, providing an option for producers to boost both the meat quality attributes and the fertility of existing genotypes. In a large scale commercial trial, the Boran and Tuli crossbreds grew as well on grass as did other breeds, but in the feedlot they had advantages, particularly in their meat quality characteristics. Boran and Tuli crossbreds had higher than average eye-muscle areas and a higher proportion than other crosses had better than average marbling.
