An evaluation of the role of exotic or introduced breeds, including both B. taurus and B. indicus, in dairy and beef breeding improvement in tropical Asia, mainly South Asia and Southeast Asia, is the major aim of this paper. For dairy production the Holstein-Friesian (HF) is one of exotic breeds which appeared to make very significant impact through crossbreeding. It is anticipated that crossbreds with high percentages of HF or even purebred HF will soon become useful and profitable for smallholder dairy farmers in Asia. Some new dairy breeds introduced by some countries in Asia were not very different in milk yield from locally produced crossbreds of similar genotypes. As for beef breeding the Brahman (BR) cattle appeared to make the most significant impact at small farm level through crossbreeding with local indigenous cattle as well as through purebreeding. During the recent years B. taurus genotypes such as Charolais, Hereford, and Shorthorn had been introduced to improve the growth rate and carcass qualities of the crossbreds. The future use of some new beef breeds such as Santa Gertrudis, Droughtmaster, or Charbray was very much uncertain due to their unclear genetic advantages.
