Crossbreeding has been taken as a major tool for improving the animal productivity in different Asian countries. Bos taurus cattle have been used as exotic breeds and mated with local Bos indicus cows to introduce genes for higher productivity, resulting in much faster advances in productivity than could be obtained through selective pure breeding of local animals. The crossbreeding also brings in added advantages of heterosis. In dairy cattle, Holstein-Friesian is most commonly used and seems to nick well with most of the Bos indicus breeds.
