Sri Lanka is an island in the tropics having a cattle population of about 1.7 million. In order to improve the productivity of these animals crossbreeding trials were initiated about 2-3 decades ago.

The indigenous cows were bred to bulls of Jersey, Friesian and Shorthorn breeds. Improted Zebu breeds such as Sindhi and Tharpakar were also bred to bulls of temperate breeds.

The article describes the findings of these experiments and their usefulness in formulating breeding policies for the different agroclimatic zones of the country.
