Crossbreeding with improved Bos taurus breeds in India is not new. It has gone on for nearly one century. CAR sanctioned a large crossbreeding scheme in 1955 for hilly and heavy rainfall areas for determining the optimum proportion of exotic inheritance in crossbreds which could sustain productivity after interbreeding under village conditions. The exotic breed used was Jersey. A number of bilateral aided projects like Indo-Swiss Project in Kerala and Punjab using Brown Swiss bulls on local cows, Indo-Danish Project in Karnataka using Red Dane bulls on Red Sindhi cows and Indo- German project in Himachal Pradesh for performance recoding under field conditions were also initiated during sixties and seventies. Based on the initial results of these bilateral projects, the work on performance recording of crossbreds under field conditions was initiated by the National Dairy Development Board under Operation Flood and a number of other organizations like BAIF.
