The replacement rate in cattle breeding has an important effect on the profitability of breeding as well as the success of the breeding program. Removal decision from herd will play an important role whether the replacement rate high or low. The reasons for culling were reported as low milk yield (29-36%), reproductive problem (15-27%), mastitis (18-23%) and other causes (25%).
