Postpartum Reproductive Performance Of Kedah Kelantan Cattle And Its Crossbreds

The calving interval of 286 Kedah-Kelantan (KK) cattle and KK crossbreds were obtained from the individual cow breeding records from a crossbreeding project between 1988 to 1990 at Livestock Research Centre MARDI, Kluang, Johore. Postpartum ovarian activity and fertility in 80 suckled cows were...
