Frequency of oestrus signs and pregnancy rates in oestrus synchronised Kedah-Kelantan crossbred cows offered two metabolizable energy levels

Synchronisation of oestrus in cattle can facilitate the use of artificial insemination by reducing the time needed for detection of oestrus compared to cows entering oestrus spontaneously. The purpose of the study was to determine the oestrous signs characteristics and pregnancy rates in Kedah-Kelan...
