Heat Detection Techniques in Cattle and Buffalo

Proper heat detection for achieve appropriate timing of insemination is the major limitation in achieving high conception rate in dairy herd. Failure to detect estrus leads to delayed insemination, longer calving intervals, higher culling rates, considerable economic losses and overall reduces in the fertility status of herd. Among all behavioural signs, standing to be mounted is considered the most reliable indicator for estrus and the timing of ovulation can be accurately predicted based on the period of standing heat. Feeding practices and overall management conditions play a particularly important role in estrus behaviour of animals. for enhance the efficiency of heat detection in animals, visual observation is one of the most effective methods and three times daily for a minimum duration of 30 minutes during each observation period. Timing of ovulation is a critical factor in dairy reproduction management for success of artificial insemination depends on inseminating the animal at the right time. Research has shown that accurately detecting estrus plays a major role in maintaining the herd’s reproductive performance. Therefore, careful and routine observation of the dairy herd is essential to minimize unobserved estrus.
