Abstract:
The present investigation was planned to evaluate the usefulness of Infrared thermorgraphical camera for discrimination of various stages of estrus i.e. onset of estrus, standing heat and non estrus conditions in sahiwal cows. The experiments were conducted on ten healthy, cyclic sahiwal cows were maintained at DDD farm of LFC at DUVASU, Mathura. In present study the mean infrared thermographical temperature of muzzle and vulva of sahiwal cows during standing heat stage (34.72±0.21 and 39.15±0.15ºC, respectively) were found to be significantly (p<0.01) high as compared to two other stages of estrus. Thus, from present study it was concluded that infrared thermoradiography may be used as the efficient tool for detection of estrus and its different stages in sahiwal cows.
