Abstract:
Estrus identification in dairy animals is always a point of interest as it is well established that the pregnancy rate associated with heat detection rate; therefore in the present study 80 multiparous and 24 cyclic heifers of Sahiwal cows were monitored by digital thermal imaging DarviDTL007 camera during estrus and non-estrus period. The vulval, eyeball, ear and muzzle images of 12 cyclic heifers and 40 cyclic multiparous Sahiwal cows in estrus and a similar number of animals in the non-estrus period were taken. The images were analyzed by Darvi T1 analysis software. The results depicted that the muzzle (2.4 °C and 1.37 °C), eye (0.64 °C and 1.6 °C), ear (1.2 °C and 1.5 °C), and vulva (1.95 °C and 2.41 °C) temperature was found to be significantly (p<0.05) higher during estrus period as compared to non-estrus period both in cyclic multiparous and cyclic heifers of Sahiwal cows. Therefore, IRT is an upcoming non-invasive technology that can be used to monitor increases in temperature of Sahiwal cows during estrus.
