Effect of heat stress on pregnancy rates of crossbred dairy cattle in Terai region of Uttarakhand, India

Conclusions These results indicate that reduction in pregnancy rates of crossbred dairy cattle due to heat stress in the Terai region was evident only when both growth of the ovulatory follicle and fertilization and early embryonic development occurred in the heat stress period. In addition, the study showed that use of temperature humidity indices rather than the traditional seasonal classification could provide more accurate insights into the effects of heat stress on pregnancy rates of crossbred dairy cattle in the Terai region.
