This study aimed to detect the effect of rice straw burning emissions on some metabolic and hormonal parameters as well as its effect on some reproductive indices in local crossbred cows under field condition in Egypt. About 203 local cross-breed cows-reared at villages of Al-Sharkia governorate, Egypt -were divided into two main groups, control group included 90 cows reared in areas free from rice straw burning and second group were exposed to rice straw combustion products during the period

While, estradiol-17 level, total lipids and triglycerides values were not significantly affected. Days open, number of services per conception and incidence of smooth inactive ovaries were higher in exposed than non-exposed cows. In conclusion, ovarian activity and reproductive efficiency in cows exposed to rice straw burning emissions were adversely affected.
