Exploitation of genetic and physiological determinants of embryonic resistance to elevated temperature to improve embryonic survival in dairy cattle during heat stress.

Abstract excerpt

Heat stress causes large reductions in fertility in lactating dairy cows. The magnitude and geographical extent of this problem is increasing because improvements in milk yield have made it more difficult for cows to regulate body temperature during warm weather. There have been efforts to improve fertility during heat stress by exploiting determinants of oocyte and embryonic responses to elevated temperature....
