Heat stress can have large effects on most aspects of reproductive function in mammals.
These include disruptions in spermatogenesis and oocyte development, oocyte maturation …

Establishment and maintenance of pregnancy is difficult in lactating dairy cows exposed to
heat stress because of reductions in estrous detection rate and the proportion of …

Glutathione plays a critical role in many biological processes both directly as a co-factor in
enzymatic reactions and indirectly as the major thiol-disulfide redox buffer in mammalian …

The authors sought to determine whether developmental differences in the magnitude of
embryonic mortality caused by heat stress in vivo are caused by changes in resistance of …

Global warming represents a major stressful environmental condition that compromises the
reproductive efficiency of animals and humans via a rise of body temperature above its …

This paper examines the role that oxidative stress plays in small ruminant medicine. We will
examine how redox homeostasis is involved in some physiological functions and we will …

The production of embryos by superovulation is often reduced in periods of heat stress. The
associated reduction in the number of transferable embryos is due to reduced …

In three experiments, we tested the efficacy of timed artificial insemination (AI) and β-
carotene supplementation for improvement of reproduction and milk yield. Experiments 1 …

Apoptosis is a form of cell death that can function to eliminate cells damaged by
environmental stress. One stress that can compromise embryonic development is elevated …

Follicular growth, lifespan of the corpus luteum, and antioxidant status of lactating Holsteins
that experienced heat stress were monitored. Eleven multiparous cows, 60 to 110 d in milk …
