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

During their separate evolution from Bos taurus, zebu cattle (Bos indicus) have acquired
genes that confer thermotolerance at the physiological and cellular levels. Cattle from zebu …

Heat stress causes a large decline in pregnancy success per insemination during warm
times of the year. Improvements in fertility are possible by exploiting knowledge about how …

Environmental heat stress, present during warm seasons and warm episodes, severely
impairs dairy cattle performance, particularly in warmer climates. It is widely viewed that …

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 …

Abstract In the Northern Hemisphere, from June to September and in the Southern
Hemisphere from December to March, there are periods of reduced fertility (sub-fertility) in …

In cattle, genetic variation exists in regulation of body temperature and stabilization of
cellular function during heat stress. There are opportunities to reduce the impact of heat …

The objective was to determine whether exposure of Gir (Bos indicus) cows to heat-stress
(HS) causes immediate and delayed deleterious effect on follicular dynamics, hormonal …

This study was undertaken to assess whether peripheral blood mononuclear cells (PBMC)
isolated from Brown Swiss (Br) and Holstein (Ho) cows and stimulated with concanavalin A …

Heat shock proteins (Hsp) are known to protect cells from several stressors. Nucleotide
changes in the flanking regions [5′-and 3′-untranslated region (UTR)] of Hsp gene might …
