Heat stress has adverse effects on the reproductive performances of dairy cattle and
buffaloes. The dairy sector is a more vulnerable to global warming and climate change. The …

Background Over several decades, a wide range of natural and artificial selection events in
response to subtropical environments, intensive pasture and intensive feedlot systems have …

Thailand is a tropical country affected by global climate change and has high temperatures
and humidity that cause heat stress in livestock. A temperature–humidity index (THI) is …

Selection for heat tolerant (HT) animals in dairy production has been so far linked to
estimation of declines in production using milk recording and meteorological information on …

The objective of this study was to evaluate the reproductive performance of the Holstein
(HO) and their backcross HO× Brown Swiss (BS) under Egyptian subtropical conditions. The …

Elucidating the physiological mechanisms that control reproduction is an obvious strategy
for improving the fertility of cattle and developing new agents to control reproductive …

Thermal stress due to extreme changes in the thermal environment is a critical issue in cattle
production. Many previous findings have shown a decrease in feed intake, milk yield, growth …

Selection has been emphasized for increasing production traits with ignoring the fertility
traits, which leads to a general loss of reproductive fitness. The aim of this study was to …

Heat stress strongly negatively affects reproductive traits in dairy cattle. The purpose of the
present study was to investigate the effect of heat stress in superstimulated Thai-Holstein …

The objectives of this study were to investigate genotype by environment interaction effects,
with environments defined as calving month and geographic location, on the interval from …
