Livestock production both contributes to and is affected by climate change. In addition to the
physiological effects of higher temperatures on individual animals, the consequences of …

It is well documented that global warming is unequivocal. Dairy production systems are
considered as important sources of greenhouse gas emissions; however, little is known …

The data set for this study comprised 1,488,474 test-day records for milk, fat, and protein
yields and fat and protein percentages from 191,012 first-, second-, and third-parity Holstein …

The objectives of this retrospective study were to (1) investigate the effects of heat stress
(HS) climatic conditions and breed on milk and component yield for Holstein and Jersey …

The objective of this study was to compare the effect of the temperature-humidity index (THI)
on milk production traits and somatic cell score (SCS) of dairy cows raised in 4 different …

Genetic parameters that considered tolerance for heat stress were estimated for production,
udder health, and milk composition traits. Data included 202,733 test-day records for milk …

Genetic selection has been a very successful tool for the long-term improvement of livestock
populations, and the rapid adoption of genomic selection over the last decade has doubled …

This study evaluates the effect of heat stress on milk production and describes the pattern of
response of milk yield to increasing heat load, using temperature-humidity index (THI) on …

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 …
