Simple Summary Holstein is the most popular dairy cattle breed worldwide due to its milk
yield. When these cows are exposed to heat stress, they reduce feed intake and milk …

Heat stress represents a major environmental factor that negatively affects the health and
performance of dairy cows, causing huge economic losses to the dairy industry. Identifying …

Dairy cows with increased rectal temperature experience lower milk yield and fertility. Rectal
temperature during heat stress is heritable, so genetic selection for body temperature …

Exposure of livestock to high heat loads negatively affects animal's productivity. Genetic
selection for heat tolerance using quantitative approaches has been developed by making …

Heat stress affects the physiology and production performance of Chinese Holstein dairy
cows. As such, the selection of heat tolerance in cows and elucidating its underlying …

Dairy products are a key source of valuable proteins and fats for many millions of people
worldwide. Dairy cattle are highly susceptible to heat-stress induced decline in milk …

Heat stress compromises production, fertility, and health of dairy cattle. One mitigation
strategy is to select individuals that are genetically resistant to heat stress. Most of the …

Dairy cattle are highly susceptible to heat stress. Heat stress causes a decline in milk yield,
reduced dry matter intake, reduced fertility rates, and alteration of physiological traits (eg …

Heat stress causes extensive losses in the dairy sector, due to negative effects on milk
production and reproduction. Cows have evolved a series of protective mechanisms …

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 …
