Genetic selection for high growth rate has resulted in spectacular progress in feed efficiency
in chickens. As feed intake and water consumption (WC) are associated and both are …

With climate change, selection for water efficiency and heat resilience are vitally important.
We undertook this study to determine the effect of chronic cyclic heat stress (HS) on the …

Genetic selection for high growth rate has resulted in tremendous changes not only in feed
efficiency, but also in water consumption between modern broilers and their ancestor jungle …

Heat stress (HS) has been increasingly jeopardizing the sustainability of the poultry
production. Moreover, modern high-performing chickens are far less able to withstand HS …

Heat stress (HS) is devastating to poultry production sustainability due its detrimental effects
on performance, welfare, meat quality, and profitability. One of the most known negative …

Heat stress (HS) has been reported to disrupt nutrient digestion and absorption in broilers.
These effects may be more prominent in fast-growing chickens due to their high metabolic …

Modern commercial broilers have been intensively selected for high growth rate, feed
efficiency and meat yield. This enhanced genetic selection, at the expense of the functional …

Background Low environmental temperatures are among the most challenging stressors in
poultry industries. Although landmark studies using acute severe cold exposure have been …

The hypothalamus plays an overarching role that is reflected in the physiological processes
observed in the entire organism. The hypothalamus regulates selected metabolic processes …

Background Tibetan chickens, a unique native breed in the Qinghai-Tibet Plateau of China,
possess a suite of adaptive features that enable them to tolerate the high-altitude hypoxic …
