Despite many challenges faced by animal producers, including environmental problems,
diseases, economic pressure, and feed availability, it is still predicted that animal production …

Life-history trade-offs between components of fitness arise because reproduction entails
both gains and costs. Costs of reproduction can be divided into ecological and physiological …

The role of energy in ecological processes has hitherto been considered primarily from the
standpoint that energy supply is limited. That is, traditional resource‐based ecological and …

Heat stress reduces cow milk yield and results in a significant economic loss for the dairy
industry. During lactation, heat stress lowers milk production by 25 to 40% with half of the …

Selection for hyper‐prolific sows has increased the litter size by more than 50% during the
last three decades, and proper nutrition of the female pigs has concomitantly changed due …

There is a comprehensive body of literature on how increased air temperature affects the
physiology, production and behaviour of sows, while very few studies consider the thermal …

The aim of the experiment was to study the impact of high ambient temperature (25° C)
around farrowing on crated sows unable to perform thermoregulatory behavior. Twenty sows …

Several lines of evidence indicate that animals in the wild may be limited in their maximal
rates of energy intake by their intrinsic physiology rather than food availability …

Heat stress (HS) induces adaptive responses that are responsible for alterations of
carbohydrate and lipid metabolism. This study aimed to evaluate the effects of chronic heat …

Inadequate dry matter intake only partially accounts for the decrease in milk protein
synthesis during heat stress (HS) in dairy cows. Our hypothesis is that reduced milk protein …
