The reduction of productivity and efficiency of nutrient utilization in heat-stressed dairy cattle
is mediated by physiological and molecular alterations. Heat stress impairs the digestive …

A great diversity of species of microorganisms are present in the rumen environmental with
specific functions in the degradation of carbohydrates, protein and lipids. However, the …

This study aimed to verify the effects of heat stress and dietary energy level on dry matter
intake (DMI), water intake, total and partial ruminal and intestinal digestibilities, ruminal …

The objective of this study was to evaluate the effect of heat stress on meta-taxonomic and

Background In recent years, there has been an increasing interest in using high quantities of
milk or milk replacer (MR) in heat-stressed calves to alleviate the negative effects of high …

We aimed to study how seasonal heat stress (ie, spring vs. summer) influenced microbiota
diversity in the dairy cows' feces using Illumina MiSeq sequencing. Sixteen dairy cows were …

Heat stress hinders growth and well-being in livestock, an effect that is perhaps exacerbated
by the β1 agonist ractopamine. Heat stress deficits are mediated in part by reduced feed …

This study aimed to investigate the effect of heat stress and month of birth on growth
performance, pelleted starter intake, and stress-related hormones in Holstein calves. Birth …

The study objective was to evaluate the effects of a phytogenic feed additive (PFA) on dry
matter intake (DMI), average daily gain (ADG), inflammation, and oxidative stress markers of …
