Heat stress is a widespread phenomenon in domestic animal feeding in tropical and sub-
tropical areas that are subjected to a growing negative effect in livestock and poultry due to …

Pig production faces seasonal fluctuations. The low farrowing rate of sows mated in summer,
increased carcass fatness of progeny born to the sows mated in summer, and slower growth …

Animals are biological transformers of dietary matter and energy to produce high-quality
foods and wools for human consumption and use. Mammals, birds, fish, and shrimp require …

Two experiments were conducted to determine the effects of feeding reduced-CP, AA-
supplemented diets at two ambient temperatures (Exp. 1) or three levels of dietary NE (Exp …

Reducing the dietary CP level with free AA supplementation allows reduction of N excretion
and the risk of gut disorders while maintaining performance of pigs. We have recently …

Heat stress (HS) has adverse effects on the body: it decreases body weight, feed efficiency,
feed intake, carcass quality, and nutrient digestibility. Chromium (Cr) can prevent lipid …

The effect of heat and humidity stresses on the rumen bacterial molecular diversity of heifers
was studied. No statistically significant changes in the rumen microbiota composition were …

The aim of this study was to investigate the effects of a long-term low protein diet on the
microbial composition and metabolomic profile in the hindgut of the pig. Thirty-six Duroc× …

Feeding pigs with very-low protein (VLP) diets while supplemented with limiting amino acids
(AA) results in decreased growth. The objective of this study was to determine if …

Maternal undernutrition or overnutrition during pregnancy alters organ structure, impairs
prenatal and neonatal growth and development, and reduces feed efficiency for lean tissue …
