TL;DR: Chronic heat stress impairs meat quality by causing mitochondria to malfunction and affecting energy-substance aerobic metabolism, resulting in increased glycolysis and intramuscular fat deposition.

TL;DR: Chronic heat exposure impairs the performance, intestinal morphology and appetite, which may be correlated with the increased secretion or gene expression of appetite-related hormones and genes, and the higher expression of nutrient-sensing receptors in broilers.

TL;DR: Results showed that oxidative stress induced by H2O2 had a negative effect on relative muscle weight, histomorphology, and redox status, while the underlying oxidative damage caused a decline in meat quality, which could be attributed to the apoptosis and autophagy processes triggered by excessive reactive oxygen species that suppress the NF-κB signaling pathway.

TL;DR: It is suggested that dietary addition of 2% L-glutamate improves the intestinal integrity and influences the expression of amino acid receptors and transporters in the jejunum of weaning, which is beneficial for the improvement of jejunal nutrients for digestion and absorption.

TL;DR: Dietary supplementation of marigold extract significantly increased the yellowness values of carcass, antioxidant capacity and meat quality in broiler chickens and no significant effect on growth performance was found.
