TL;DR: The supplementation of Val and Gly in low-CP diets was sufficient to avoid adverse effects in the performance and serum parameters of broilers in the starter phase, however, birds in the grower phase required the combined supplementation ofVal, Ile, Arg and Gly, to prevent compromised performance.

TL;DR: The supplementation of essential amino acids while maintaining dig Gly+Ser:Lys ratios at and above 137 allowed for a reduction in the dietary CP of 3% without undermining the performance, feathering or serum parameters of early stage broilers.

TL;DR: The consumption of diets contaminated with 1,500 &mgr;g AFB1/kg altered hepatic function in quail, impairing productive performance and egg weight and feed intake and the concentrations of silymarin and adsorbent evaluated were not able to mitigate the negative effect of toxins on the metabolism and performance of laying quail.

TL;DR: Dietary GAA supplementation of meat-type quail breeders increases the availability of creatine in eggs and muscle of progeny, which results in better reproductive parameters and better postnatal progeny performance.

TL;DR: It is necessary to consider the dietary Leu content to estimate the ideal level of Val in low‐CP diets for optimum broiler performance, as the supplementation of Leu and Val can reduce the abdominal fat deposition in birds fed low-CP diets during the grower phase.
