A reappraisal of amino acids in broiler chicken nutrition

Growth performance of male broiler chickens in different growth phases in response to amino acid concentrations in the pre-starter diet

“…This may help reduce the impact of different dietary protein levels and diminish the potential limitations in protein accretion caused by varying ideal protein ratios. The differences in digestion and absorption between protein-bound and non-bound AA are well documented by the previous literatures [27,28], however, in this study, the protein accretion might be explained by increased AA concentrations derived from non-bound AA. The average standardized ileal AA digestibility of protein-bound AA, specifically corn and SBM used in this study, was determined to be 87.1% and 88.7%, respectively, based on data from three previous studies [29][30][31].…”

Standardized ileal digestible methionine requirements for 22 to 29-d-old male broilers based on the growth performance and feather development

“…In addition, the AA composition in feathers in the present study was similar to the previous studies [ 37 - 39 ]. In this context, birds may be more sensitive to dietary AA depend on the contribution on feather synthesis compared to the dietary Met, given its relatively higher proportion (7.33%) deposited in feather compared to Met (0.57%) [ 40 ].…”

Assessment of the amino and fatty acid composition and biological value of meat of broiler chickens taken by “Subtiform” probiotic bio preparation

“…When feeding poultry, rations should be used, which contain a sufficient amount of crude protein, which will ensure the improvement of the metabolism of the poultry and the saturation of the bird's body with amino acids, which take part in the formation of meat quality (Selle et al, 2023). Feeding poultry a diet that includes probiotics improves the quality of meat and eggs (Fluck et al, 2023).…”
