Apparent digestibility coefficients of branched-chain amino acids in four small intestinal segments and their digestion rate constants in birds offered sorghum-based diets (adapted from [44]).

Amino Acid	Apparent Digestibility Coefficient				Digestion Rate (× 10−2 Per Minute)
	Proximal Jejunum	Distal Jejunum	Proximal Ileum	Distal Ileum
Isoleucine	0.363	0.568	0.726	0.774	2.05
Leucine	0.359	0.536	0.695	0.748	2.07
Valine	0.352	0.560	0.715	0.760	2.04
