Items	SID valine:lysine ratio (%)				SEM	p-value
	50	60	70	80		Treatment	Linear	Quadratic
Feed intake (g/d)	607	640	657	629	34.5	0.49	0.43	0.20
Weight gain (g/d)	383	412	426	397	17.9	0.07	0.27	0.02
Feed efficiency	0.64	0.65	0.65	0.64	0.03	0.98	0.87	0.72
Daily SID valine intake (g/d)	4.07	5.06	5.99	6.48	0.27	<0.01	<0.01	0.23

SEM, standard error of the mean. N = 6.
