Table 5. Weight gain, feed intake, gain to feed ratio, and feed conversion ratio of birds fed diets containing different concentrations of microalgae¹

Item	Dietary microalgae concentration (%)				SEM	P-value
	0	0.5	1.0	1.5		Linear	Quadratic
Weight gain (g/ for 7 d)	131	131	132	133	2.2	0.40	0.84
Feed intake (g/ for 7 d)	146	150	151	150	2.0	0.14	0.27
Gain to feed ratio (g/g)	0.90	0.88	0.88	0.89	0.017	0.75	0.33
Feed conversion ratio (g/g)	1.12	1.14	1.15	1.13	0.02	0.77	0.33

Each value represents mean of eight replicates per treatment.
