Table 1. Effects of guanidinoacetic acid (GAA) supplementation on growth performance of broiler chickens from 1 to 42 days of age.

Variable	Control	GAA (0.5 g/kg)	GAA (1 g/kg)	GAA (1.5 g/kg)	GAA (2 g/kg)	LSD
Body weight gain	2101^b	2223^ab	2185^ab	2216^ab	2268^a	138.4
Feed intake	3912	4008	3918	3987	4027	111.7
Feed conversion ratio	1.91^a	1.87^ab	1.77^b	1.76^b	1.84^ab	0.118

Means in the same row with different letters are significantly different (P<0.05). The unit for body weight gain and feed intake values is grams per bird. Number of replicates=4.
