Effects of crude protein (CP) proportion in diets on growth performance in weaned piglets.

Item	Diets1		SEM	P-value
	CP17	CP20
Initial BW, kg	9.56	9.48	0.142	0.972
ADG, g	446.6	505.4	18.5	0.003
ADFI, g	766.8	837.6	27.6	0.089
F:G ratio	1.71	1.65	0.0290	0.793
Final BW, kg	29.64	32.23	0.799	0.039

BW = body weight; ADG = average daily gain; ADFI = average daily feed intake; F:G ratio = feed to gain ratio.

¹CP20 is the diet containing 20% CP; CP17 is the diet containing 17% CP. Number of observation is 6.
