Table 1. Body weight gain, feed intake, and feed efficiency of chicks with a guide cannula in the third ventricle during 11 days after hatching.

	Intact (5)	Tribromoethanol (5)	Cannula (5)	P value
Body weight gain (P1–P5) (g)	18.96±1.52	17.9±1.73	15.84±1.67	0.421
Body weight gain (P6–P11) (g)	45.32±5.15	40.68±5.08	49.34±2.26	0.500
Feed intake (P6–P11) (g)	75.06±5.50	69.54±6.72	80.02±2.48	0.403
Feed efficiency (P6–P11)	0.60±0.03	0.59±0.03	0.62±0.01	0.727

The values represent the mean±SEM; n=5 chicks. P1–P5, 1 to 5 days after hatching; P6–P11, 6 to 11 days after hatching.
