treatments had greater ADG than chickens in SC and
PC treatments from d 0 to 10 and from d 10 to 21. The
AOX and VE+AOX treatments had the best G:F from
d 0 to 10 and AOX alone had better G:F compared
with the HO, VE, SC, and PC treatments from d 22 to
42 and throughout the 42-d experimental period (P <
0.001). The VE treatment birds fell behind other treatments
in BW, ADG, and ADFI in the finisher phase
(P < 0.001)
