Table 4.

BW measurements of drylot heifers receiving corn stalk-based diets with or without 150 mg/d of monensin at a maintenance level of intake

Item	Day of study						SEM^b	Probability^a
Item	0	3	14	28	42	161	SEM^b	Treatment	Day
BW, kg
Control	472^a	469^a	448^a	461^a	457^b	525^c	10.9	0.08	<0.01
Monensin	494^a	493^a	486^a	493^a	488^a	556^b	10.9
BW change, kg^c
Control	0^a	−3.4^a	−10.6^a	2.6^a	−3.6^a	68.4^b	3.78	0.32	<0.01
Monensin	0^a	−1.0^a	−6.8^a	6.6^a	−4.1^a	67.9^b	3.57

^aNo treatment × day interactions present (P ≥ 0.90).

^bPooled SE of least squares means (control n = 7; monensin n = 8).

^cBW change was calculated as the difference in BW from the previous weigh day.

^a,b,cWithin a row, means across days without a common superscript differ (P ≤ 0.05).
