	BA, %
Item	0.00	1.00	SEM	P value
Urine pH	7.37	6.21	0.25	0.008
Hour in chamber, ppm
24 h average	2.87	1.10	0.53	<0.001
Last 3 h	5.33	2.47	1.03	<0.001
Last 5 h	5.00	2.38	1.02	<0.001
Last 7 h	4.78	2.27	0.93	0.001
Last 10 h	4.43	2.03	0.84	0.001

¹The experimental unit was a pen and each least squares mean represents 6 observations for urine pH and ammonia emission.

²Pigs were housed in a pen in an environmental chamber with an odor sensor for 24 h period for this study.
