Rumen parameters	Experimental diets (different physical forms)			SEM	P-value
Rumen parameters	Complete feed mash	Complete feed pellet	Complete feed block	SEM	P-value
pH	6.62	6.33	6.58	0.19	0.05
Ammonia N, mg/dL	14.44^b	14.68^b	15.32^a	0.17	0.02
TVFA, mmol/L	101.2	100.1	102.4	1.2	0.2
Acetate, mol/100 mol	61.05^ab	60.00^b	61.70^a	0.32	0.02
Propionate, mol/100 mol	28.25	28.15	28.50	0.22	0.30
Butyrate, mol/100 mol	8.85	8.95	8.95	0.11	0.50
Isovalerate, mol/100 mol	1.50	1.45	1.60	0.10	0.50

Acetate: propionate	2.16	2.13	2.12	0.03	0.40

SEM = standard error of means; TVFA = total volatile fatty acid.

^a,b Means with different superscripts in the same row differ significantly (P < 0.05).
