Two treatments (cattle diet) were used in anaerobic digestion of finishing cattle manure. Diet 1 contained 82.5% dry rolled corn (DRC) (CONT) and diet 2 contained 40% wet distillers grains plus solubles (DM basis) replacing DRC (WDGS). Cattle were housed in stanchions for 3 d with complete manure collection in a cement pit. Manure (feces and urine) was sampled and analyzed for minerals, DM and OM. Manure collected was weighed into individual allotments based on DM and frozen. Continuously stirred anaerobic digesters (n = 7, 1 L capacity) were inoculated and maintained for 5 mo before the trial to ensure …
