- aAll treatment conditions were stored anaerobically in the dark at 20% solids. Mean (n = 3) and standard deviation are presented
- bTotal organic acids refers to the sum of succinic, lactic, formic, acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids present after storage
- cRepresent statistically significant difference between 30 and 180 days treatments based on likelihood probability analysis using 5% confidence intervals
