1NS = no slurry application; S0 = slurry application immediately after baling the first cutting; S14 = slurry application 14 d after baling the first cutting.
2Probability of the contrasts S and D where S = no slurry application vs. the mean of S0 and S14 and D = S0 vs. S14.
3DMI = dry matter intake; OMI = organic matter intake; DMD = dry matter digestibility; OMD = organic matter digestibility; DDMI = digestible dry matter intake; DOMI = digestible organic matter intake.
4SEM = pooled standard error of the mean.
5There were no moisture × slurry interactions (P ≥ 0.35) for variables other than NDFD.
