64Biofuel co-products as livestock feed – Opportunities and challengesand sorghum wet DG because differences between the twosources were also probably confounded by the concentrationof solubles in the products. Six ruminally cannulatedsteers were fed either SFC- or DRC-based diets containingno wet DG or 20 percent low- and high-NDF wet DG in an insitu digestion study. The Latin square design was such thateach steer received each diet, and each DG source was incubated(0, 2, 4, 8, 16, 24, 48 and 96 hours) only in steers fedthe same DG source. The wet DG samples, but not the insitu residues, were extracted with acetone to remove fat. Anexponential model was used to estimate the rapidly solublefraction (A), potentially degraded fraction (B), and fractionalrate of degradation of the B fraction (c). Effective ruminaldegradability (ERD) was calculated using the equation:ERD = A + [(B × c)/(c + k)]with a passage rate (k) = 0.05/hour. Source of DG had thegreatest effect on the parameter estimates (Table 2). ForDM disappearance, the low-NDF DG source had a larger Afraction (P
