¹CON = Control diet, without crude glycerin, LCG = 7.5% added crude glycerin and 0.3% added salt (DM basis), LCGNS = 7.5% added crude glycerin and no salt (DM basis), HCG = 15% added crude glycerin and 0.3% added salt (DM basis), HCGNS = 15% added crude glycerin and no salt (DM basis).

²L = Linear effect of crude glycerin, Q = Quadratic effect of crude glycerin, S = Compares 0 and 0.3% salt in diets that contain crude glycerin, CON vs. CG = Contrast control vs. crude glycerin treatments.

³Calculated by multiplying gross final BW by 96% (i.e., 4% pencil shrink).

⁴Calculated by dividing hot carcass height by a common dressing percentage of 63.5%.

⁵G:F = weight gain per feed consumed.
