- a, b, cMeans within a row with different subscripts differ (P < 0.05).
- 1Treatments were diets containing barley + basal diet (B), barley and corn + basal diet (BC), and barley and beet pulp + basal diet (BB).
- 2peNDFm = physically effective NDF, based on DM retained on sieve 1.18 mm [13].
- 3peNDF>8 = physically effective NDF, determined as the proportion of DM retained on sieves of the original version of Penn State particle separator [10].
- 4peNDF>1.18 = physically effective NDF, determined as the proportion of DM retained on sieves of the new version of Penn State particle separator [11].
- 5NDSC = Neutral detergent soluble carbohydrate.
