Table 2.

Effects of 3-nitrooxypropanol (3-NOP) dosage levels (PLA: 0, LOW: 73, MED: 160, and HIGH: 1200 mg of 3-NOP/kg of feed DM) and low- (LC) or high- (HC) concentrate feed proportion in the diet (CFP) on dry matter degradation (DMD), apparent organic matter degradation (OMAD), and neutral-detergent fibre degradation (NDFD) (g/kg DM).

^† Values presented as LS means. ^§ SEM, standard error of the means. ⁺ Effects of CFP, 3-NOP dose, and interactions between them; L, Q, p-values for linear and quadratic effects of 3-NOP; ß_L > F, ß_Q > F, probability under H₀ that an F-distributed random variable exceeds observed F, for the difference in the linear and quadratic regression coefficients between LC and HC. Significant values (p ≤ 0.05 are highlighted in bold).
