Salts were investigated at 2 inclusion levels (IL; IL3 = 3% and IL6 = 6% of DM). Incubations were performed with (n = 3) or without (n = 3) the addition of casein and cysteine (C&C). Enumeration of in vitro NDF digestibility and methane (CH4) production was performed for all samples. Results and Discussion: With C&C inclusion, S1 produced more gas than S5 and reduced lag time compared with S6 and S7. The S5, S6, and S7 had lower CH4 production relative to S3. The IL3
