Table 3 Supplementation effects of unmodified montmorillonite (UM) and modified nano-montmorillonite by sodium dodecyl sulfate (MNM) on ruminal gas production (GP), methane emission (CH4), true degraded organic matter (TDOM), and true degraded neutral detergent fiber (TDNDF)

From: Potential of montmorillonite modified by an organosulfur surfactant for reducing aflatoxin B1 toxicity and ruminal methanogenesis in vitro
