| Description | Two types of modified nano-montmorillonite (MNM) were developed by ion-exchange reactions using two different surfactants; sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CETAB), to prepare $MNM_{SDS}$ and $MNM_{CETAB}$, respectively. Both MNM types were on the nano-scale and had higher cation-exchange capacity values than NM clay. The $MNM_{CETAB}$ had the highest zeta potential (−27 mV) compared with the other clays. Effects of MNM types on in vitro ruminal batch culture fermentation, nutrient degradability, and methane $(CH_{4}$) emission compared with monensin were evaluated in vitro using a semi-automatic gas production system. The experimental treatments were the control (0 supplementations), monensin (40 mg/kg DM), and NM (5 g NM/kg DM), and two levels of $MNM_{SDS}$ and $MNM_{CETAB}$ were supplemented at 0.05 (low) and 0.5 (high) g/kg DM to the control basal feed substrate. Among the experimental treatments, the high dose of both MNM types reduced (p < 0.01) $CH_{4}$ production and ammonia concentrations compared with the control, while only $MNM_{CETAB}$ treatment tended to increase (p = 0.08) the truly degraded organic matter compared with monensin. All MNM treatments increased (p < 0.01) acetate molar proportions compared with monensin. The high $MNM_{CETAB}$ increased (p < 0.01) the in vitro ruminal batch culture pH compared with the control and monensin. The $MNM_{CETAB}$ supplemented at 0.5 g/kg DM is the most efficient additive to reduce $CH_{4}$ emission with the advantage of enhancing the in vitro nutrient degradability of the experimental feed substrate. These results indicated that MNM could modulate the in vitro ruminal fermentation pattern in a dose- and type-dependent manner. |
