Abstract
In ruminants, selenium is an essential trace element and has a variety of biological functions, but its importance for rumen microbes is still not fully understood. The goal of the current study is to investigate the effects of prepared selenium nanoparticles (Se-NPs) at various concentrations (0.2, 0.4, 0.6, 1, 2, and 3 mg of Se-NPs/Kg DM for T1, T2, T3, T4, T5, and T6 groups, respectively) on in vitro ruminal feed degradation, fermentation, and total gas production. A supplemented diet with Se-NPs at 0.2 mg/kg DM caused the highest increase (P<0.05) in degradability values of dry matter (DM) by 14.3%, organic matter (OM) by 9.1%, neutral detergent fiber (NDF) by 3.2%, acid detergent fiber (ADF) by 6.8%, values for total gas production (TGP), acetic acid by 20.3%, propionic acid by 35%, and butyric acid by 3.2% with a switching fermentation pattern from acetate to propionate as compared to the control diet. In comparison to the control diet, supplemented diets with Se-NPs at 2 or 3 mg/kg DM significantly reduced TGP and concentrations of acetic acid, propionic acid, and butyric acid. The supplementation of the diet with 0.2 mg of Se-NPs is sufficient to improve ruminal digestibility and fermentation.
