In Vivo Assessment of Dietary Supplementation of Magnetic Bentonite Nanocomposites in Baluchi Male Lambs Diets: Effects on Ruminal Fermentation, Nutrients Digestibility and Lamb Performance (Effect of Magnetic Bentonite Nanocomposites on Baluchi Male LambsPerformance)

This study aimed to evaluate in vivo dietary supplementation of magnetic bentonite nanocomposites onruminal fermentation, nutrients digestibility and performance in Baluchi male lambs. Twelve Baluchi male lambs[30.95 ± 2.41 kg body weight (BW), 5-6 months] were randomly divided into four experimental diets (n = 3 pergroup). The dietary treatments were: (1) control (basal diet without supplementation); (2) natural bentonite (NB) (20g/kg DM); (3) bentonite plus (BP) (0.5 g/kg DM) and (4) magnetic bentonite nanocomposites (MBNC) (0.5 g/kg DM).There was significant difference for final BW (P< 0.001), average daily gain (P< 0.007), dry matter intake (P< 0.001)and nutrients digestibility (P< 0.001) between diets. The pH (P< 0.001), NH3-N (P< 0.001), TVFA (P< 0.001), acetate(P< 0.001), propionate (P< 0.001) and acetate to propionate ratio (P= 0.001) differed between treatments. Theseresults indicated that modifying bentonite structure to nanocomposite improves chemical stability, physicochemicalproperties, and their efficiency as feed additives.
