The study was conducted to determine chemical composition and in vitro digestibility of sugar beet pulp (SBP) in cattle. Different ensiled SBP samples were procured from dairy farms near university and analyzed for chemical composition. Six complete diets were prepared by substituting maize fodder with SBP @ 20,40,60,80 and 100 percent and subjected to in-vitro gas production to estimate DM and NDF digestibility. The proximate analysis of different samples of SBP revealed that it has similar composition that of maize. The net gas production, NDF digestibility and organic matter digestibility was significantly (P≤0.05) higher at 100% of inclusion than others (266.22 ml/24 hr, 75.10% & 89.18% respectively). The ammonia level differed statistically (P≤0.05) and gradually decreased as inclusion level of SBP increased. The fermentable CO2, fermentable CH4 and ME was significantly (P≤0.05) higher at 80%level (49.93mmol, 32.94mmol & 9.30MJ/kg DM respectively) than the others diets. The total VFA concentration was significantly (P≤0.05) higher at 100% (6.94mM/dl). The concentration of acetate and propionate was significantly (P≤0.05) higher at 100% of inclusion (4.86mM/dl & 1.54mM/dl) while the concentration of butyrate, isobutyrate, valerate and isovalerate was significantly (P≤0.05) higher at 80% inclusion level (0.03 mM/dl, 0.43 mM/dl, 0.05 mM/dl & 0.04 mM/dl respectively). The acetate to propionate ratio was significantly (P≤0.05) higher at 80% level. It was concluded that maize fodder can be replaced by SBP completely.
