Replacing wheat bran by corn gluten feed without steep water in complete dog food

Twenty-four adult Beagles were utilised to evaluate the partial replacement of wheat bran with corn gluten feed without steep water on digestibility and characteristics of faeces. The treatments were 0 (no substitution), 30, 60 or 90 g/kg of corn gluten without steep water. There was no effect (P>0.05) on the digestibility coefficients (g/kg) of dry matter (0.771), organic matter (0.806), crude protein (0.813), ether extract (0.798), crude fiber (0.393), neutral detergent fiber (0.425), acid detergent fiber (0.286) and crude energy (0.812), whilst there was effect (P<0.05) on the digestible and metabolizable energy. There were effects (P<0.05) for dry matter and pH of faeces but no effect (P>0.05) was found on the remaining fecal characteristics: excretion for 100 g of food (56.77 g), excretion (129.6 g/day and 49.0 g dry matter/day), score (3.90), dry matter excretion for 100 g of food (22.86 g), buffering capacity (BC) at pH 5 (57.81), ammonia nitrogen (1.46 g/kg of fecal dry matter) and water balance (333.25 mL/day), in vivo and in situ gas production (P>0.05). Corn gluten feed without steep water can be utilised to replace up to 90 g/kg of wheat bran without causing negative effect on the digestibility and characteristics of faeces.
