oats, by-product, ammonia, digestibility
Oat mill by-product (OMB, approximately 80% oat hulls) was treated with 0, 1%, 3%, or 5% NH3 and 10%, 20%, 30%, 40%, or 50% H2O (4 x 5 factorial design) and allowed to react for 28 days. Samples were analyzed for in vitro dry matter digestibility (IVDMD), crude protein (CP) and fiber content (NDF, ADF, ADL). Treatment with 3% NH3 and 20% H20 resulted in maximum improvement of IVDMD. CP was increased and NDF decreased due to treatment. Nutritional value of OMB can be improved by NH3 treatment.
