Representative samples of silage, concentrate and leftovers were collected daily to determine DM content. Dried samples of silage and concentrate were bulked over the week and analyzed for the content of crude ash, CP, NDF, ADF, acid detergent lignin (ADL) and WSC. Fresh silage samples were also taken at weekly intervals to determine pH, the concentrations of ammonia-N, ethanol, lactic acid and VFAs, and to evaluate particle size with the use of the New Penn State Forage Particle Separator [13].
