Resumen

ANRIQUE G., RENE  y  VIVEROS, MARIA PAZ. Effect of ensiling on chemical composition and rumen degradability of apple pomace. Arch. med. vet. [online]. 2002, vol.34, n.2, pp.189-197. ISSN 0301-732X.  http://dx.doi.org/10.4067/S0301-732X2002000200005.

evaluated. Rumen degradability was determined in situ by the nylon bag technique at 2, 6, 12, 24 and 36 hrs fermentation with 6 replicates per time and apple pomace type. Ensiling increased the relative contents of DM, crude protein (CP), crude fiber (CF) and acid detergent fiber (ADF) (43.7, 13.0, 14.3 and 18.4% respectively) and reduced the metabolizable energy content (4.9%). Degradability was greater in fresh compared to ensiled apple pomace (p<0.05), however, the advantage decreased from 26% at 2 hrs to 3.3% at 36 hrs fermentation (84.9 vs 82.2 %), 93-95% of the potential degradability was obtained at 36 hrs fermentation. Values for soluble, slowly degradable and undegradable fractions of fresh and ensiled pomace, respectively were: 26.5 and 13.8%; 62.3 and 75.7%; 11.2 and 10.5%; potential degradability and degradation rates were: 88.8 and 89.5%; 0.076 and 0.065 hr-1, respectively. In ensiled pomace the insoluble fraction contributed more to DM degraded at 36 hrs (73.4 vs 92.1%) suggesting a greater fiber degradability and a more uniform degradation pattern with time. Due to its higher fiber and insoluble fraction content, effective degradability was lower in ensiled apple pomace
