dc.description.abstractThe ruminal degradability of dry matter (DM) and neutral detergent fiber (NDF) of 9 sugarcane varieties ensiled 15 months after planting was evaluated, using 3 fistulated Holstein x Zebu cows and incubation periods of 0, 6, 12, 24, 72 and 96 h in a randomized complete block design. Dry matter, crude protein (CP), mineral matter (MM), NDF, pH and in-situ degradability levels were determined. There were significant differences in composition of all evaluated param-eters in the silages, except for CP, with the following variations: DM (19.7–23.2%), CP (2.70–3.47%), MM (3.2–5.2%), NDF (67.6–73.8%) and pH (3.8–4.2). The DM fraction ‘a’ differed among sugarcane varieties, with SP 801816 presenting the highest soluble fraction (26.83%). Effective degradability (ED) of DM (32.7–40.9%) and degradation rate ‘c’ did not differ among varieties. The ED of NDF and fraction ‘a’ did not differ among silages, but there were significant differences in fraction ‘b’, with a variation from 36.4 to 41.2%. Highest NDF ED occurred for the varieties RB 835486 (22%) and SP 791011 (21.1%). Further studies with these two varieties with the addition of inoculants and additives at ensiling are needed along with feeding studies to determine animal performance data.pt_BR
dc.description.abstractSe evaluó la degradabilidad de la materia seca (MS) y la fibra detergente neutra (FDN) de ensilajes de 9 variedades de caña de azúcar, ensiladas 15 meses después de la siembra, utilizando 3 vacas (Holstein x Cebú) con cánula ruminal. Las muestras se incubaron durante 0, 6, 12, 24, 72 y 96 h y se determinaron los niveles de MS, FDN, proteína cruda (PC), materia mineral (MM), pH y la degradabilidad in situ. El diseño experimental fue bloques al azar con 9 trata-mientos y 3 repeticiones. Los resultados mostraron diferencias (P<0.05) en la composición química de los ensilajes, excepto para PC, con las variaciones siguientes: MS (19.7–23.2%), PC (2.70–3.47%), MM (3.2−5.2%), FDN (67.6–73.8%) y pH (3.8–4.2). La fracción soluble (‘a’) de la MS varió entre las variedades de caña, entre ellas la SP 801816 que presentó el valor más alto (26.83%). La degradabilidad efectiva (DE) de la MS (32.7–40.9%) y la tasa de degrada-ción (‘c’) no difirieron entre variedades. La DE de la FDN y la fracción ‘a’ no difirieron entre ensilajes, pero se encon-traron diferencias en la fracción potencialmente degradable (‘b’) con variaciones desde 36.4 hasta 41.2%. Los valores más altos de la DE de la FDN ocurrieron con las variedades RB 835486 (22%) y SP 791011 (21.1%). Se sugiere la realización de estudios con estas 2 variedades usando inoculantes y aditivos al ensilar y determinando el desempeño animal.pt_BR
