Resumen
Silages from three cultivars of triticale (X Triticosecale wittimack) were evaluated at the UNESP, Jaboticabal, Brazil. The cultivars FCA VJ-CB-01, FCA VJ-CB-02, and FCA VJ-CB-03 were harvested for silage in three growing stages of maturity; beginning of flowering, (S1), milk stage (S2), and dough stages (S3). Data were analyzed by randomized complete block with three replications. The DM (%) values increased while the CP (%DM) and buffering capacity (me HCl/100 g DM) decreased with plant development. Silages of plants harvested at S3 stage had higher pH and N-NH3 values compared to the S1 and S2 silages. The soluble carbohydrates contents (%DM) were higher at the S2 stage (16.9%) and were not different at the S1 (8.7%) and S3 (9.2%) stages. The crude energy contents (Kcal/kg MS) increased while the ADF, NDF, cellulose, and hemicellulose (DM%) decreased due to the presence of dough grains. This was not observed with the lignin contents. The IVDMD values were 66.3, 60.1 and 58.9%, for plants harvested at the S1, S2, and S3 stages, respectively. The results showed that there was no difference among for chemical composition, crude energy, and for IVDMD.
