Avaliação de silagem do capim mori (Paspalum fasciculatum Willd ex Flüggé)

Abstract

The objective of this work was to evaluate the potential of Mori grass (Paspalum fasciculatum) for the preparation of silage. The experimental design used was entirely randomized, with five repetitions, composed of silages with three degrees of maturity of the grass (30, 45 and 60 days of regrowth after standardization cut). After 30 days the silages were opened and the DM, CP, FDN, FDA, MM, pH and [N-NH3 (%N total)] content of the silages was analyzed. The in-situ degradability of DM and FDN of the silages and Mori grass was also evaluated. The data were analyzed by SAS. Comparison of means of the silages was performed by the Tukey test at 5% probability. The protein in all ages of the grass meets the minimum dietary quality. With increasing age, the content of DM and CP decreases. In situ degradability for the ages of the grass did not change for the degradability of DM, changes were observed in the degradability of FDN at 45 and 60 days in the B fraction and in the DEF for the passage rates of 2 and 4%. Mori grass can be used for making silage.
