Avaliação bromatológica do capim massai, em diferentes idades de corte

Abstract

This work was carried out to evaluate the nutritional quality of Megathyrsus maximum cv Massai grass harvested at different cutting ages (15, 25, 35, 45, 55 and 65 days). Using a block desing with four replications. It was observed that the dry matter (DM) contents had a linear growth (P<0.05) with age influence, being the highest value at 65 days with 51.10%. Crude protein (CP) content was negatively influenced by age, reaching 5.56% at 65 days. Results of NDF and FDA did not obtain significant results, but with numerical increase due to the advance of forage age. The NIDN variable obtained a negative decrease, having 5.44% at 15 days, reaching 2.42% at 65 days. The values of ether extract (EE) found had significant differences between the treatments observed, with the highest result at 25 days (1.90%) and the lowest result at 65 days (0.35%). Based on the results obtained, it is concluded that the Massai has better quality around 35 days in the period evaluated.
