| The aim of the study was to evaluate the chemical composition and in vitro dry matter digestibility (IVDMD) of six grasses subjected to different irrigation depths and seasons. The experiment was conducted in a completely randomized arrangement with two replications in a split-split plot design. The treatments included plots with six grasses (Xaraés, Mombaça, Tanzania, Pioneiro, Marandu and Estrela), six irrigation depths for the split-plots (0%, 18%, 45%, 77%, 100% and 120% of the reference value provided by the tensiometer), and two seasons as the split-split plots (autumn/winter and spring/summer). A line source sprinkler system was used for application of the irrigation depths. Crude protein (CP), neutral detergent fiber (NDF) and IVDMD were evaluated... |
