Resumen
Descripción
Three pasture-based systems (PS) with bermuda grass (BG) + forage peanut + 75 kg of N ha -1 ; BG + common vetch + 75 kg of N ha -1 and BG + 150 kg of N ha -1 were evaluated. Lactating Holstein cows were used for evaluation and the experimental design was completely randomized. Forage mass, botanical and structural composition, da ily dry matter accumulation rate and stocking rate were evaluated. Samples were colle cted by hand-plucking method to analyze crude protein (CP), neutral detergent fiber (NDF), (ISDMD), in situ organic matter digestibility (ISOMD) and total digestible nutrients (TDN). Average forage production an d stocking rate were 13.8; 15.3 and 16.1 t ha -1 and 5.6; 6.4 and 5.5 UA ha -1 day -1 for PS respectively. Average CP and ND F were 16.4; 22.2 and 15.3%; 68.3; 65.7 and 66.3%; for ISDMD, ISOMD and TDN were 68.5; 70. 3 and 66.4%; 64.3; 63.2 and 65.3%; 57.3; 58.3 and 57.5%, for PS respectively. Best results were reported on bermuda grass mixed with common vetch.
