How Are Warm-Season Pastures’ Nutritive Value and Fermentation Characteristics Affected by Open Pasture, Silvopasture, and Sward Herbage Maturity?

This study aimed to evaluate the forage mass and nutritional value (NV) of Guinea Massai grass (Megathyrsus maximus × Megathyrsus infestum) in an open pasture (OP) or silvopastoral system (SPS) at different stages development (SDs). The experimental design was completely randomized, with five replications. treatments were distributed a factorial scheme 2 4, corresponding types systems (OP SPS) four SD (vegetative stage—S1, pre-flowering—S2, full flowering—S3 maturity after flowering—S4). There no interaction stage plant any variables evaluated. production morphological components did not differ (p > 0.05) between SPS OP. However, they differed SDs ≤ 0.05), increasing linear effect for mass, percentage stem, dead material, decreasing leaf leaf: stem ratio. Only protein content < among chemical composition culture systems. shading caused by decrease NV, vitro dry matter digestibility compared advance increases higher proportions low such as material. Silvopastoral eucalyptus is effective prolongate grazing season, greater amount green leaves sward better without compromising herbage growing season.
