Abstract

Season and grazing may change pasture responses even in innovative, sustainable crop-livestock-forest (ICLF) systems. The objective of this work was to evaluate the initial dynamics of Urochloa brizantha cv. Piatã pastures grazed by buffaloes under continuous stocking in open pasture system (OP), ICLF with African mahogany (Khaya ivorensis) (ICLF-M) and ICLF system with teak (Tectona grandis) (ICLF-T) over time across the first dry and rainy seasons. Mass and crude protein of forage were evaluated every 28 days over a 252-days period. Forage mass was lower in the ICLF systems than in the OP system in the dry season. In contrast, ICLF-T system delivered forage with the highest crude protein content in this season. In the rainy season, no difference between systems was observed. Forage mass declined in all systems over time across the dry and rainy season due to grazing. Crude protein contents also declined within each season, but the contents were higher in the rainy season than in the dry season. The season changes the productivity and quality of forage while the grazing determinates the initial dynamics of pastures in ICLF systems.
