Abstract

The objective of this work will be to evaluate the animal productivity, and the nutritive value of multispecies pastures under management strategies established in no-tillage area. Forage legumes Macrotiloma axillare, Neonotonia wightii, Calopogonium mucunoides, Stylosanthes guianensis and Aruana grass (Panicum maximum cv. Aruana) will be planted in October and November 2019, respectively. The multispecies pasture will be evaluated in four treatments of canopy height (15, 30, 45 and 60 cm) kept under continuous stocking and variable stocking rate by sheep in a randomized block design with four replications (16 paddocks of 500m2/ each) until April 2021. Monthly evaluations of forage mass, botanical and morphological composition of forage and grazing simulation samples, bromatological composition and digestibility of grazing simulation samples will be carried out. Animal performance will be measured in two tracer animals per experimental unit weighing every 28 days. It is expected to determine management goals of multispecies Aruana grass pastures and legumes for maximum presence of legumes in the forage mass and higher animal productivity. (AU)
