Nutrient intake and economic analysis of young bulls reared in silvopastoral systems with babassu palm trees in the Pre-Amazon region

SUMMARY This study evaluated the intake of dry matter (IDM), nutrients and the economic analysis of F1 young bulls from the cross between Nellore and Guzera on pastures of Urochloa brizantha cv. Marandu in silvopastoral systems composed of babassu palm (Attalea speciosa) and Marandu monoculture in the Pre-Amazon region of the state of Maranhão. Animals were evaluated in four systems consisting of 0, 80, 131, 160 palms ha-1, characterizing monoculture (MC), low density of palm trees (LDP), average density of palm trees (ADP) and high density of palm trees (HDP) during the rainy (RP) and dry (DP) periods. The dry matter intake, in g day-1, %BW and g kg-075 was influenced by the densities of babassu palm trees (P
