Forage mass,carrying capacity and daily weight gain of crossbred heifers in silvopastoral system or exclusive signalgrass pasture

摘要

Pasture degradation characterized by soil erosion,weed invasion,low forage yield and nutritive value and animal performance and productivity often is the result from mistaken pasture management.Silvopastoral systems are an option to overcome pasture degradation by promoting soil and water conservation,improved thermal animal comfort and forage nutritive value as well (Paciullo et al.2007 ).Nonetheless,the adoption of such system is hampered due to limited research data on the effect of factors influencing their efficiency.This study aimed at the comparison of a silvopastoral system with a monoculture of signal grass pasture ( Brachiaria decumbens cv Basilisk).
