Summary
O objetivo desse trabalho foi avaliar dois sistemas forrageiros (SF) com capim elefante (CE) + azevém (AZ) + espécies de crescimento espontâneo (ECE) + trevo branco, como SF1; e CE + AZ + ECE + amendoim forrageiro, como SF2. O capim elefante foi plantado em linhas afastadas a cada 4m de distância entre elas. No período hibernal foi semeado azevém entre as linhas formadas pelo capim elefante; em um sistema foi semeado o trevo branco e em outro foi preservado o amendoim forrageiro. O delineamento experimental foi o inteiramente casualizado, com dois tratamentos (SF), duas repetições (piquetes) e parcelas subdivididas no tempo (pastejos). Foram avaliadas a massa de forragem inicial (MF), a composição botânica e a carga animal. Foram coletadas amostras pelo método de pastejo simulado para análise da proteína bruta (PB) da forragem. Durante o período experimental (331 dias) foram conduzidos sete pastejos. Os valores médios da MF e lotação foram de 2968; 2905 kg de MS/ha e de 1,93; 1,65 UA/ha para os respectivos SF. No período hibernal foram observados teores elevados de PB para o capim elefante. Houve similaridade entre as pastagens quanto à produtividade e PB da forragem.
Summary translation
The objective of this research was to evaluate of two pasture-based systems (PS) with elephantgrass (EG) + ryegrass (RG) + spontaneous growing species (SGS) + white clover, for PS1 and EG + RG + SGS + forage peanut, for PS2. EG was planted in rows with a distance of 4m each one of them. In cool-season, ryegrass was sowed between rows of EG; white clover was sowed and forage peanut was preserved on respectively PS. Experimental design was completely randomized with two treatments (PS) two replications (paddocks) in complete split-plot time (grazing cycles). The initial herbage mass, botanical composition and stocking rate were evaluated. Samples were collect by collected by the hand-plucking method to analyze the crude protein (CP). Seven grazing cycles were performed during the experimental period (331 days). The mean values of dry matter of initial forage mass and stocking rate were 2968; 2905 kg/ha and 1.93; 1.65 UA/ha for respective PS. Higher values of CP of EG were observed in coolseason. Similar results on productivity and forage CP were observed between pastures.
