Conteúdo: |
Nutritional content of Brachiaria humidicola grass in relation to crude protein(CP), in vitro organic matter digestibility (IVOMD), and selenium (Se) asrelated to wet and dry seasons in the Amazon region of Marajó Island, Brazil,was determined. Twenty-four samples, 12 from the dry and 12 from the wetseason, were analyzed. Grass selenium concentrations were not influencedby season and the means were above the minimal requirement for beef cattle in both seasons (0.14 or 0.15 ppm). Factors other than rainfall may beinvolved. Crude protein concentrations were lower (P<.05) in the dry (3.5%)than in the rainy season (4.8%) and in both seasons were lower than thecritical level for cattle (<7.0%). The IVOMD means were extremely low,33.5% in the wet season and 33.6% in the dry season. These analytical valuesindicate that Brachiaria humidicola grown at Marajó Island has nutritionallimitations for grazing buffalo and cattle production |
