| description | This article summarizes the information obtained in several trials on the nutritive quality, intake, and acceptability of Cratylia argentea.In addition, results are presented of the use of this legume as a supplement for sheep fed low-quality forage and for dairy cows grazing during the dry and rainy seasons. The nutritive value of C. argentea, measured in terms of crude protein and in vitro digestibility, is similar to that of other common shrub legumes (i.e., Gliricidia sepium, Calliandra callothyrsus, and Erythrina poeppigiana) that are, however, only marginally adapted to acid soils Cratylia argentea has only trace amounts of tannins; its nutritive value, however, is higher than that of other semi-shrub legumes well adapted to acid soils, which have high levels of tannins (i.e., Flemingia macrophylla and Codariocalyx gyroides). The intake of immature and fresh forage of C. argentea is low, but increases when the forage withers or dries in the sun, or when offered mature. This effect on intake is possibly associated with the presence of an unidentified non-nutritional compound. The inclusion of increasing levels of C. argentea (0 percent to 40 percent of the forage on offer) in mixtures with low-quality grass increased total intake linerly, but similarly decreased the digestibility of the sheep diet. |

En este artículo se resume la información disponible de algunos ensayos sobre calidad nutritiva, consumo y aceptabilidad de Cratytia argentea. Además, se presentan resultados sobre la utilización de esta leguminosa como suplemento a ovinos alimentados con forrajes de baja calidad y a vacas de leche en pastoreo en épocas seca y lluviosa. El valor nutritivo de C. argentea medido en términos de proteína cruda y digestibilidad in vitro es similar al de otras leguminosas arbustivas conocidas (i.e. Gliricidia sepium, Calliandra callothyrsus y Erythrina poeppigiana), pero marginalmente adaptadas a suelos ácidos. Sin embargo, el valor nutritivo de C. argentea con trazas de taninos es mayor que el de otras leguminosas semiarbustivas con altos niveles de taninos (i.e., Flemingia macrophylla y Codariocalyx gyroides) y con buena adaptación a suelos ácidos. El consumo de forraje de C. argentea en estado inmaduro y fresco es bajo, pero aumenta cuando el forraje se marchita o se seca al sol, o cuando se ofrece maduro; esto posiblemente esté asociado con la presencia de algún compuesto antinutricional no identificado. La inclusión de niveles crecientes de C. argentea (0 por ciento a 40 por ciento del forraje ofrecido) en mezcla con una gramínea de baja calidad aumentó en forma lineal el consumo total, pero disminuyó en la misma forma la digestibilidad de la dieta consumida por ovinos. 1996 2017-03-14T08:36:17Z 2017-03-14T08:36:17Z Conference Paper https://hdl.handle.net/10568/80255 es Open Access International Center for Tropical Agriculture Empresa Brasileira de Pesquisa Agropecuária Centro de Pesquisa Agropecuária do Cerrado (CPAC) Lascano, Carlos E.. 1996.
