Nutritional quality of Tithonia diversifolia Hemsl. A Gray under three planting systems in the high tropic.
The aim of this study was to compare the chemical composition and tannins content of botón de oro (Tithonia diversifolia) obtained under three different planting systems. The work was developed in Santa Martha farm, in the municipality of Guarne (Antioquia-Colombia), located at 2453 meters above sea level, from October 2013 and July 2014. After 56 days of the uniformity cut was analyzed contents of dry matter (12.74%, 12.90%, 12.45%), protein crude (14.1%, 12.76%, 13.31%), ash (16.19%, 15.50%, 16.00%), calcium (2.86%, 3.05%, 2.93%), phosphorus (0.27%, 0.25%, 0.27%), neutral detergent fiber (53.81%, 50.21%, 52.80%), acid detergent ber (48.18%, 48.87%, 48.47%), total nonstructural carbohydrates (8.50%, 8.35%, 7.82%), total tannin (0.08%, 0.11%, 0.08%) and total phenols (0.20%, 0.29%, 0.24%), for complete plants harvested in plots established by cuttings, by sexual seed handled in vitro and by sexual seed handled in seedlings, respectively; only differences in total phenols were found (p≤0.05). The method of establishment has no bearing on the nutritional composition in conditions under which this study was conducted; and at content of secondary metabolites no be high, is not to expect infuence in the palatability, digestibility nor consumption of dry matter.

El objetivo de este trabajo fue comparar la composición bromatológica y el contenido de taninos del forraje de botón de oro (Tithonia diversifolia) obtenido bajo tres sistemas de siembra. El trabajo se desarrolló en la finca Santa Martha, en el municipio de Guarne (Antioquia-Colombia), ubicada a 2453 msnm, entre octubre de 2013 y julio de 2014. A los 56 días del corte de uniformización, se analizaron los contenidos de materia seca (12,74%, 12,90%, 12,45%), proteína cruda (14,1%, 12,76%, 13,31%), cenizas (16,19%, 15,50%, 16,00), calcio (2,86%, 3,05%, 2,93%), fósforo (0,27%, 0,25%, 0,27%), bra detergente neutro (53,81%, 50,21%, 52,80%), fibra detergente ácido (48,18%, 48,87%, 48,47%), carbohidratos totales no estructurales (8,50%, 8,35%, 7,82%), taninos totales (0,08%, 0,11%, 0,08%) y fenoles totales (0,20%, 0,29%, 0,24%), para plantas completas cosechadas en parcelas establecidas a partir de estacas, semilla sexual manejada in vitro y semilla sexual en almácigos, respectivamente; solo se encontraron diferencias para fenoles totales (p≤0,05). El método de establecimiento no incidió sobre el contenido de nutrientes bajo las condiciones en que se realizó este estudio, y al contenido de metabolitos secundarios no ser alto, se espera que no influyan sobre la palatabilidad, el consumo ni la digestibilidad de la materia seca.
