Maass, Brigitte L.Hanson, JeanHacker, JBCoradin, Lídio[Report of a working group on tropical and subtropical forage genetic resources (second meeting), held at CIAT, Cali, Colombia 6-8 April 1994]Report of a working group on tropical and subtropical forage genetic resources (second meeting), held at CIAT, Cali, Colombia 6-8 April 1994

We conducted an experiment to determine the effects of concentration and astringency of extractable and bound condensed tannins (CT) in tropical legumes on intake, digestibility, and nitrogen (N) utilization by sheep. The test legumes (Desmodium ovalifolium and Flemingia macrophylla) had similar ...


Barahona Rosales, RolandoLascano, Carlos E.Cochran, RMorrill, JTitgemeyer, EC[Intake, digestion, and nitrogen utilization by sheep fed tropical legumes with contrasting tannin concentration and astringency]Intake, digestion, and nitrogen utilization by sheep fed tropical legumes with contrasting tannin concentration and astringency

A trial with sheep (housed in metabolic cages, and fitted with ruminal and duodenal cannulas) fed sun-dried forage of two Calliandra calothyrsus provenances (San Ramon —CIAT 22310 and Patulul CIAT— 22316) harvested in sites with contrasting soil fertility was carried out to further define the bio...


Lascano, Carlos E.Avila Vargas, PStewart, J[Intake, digestibility and nitrogen utilization by sheep fed with provenances of Calliandra calothyrsus Meissner with different tannin structure]Intake, digestibility and nitrogen utilization by sheep fed with provenances of Calliandra calothyrsus Meissner with different tannin structure

En épocas de lluvia (mayo de 2006) y de sequía (agosto de 2006), en tres sitios de la zona de ladera de los municipios de Bolívar, Sevilla y El Dovio, se evaluó mediante metodologías participativas el proceso de adaptación de tecnologías forrajeras. Se aplicaron evaluaciones abiertas, absolutas y...


Cárdenas Villarraga, Paula AndreaDurán Castro, Carlos V.Roa Velasco, J.I.[Selección de forrajeras para zona de ladera del norte del Valle del Cauca (Colombia) mediante metodologías participativas = Selection of forages species for hillsides zones of northern part of north of Valle del Cauca (Colombia) by means of participative methodologies]Selección de forrajeras para zona de ladera del norte del Valle del Cauca (Colombia) mediante metodologías participativas = Selection of forages species for hillsides zones of northern part of north of Valle del Cauca (Colombia) by means of participative methodologies

En el CIAT, Centro Experimental, Estación de Santander de Quilichao, (Cauca, Colombia) durante 1980 y 1981 se observó la presencia de marchitez en plantas de Zornia spp., asociada a Corynebacterium flaccumfaciens. En razón de ese registro y del riesgo que implicaba su presencia en uno de los siti...

A short-term improved fallow system based on forage legumes is suggested for crop-livestock farming systems in subhumid West Africa targeted to enhance soil fertility and dry season feed for cattle. At two sites, 13 legume species were compared with the natural fallow vegetation, the nutritive va...
