Andersson, Meike S.Lascano, Carlos E.Schultze-Kraft, RainerPeters, Michael[Forage quality and tannin concentration and composition of a collection of the tropical shrub legumes Flemingia macrophylla]Forage quality and tannin concentration and composition of a collection of the tropical shrub legumes Flemingia macrophylla

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...

With the purpose of determining under field condi Lions the quantity of rainfall that moves vertically to several depths in the Altillanura, a soil Tipyc Haplustox isohipertérmico caolinítico of the municipality of Port López (Meta) was selected, worked during several years (2,4 and 6 traîl passe...


Carulla, Juan E.Lascano, Carlos E.Klopfenstein, T[Reduction of tannin level in a tropical legume (Desmodium ovalifolium) with polyethylene glycol (PEG): Effects on intake and N balance digestion and absorption by sheep]Reduction of tannin level in a tropical legume (Desmodium ovalifolium) with polyethylene glycol (PEG): Effects on intake and N balance digestion and absorption by sheep

A feeding trial with sheep was carried out at the Centro Internacional de Agricultura Tropical (CIAT) in Colombia to investigate the concept of using mixtures of sun-dried tropical shrub legumes to dilute tannin levels in the diet and improve nitrogen (N) utilisation by ruminants. Intake, digesti...
