Measurements were carried out at the Carimagua Research Station in the Llanos of Colombia, to (1) further characterise the nutritional value of A. pintoi (CIAT 17434) in association with B. dictyoneura cv. Llanero during the rainy (RS) and dry (DS) season, and (2) assess legume selectivity of res...

Se evaluó el efecto de tres edades de rebrote (tres, seis y nueve semanas) sobre la producción de forraje, calidad nutricional y perfil de ácidos grasos en gramíneas de pastoreo (diez cultivares y un híbrido)y en gramíneas de corte (cuatro cultivares). Se utilizó un diseño de parcelas divididas c...

Regulating nitrification could be a key strategy in improving nitrogen (N) recovery and agronomic N-use efficiency in situations where the loss of N following nitrification is significant. A highly sensitive bioassay using recombinant luminescent Nitrosomonas europaea, has been developed that can...

he aim of most publicly funded research and development of forages in the subtropics and tropics of the developing world is to improve the livelihoods of smallholder farmers. In order to achieve this goal, technical options are sought which not only contribute to alleviation of poverty and improv...

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 ...

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...
