Methane (CH4) is a greenhouse gas (GHG) produced and released by eructation to the atmosphere in large volumes by ruminants. Enteric CH4 contributes significantly to global GHG emissions arising from animal agriculture. It has been contended that tropical grasses produce higher emissions of enteric CH4 than temperate grasses, when they are fed to r...
Scarcity of quantity and quality feed has been a key constraint to productivity of smallholder crop-livestock systems. Tropical forages include a variety of annual and perennial grasses, herbaceous and dual-purpose legumes, and multipurpose trees and shrubs. They have been promoted in Sub-Saharan Africa (SSA) for increasing livestock productivity a...
A report on the tropical forage germplasm collection conserved in the CIAT genebank is presented. Emphasis is firstly on the assembling of the collection during 1972−1993 through about 70 major and minor collecting missions in tropical America, Africa and Southeast Asia. Along with introductions from existing collections, currently some 1,600 acces...
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 con bloques al azar, cuya parcela principal fue la esp...
Livestock systems in the tropics can contribute to mitigate climate change by reducing greenhouse gas (GHG) emissions and increasing carbon accumulation. We quantified C stocks and GHG emissions of 30 dual-purpose cattle farms in Nicaragua using farm inventories and lifecycle analysis. Trees in silvo-pastoral systems were the main C stock abovegrou...
This was a trial on evaluating Napier grass cultivars performance under two contrasting environments (lowlands and highlands) in Kenya.
