Uno de los problemas subyacentes del cambio climático, que afectan en gran medida a la ganadería en países del trópico, es la estacionalidad en la producción de forraje (Arreaza et al., 2012, Mendieta et al., 2015). Periodos prolongados de sequía y de lluvias repercuten en la disponibilidad y calidad de la alimentación consumida por los animales, l...

One of the underlying problems of climate change that greatly affect livestock production in tropical countries is seasonality in forage production (Arreaza et al., 2012; Mendieta et al., 2015). Prolonged periods of drought and rain affect the availability and quality of the feed consumed by the animals, leading to both biological and economic loss...

In the Colombian high-altitude tropics (2,200–3,000 m.a.s.l.), Kikuyu grass (Cenchrus clandestinus) is the main feed source for the dairy system. This grass species has good characteristics regarding adaptability and productivity, but is affected by frost, grass bugs (Collaria spp.) and precipitation-related production seasonality. Forage deficits...
Article
Large-scale conversion of natural ecosystems to grazed grasslands and subsequent soil degradation due to overgrazing and inadequate pasture management in tropical agroecosystems urgently call for sustainable intensification of grazing systems, i.e. increasing animal productivity while maintaining or improving soil quality and ecosystem services. We...

This info note summarizes the objectives, scope, and intervention logic of the livestock component of the PDET Routes project, which is implemented in four municipalities in Caquetá. The conditions that converge there, such as the high and growing rate of deforestation, environmental impacts, productive orientation, and types of land tenure, enable...

Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia. Despite the great potential of legumes in cattle production, their adoption and use throughout the tropical world remain limited. While this is largely attributed to factors such as limited knowledge or access to credit, lack of in...

Despite the great potential of legumes in cattle production, their adoption and use remain limited. This is largely attributed to factors such as limited knowledge or access to credit, but also missing information on the viability and profitability of the technology can influence the adoption decision. The objective of this study is to evaluate the...

El género Leucaena Benth es un grupo de especies leñosas dentro de la tribu Mimoseae. El centro de biodiversidad biológica de Leucaena se localiza en el suroeste de México en el estado de Oaxaca. El nombre de Oaxaca deriva precisamente de oaxin, nombre dado a los frutos y árboles de este género de leguminosas (Zarate 1994). La diversidad y presenci...

Forage-based cattle systems play a key role in rural economies of developing countries in terms of food security and poverty alleviation. However, they are often related to being a major cause of negative environmental impacts by contributing to increased greenhouse gas (GHG) emissions, land degradation, and reduction of biodiversity. As a result o...

The Colombian Amazon region presents one of the country’s highest rates of rural poverty and inequality. During the past years, the region has also experienced growing rates of deforestation and illicit crop production, and is currently facing the various opportunities and challenges derived from the ongoing peace process. In the light of of this s...

◼ The RUMINANT model qualifies as an advanced or "Tier 3" method for estimating emissions from enteric fermentation in ruminant livestock. ◼ The RUMINANT model was validated for enteric methane emissions from cattle in the tropical lowlands (Cauca Valley) of Colombia using six different diets given to feeder steers in 2017. ◼ There was a good corre...

The increase in global population and changes in people’s lifestyles and diets during the last years have generated a high demand for animal protein sources. In Colombia, most of the area dedicated to livestock production is managed under extensive and inefficient production systems. The International Center for Tropical Agriculture (CIAT) is worki...

Cattle production in tropical countries is based on the use of extensive grazing systems, which are inefficient systems and generate low levels of profitability. Cattle production, thus, has high emissions per unit of output.  Globally, beef from beef cattle systems emits more greenhouse gases per unit of output than any other agricultural product...

 La producción ganadera se basa principalmente en el uso de sistemas extensivos de pastoreo, el cual es un sistema ineficiente que genera niveles bajos de rentabilidad y por ende altas emisiones por unidad de producto.  La ganadería de carne a nivel mundial, es el Sistema de producción que mayores emisiones de gases de efecto invernadero genera p...
Conference Paper
Full-text available
Grass-legume forage associations are an alternative to address seasonality in feed supply in livestock systems, as they provide benefits in the production of biomass as well as in terms of diet quality and productivity. At the same time, they contribute to achieving sustainability of livestock production in the American tropics and thus play an imp...

The potential of forages in improving the social, economic and environmental sustainability of smallholder production systems in the tropics is well recognized. •The Tropical Forages Program of the International Center for Tropical Agriculture (CIAT) has been working for decades on the selection and breeding of forage germplasm, with the aim of exp...

Biological Nitrification Inhibition (BNI) by the tropical pasture grass Brachiaria humidicola (Bh) suppresses the microbial conversion of relatively immobile ammonium (NH + 4) to very mobile nitrate (NO 3) in soils. BNI is expected to reduce nitrogen (N) losses by NO 3 leaching and nitrous oxide (N 2 O) emission. Smallholder farmers could benefit f...
