INTRODUCTION• In 2006, Colombia launched its Strategic Plan for Livestock Production     (PEGA 2019) aiming at a reduction of the total area under pasture by 10    million ha until 2019• To achieve this goal, the current production systems, characterized by     strong seasonality and a low offer in feed quality and quantity, need to be     transformed into more sustainable production systems with higher animal    productivity and resilience to changing environmental conditions • Improved forages such as grasses and (herbaceous and shrub) legumes     are viable alternatives for livestock systems in adverse environmental    conditions (e.g., extreme droughts or floodings, high aluminium saturation     in soils) contributing to higher animal productivity, feed availability and    environmental sustainabilityOBJECTIVESMeasuring animal live weight gains in grass-legume forage associations with the aim to:• Identify the forage effect on the     animal, expressed in animal    productivity per unit area• Validate the persistence of    (herbaceous and shrub)    legumes under grazingby Neil Palmer (CIAT)0100200300400500600700800(T1) Toledo (T2) Toledo + Canavalia (T3) Toledo + Canavalia +LeucaenaLive Weight Gain (kg/year)0501001502002503003504000 38 71 116 148 184 207 235 267 331 361DaysChanges in animal live weight during 1 yearToledo Toledo + Canavalia Toledo+Canavalia+LeucaenaRESULTS• Animals grazing Brachiaria brizantha cv. Toledo associated with the     legume Canavalia brasiliensis (T2) showed the highest individual     daily weight gains: 380 g, 125 g more than those grazing Brachiaria     brizantha cv. Toledo only (T1)• Animals grazing grass-legume associations (T2 and T3) show    higher per area live weight gains (554 and 526 kg/year) than those     grazing Brachiaria brizantha cv. Toledo only (T1; 371 kg/year) • The higher per area productivity of grass-legume associations is    related to both forage quantity and qualityACKNOWLEDGEMENTSThis work was done as part of the CGIAR Research Program on Livestock and Fish This work was undertaken as part of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), which is a strategic partnership of CGIAR and Future EarthWe thank all donors that globally support our work through their contributions to the CGIAR systemREFERENCESFedegan (2006).
