A substantial proportion of beef production in Colombia originates in its extensive
Eastern Plains. However, in this scenario and in a global context, demand for cattle
production increasingly requests that it satisfies social and environmental expectations
in addition to being economically efficient. A dataset containing five-year long records
of cow-calf production systems collected at Carimagua Research Centre located in the
Meta Department was retrospectively interrogated to understand the liveweight (LW)-
derived flux matrix dynamics of methane (CH4) emissions. Estimated total CH4 (kg)
emissions during the gestation period, were similar between conventional weaned (CW;
37.86 ± 0.506 kg) and early weaned (EW; 37.47 ± 0.476 kg) cows. However, averaged
over two lactations, total CH4 emissions were larger (p < 0.0001) in CW cows (38.67
± 0.456 kg) than in their EW (14.40 ± 0.435 kg) counterparts. Total gas emissions
from birth to comparable commercial yearlings age were higher (p < 0.0001) for CW
(43.11 ± 0.498 kg) calves than for EW (40.27 ± 0.472 kg) calves. It was concluded that
mid and long-term pastoral datasets and new concerns are well suited to understand
different contexts and adaptations to the contemporary weather conditions. Nevertheless,
conventional farming systems will be less environmentally vulnerable if EW
management practices involve the strategic and temporal use of improved pastures. The
roles of veterinary medicine and animal sciences are briefly discussed in the context of
unprecedented climate variability to provide a guide to the uncertain future.

Una proporción substancial de la producción de carne de res en Colombia se origina
en sus Llanos Orientales. Sin embargo, allí, así como en un contexto global, dicha producción
ganadera debe ser económicamente eficiente y satisfacer expectativas sociales y ambientales. Considerando algunos de esos intereses, se analizaron cinco años de eventos productivos y de manejo del destete implementados en el Centro de Investigaciones Carimagua, localizado en el departamento del Meta, para interpretar en vacas de carne y sus crías las dinámicas de peso vivo asociadas con emisiones derivadas de metano (CH4). Emisiones totales de CH4 (kg) durante la gestación fueron similares entre las vacas destetadas convencionalmente (CW; 37.86 ± 0.506 kg) y aquellas  estetadas tempranamente (EW; 37.47 ± 0.476 kg). Sin embargo, el promedio de dos lactancias demostró mayores (p < 0.0001) emisiones en vacas CW (38.67 ± 0.456 kg) que en vacas EW (14.40 ± 0.435 kg). Emisiones acumuladas entre el nacimiento y el levante fueron mayores (p < 0.0001) en terneros CW (43.11 ± 0.498 kg) que en terneros EW (40.27 ± 0.472 kg). Se concluyó que nuevos cuestionamientos y datos de pastoreo de mediano y largo plazo son apropiados para entender contextos innovadores y adaptaciones a las condiciones climáticas actuales. Sin embargo, el manejo onvencional en las fincas será menos vulnerable al medio ambiente si prácticas de destete temprano son introducidas considerando el uso estratégico y temporal de pastos mejorados. Los roles de la medicina veterinaria y las ciencias animales se discuten brevemente en el contexto de la variabilidad climática existente.
