Sistema de apoyo a la toma de decisiones para la selección de especies forrajeras (STDF) en función de la oferta ambiental en Colombia

Abstract: <p>La baja oferta de alimento, problema que aqueja a un alto porcentaje de la población ganadera de Colombia, se asocia,en gran medida, a la selección equivocada de especies forrajeras; es decir, con frecuencia las especies sembradas no están adaptadas a la oferta mbiental de una región en particular. Para atenuar el riesgo de la baja oferta forrajera, sin incurrir en costos asociados al cambio de la oferta ambiental, es preciso aprovechar las habilidades fisiológicas de las especies para hacer frente al… Show more

“…Em geral, a produção de metano em termos de CH4 (mL/dia), CH4 (mL/g DMi), CH4 (mL/g DMd) e CH4 (mL/gOMd) reduziu (p<0,05) no CL em relação ao COL. One of the main limitations in this transition is related to animal feeding, given that production relies on grass monoculture (Mojica et al, 2017) characterized by low forage production, availability, and nutritional quality; mainly during dry seasons. It poorly adjusts to the nutritional requirements of cattle, thus affecting productivity and profitability of the production systems (Murillo et al, 2014;Arce et al, 2013). The low nutritional quality and digestibility of forages, given their high content of structural carbohydrates and low protein proportion, increases ruminal methane (CH4) emissions (Archimède et al, 2011).…”

“…El uso y localización de diferentes especies forrajeras debería basarse en el concepto de adaptación fisiológica y/o morfológica. Lo ideal es seleccionar las especies forrajeras según su capacidad de sobrevivir a eventos de déficit o exceso de factores ambientales como el recurso hídrico (Arce et al, 2013).…”
