Descripción
El proyecto consiste en evaluar cual es el efecto de una mezcla a base de cuatro especies forrajeras: King grass morado, cuba 22, caña de azúcar y botón de oro sobre el consumo voluntario de forraje y la ganancia diaria de peso (GDP) en 12 animales cebú comercial, estos fueron asignados al grupo tratamiento, donde las raciones diarias fueron calculadas con el alimento ofrecido y el restante para medir su consumo. Al grupo control fueron asignados 12 animales donde consumían forraje Brachiaria decumbens en pastoreo rotacional. Se realizo un análisis bromatológico de la mezcla ofrecida al grupo tratamiento y a la pastura Brachiaria decumbens del grupo control. Finalmente, se realizó una evaluación económica de estas prácticas. Los resultados indican que el consumo diario de la mezcla aumento 10 kg de materia verde por animal mensualmente. El efecto sobre las ganancias diarias de peso (kg) mejoró significativamente con la mezcla de los cuatro forrajes (0,680 kg/d) al compararla con el control (0,377 kg/d). Entre las fuentes la más alta ganancia (P
The project evaluates the effect of the mixture based on four forage species: morado King grass, Cuba 22, sugar cane and botón de oro on the voluntary feed intake and daily gain (GDP) in 12 animals: commercial Cebú, they were assigned to a treatment group T1 where the daily rations were calculated with the food offered and the other to measure consumption. The control group was assigned 12 animals which consumed forage Brachiaria decumbens in extensive grazing. One compositional analysis of the mixture featured in T1 and grazing Brachiaria decumbens control group was conducted. Finally, an economic evaluation of these practices was carried out. The results indicate that daily mixture consumption increased to 10 kg of green matter per animal monthly. The effect on daily weight gain (kg) improved significantly with the mixture (0.680 kg/d) when compared to the control (0.377 kg/d). From the sources the highest gain (P
