Summary, etc |
Cuando se compara el comportamiento de un gran no. de cv. de especies forrajeras en un programa rutinario de evaluacion, no resulta practico utilizar al animal de pastoreo para simular las condiciones de pastoreo. Se utilizan por lo tanto sistemas de corte. Con el objeto de evaluar la validez de esta practica se realizaron experimentos de campo en 2 localidades durante 2 estaciones para comparar los rendimientos de forraje de 6 var. de Lolium perenne bajo un manejo estandar de corte, con los rendimientos de las mismas durante un manejo de pastoreo. En una de las localidades se usaron ovinos y en la otra bovinos. En la primera estacion de cosecha el orden de clasificacion de las var. fue similar bajo el manejo de corte y el de pastoreo tanto con los ovinos como con los bovinos. Generalmente los rendimientos fueron mayores bajo el manejo de corte pero el rango entre la var. de mas alto rendimiento y la var. de rendimiento mas bajo fue mayor bajo el manejo de pastoreo. En la segunda estacion de cosecha el orden de clasificacion de las var. fue nuevamente similar en general para ambos tipos de manejo tanto en el experimento con ovejas como con bovinos, pero hubo una excepcion.
