Producción bovina bajo manejo silvopastoril intensivo a escala de establecimiento y ciclo completo en Tierra del Fuego, Argentina

Abstract

Los sistemas bovinos extensivos de Tierra del Fuego incorporan escasa tecnología de manejo por lo que poseen bajos niveles de producción por unidad de superficie. No obstante, hoy existen tecnologías disponibles como la evaluación de pastizales, la separación de ambientes y el pastoreo rotativo que permitirían un mejor manejo del pastoreo. En el presente estudio se ha puesto a prueba una propuesta de manejo que incorpora estas tecnologías, evaluando diversos indicadores (porcentaje de preñez y destete, evolución de peso, hábitos dietarios, comportamiento animal, incidencia de parásitos, compactación de suelos y cambios en la composición botánica del pastizal) a escala de establecimiento y ciclo completo. Los resultados han mostrado la viabilidad de la propuesta de manejo y sus ventajas: Preñez: 94,4%, Destete: 93,1%, Producción de carne: hasta 1,22 Kg/animal/día y 73 Kg/ha, y mayor mansedumbre del ganado. No obstante, se advierte la importancia de monitorear constantemente la evolución de los pastizales a fin de lograr un uso sustentable del recurso pastoril.

The extensive bovine systems of Tierra del Fuego incorporate little management technology so they have low production levels per unit area. However, there are technologies available such as grassland assessment, vegetation type separation, and rotational grazing system that would allow better grazing management. In the present study, a management proposal that incorporates these technologies has been tested by evaluating various indicators (percentage of pregnancy and weaning, weight development, dietary habits, animal habits, parasite incidence, soil compaction and changes in composition botany of the pasture) at ranch level and complete production cycle. The results shown the viability of the proposed intensive management and its advantages: Pregnancy: 94.4%, Weaning: 93.1%, Meat production: up to 1.22 kg/animal/day and 73 kg/ha, and better tameness of cattle. However, monitoring the evolution of grasslands in order to achieve a sustainable use of the pastoral resource is needed.
