| description | The improvement in grazing spatial distribution is an important goal for the efficient and sustainable management of rangelands. However, extensive livestock systems such as the Patagonian rangelands generally fails due to the large paddock size (up to 6000 ha). The purpose of this study was to evaluate the effectiveness of the strategic use of nutritional blocks as an atractive element in underused areas of the landscape, in a shrub steppe of low cover (less than 50%) under dry climate. The spatial distribution of sheep was evaluated in two extensive paddocks (1900 and 5500 ha) under two sequential treatments (With nutritional blocks and Traditional management without nutritional blocks) in two years. The study was carried out using wethers of the Corriedale breed, with an average stocking rate of 0.17±0.03 sheep/ha. The geotracking of wethers was obtained by means of collars equipped with global positioning system technology, configured with a measuring frequency of 5 minutes within an average period of 15 days. The use of nutritional blocks resulted in a 46.1-57.4% expansion in the daily home range with respect to the traditional management, suggesting a more spatial homogeneous use of the paddocks by sheep. These results would have important practical implications, considering that the use of nutritional blocks would allow the combination of supplementation strategies with the sustainable use of pastoral resources. |

El uso de bloques nutricionales como herramienta para el manejo del pastoreo en sistemas ovinos extensivos. Mejorar la distribución espacial del pastoreo es importante para lograr el objetivo de un uso eficiente y sustentable de los pastizales naturales. Sin embargo, los sistemas ganaderos extensivos como los que se utilizan en pastizales de la Patagonia generalmente fallan debido a la gran extensión de los cuadros de pastoreo (hasta 6000 ha). El objetivo del presente estudio fue evaluar la efectividad del uso estratégico de bloques nutricionales como elementos atractivos en áreas subutilizadas del paisaje; específicamente, en una estepa arbustiva de baja cobertura (menos de 50%), bajo un clima árido. La distribución espacial de ovinos fue evaluada en dos cuadros de pastoreo extensivo (1900 y 5500 ha) a través de dos tratamientos secuenciales (Con bloques nutricionales y Manejo tradicional sin bloques nutricionales), en dos años. Para el estudio se emplearon capones (carneros castrados) de la raza Corriedale, bajo una carga animal promedio de 0.17±0.03 ovinos/ha. La geolocalización de los capones se obtuvo mediante collares equipados con sistemas de posicionamiento global, configurados con una frecuencia de medición de 5 minutos en un período de 15 días. El uso de bloques nutricionales resultó en una expansión de 46.1-57.4% del área diaria de campeo con respecto al manejo tradicional, lo que sugiere que los ovinos hicieron un uso espacial más homogéneo de los cuadros. Estos resultados podrían tener importantes implicancias prácticas, considerando que utilizar bloques nutricionales permitiría combinar estrategias de suplementación con el uso sustentable de los recursos pastoriles.
