Abstract
La raza ovina lechera Lacaune, originaria de Francia a partir de la fusión de diferentes razas locales, es la oveja de la leche que se utiliza para la elaboración del queso Roquefort. Esta raza, sometida desde hace más de 30 años a un riguroso esquema de selección genética, se ha convertido en una de las razas ovinas lecheras de mayor rendimiento del mundo, con un promedio de producción de leche acumulada de 283 l en lactaciones medias de 160 días. Desde 1992, 17 países, entre ellos España, han importado de Francia animales seleccionados de raza Lacaune a través de la asociación oficial de criadores. Los sistemas productivos en estos países no enmarcados dentro de la región de Roquefort son muy distintos al manejo tradicional impuesto para la Denominación de Origen (D.O.) de este queso, y sin embargo, la información referente a índices y objetivos en los sistemas productivos de ovejas de raza Lacaune en manejo intensivo es escasa. Si bien, aunque disponemos de algunos datos preliminares respecto a la producción media de esta raza en España, descritos por la cooperativa COVAP, de medias de 405 litros por lactación con lactaciones medias de 175 días de duración, y por la Asociación Española de la Raza Lacaune (AESLA), con datos medios de 304 kg de leche por lactación estandarizada a 160 días de ordeño, carecemos de medidas estandarizadas generales, y de indicaciones de manejo adaptadas a estas ovejas, grandes productoras...
Lacaune sheep originated in France trough the fusion of different regional breeds and produce the milk used to prepare Roquefort cheese. Over the last 30 years, the Lacaune breed was selected from a dual-purpose animal with low dairy yields, to select for an animal with increased milk production. The selection programme has made that this breed becomes one of the world’s highest-yielding ovine milk breeds, with average daily milk yields of 1.59 l and a total milk yield of 283 l over a 160-d lactation period. Since 1992, 17 countries, including Spain, have officially imported dairy Lacaune from France THe production systems for producers outside the Roquefort Designation of Origin are very different to those of this Region, with traditional production conditions, being much more often intensive systems. However, and in contrast to the abundant research on traditional management, information about performance of ovine under intensive management systems is scarce. Some preliminary data of average productivity of this breed under intensive productive conditions in Spain are available with average production per lactation of 405 l/lactation and lactation lengths of 175 days being published by the COVAP producers Association, as well as data of 304kg milk/lactation standardized to 160d long lactations coming from AELSA. However above these data, we have no information about standardized objective index and parameter values, nor management indications adapted to this breed...
