摘要

西班牙美利奴是世界上最重要的品种,因为它是所有美利奴和美利奴衍生品种的起源。它的基因改良始于伊比利亚半岛的罗马人,其选择目标很明确:羊毛的细度。然而,在过去的六十年中,西班牙的普遍做法是将该品种的动物与其他肉质更佳的品种杂交,这明显改变了选育标准,导致了大量绵羊的存在。

Situación genética de las principales líneas puras del merino español
The Spanish Merino is the most important worldwide breed due to be the origin of all the Merino and Merino-derived breeds. Its genetic improvement began with the Roman people in the Iberian Peninsula with a clear selection objective: the fineness of the wool. However, in the last six decades, it has been common practice in Spain to cross animals from this breed with other breeds with greater meat aptitude in a clear change of the selection criteria resulting in the existence of a large ovine popula-Anaya
