介绍特克塞尔羊被公认为他们的良好构造，肌肉发达和精益。在比利时，Texel绵羊被选择用于肌肉肥大的极端形式，有时被称为“双肌”，与牛的情况类似（Leroy，1989）。虽然这种特征被认为是遗传的，但其确切的遗传方式仍然未知。为了阐明这一性状的遗传，进行了比利时特克塞尔和罗曼诺夫的杂交试验。在这些杂交中测量了大量的胴体性状，以更精确地表征这种绵羊肌肉肥大。
INTRODUCTION Texel sheep are recognized for their good conformation, muscularity and leanness. In Belgium Texel sheep have been selected for an extreme form of muscular hypertrophy sometimes referred to as “double-muscling” by analogy with the bovine condition (Leroy, 1989). While this trait is recognized to be inherited, its precise mode of inheritance remains unknown. In order to clarify the heredity of this trait, a crossbreeding experiment involving Belgian Texel and Romanov was carried out. A large number of carcass traits were measured in these crosses in order to more precisely characterize this ovine muscular hypertrophy.
