本研究比较了8个品种的牛不同的性别（小母牛，公牛和阉牛），以确定肌肉特性和肉的感官品质的胸最长肌之间的关联。动物类型在所有的肌肉特征和感官品质上都不同。大多数动物类型的肌肉特性和感官品质之间的许多相关性是一致的。异柠檬酸脱氢酶（ICDH）的活动允许歧视的肌肉肌球蛋白重链（MyHC）-I的比例为所有动物类型。乳酸脱氢酶（LDH）和磷酸果糖激酶（PFK）的活动呈正相关的大多数动物类型。总体喜好与牛肉风味和异常风味的所有动物类型和全球招标的所有动物类型，除了夏洛来杂交种牛。对于所有的动物类型，除了安格斯黑白花小母牛，牛肉风味和异常风味呈负相关。总体而言，喜欢与多汁性无关。PFK，ICDH和柠檬酸合酶（CS）的活动与嫩度，牛肉风味和整体喜好时，所有动物类型的平均值。然而，肌肉特性和感官品质之间的关联在动物类型是弱和不一致的。
The present study compared eight breeds of cattle differing in gender (heifers, bulls and steers) to determine associations between muscle characteristics and meat sensory qualities of the Longissimus thoracis muscle. Animal types differed in all the muscle characteristics and sensory qualities. Many correlations among muscle characteristics and among sensory qualities were consistent for most animal types. Isocitrate dehydrogenase (ICDH) activities allowed discrimination of muscles with respect to myosin heavy chain (MyHC)-I proportions for all animal types. Lactate dehydrogenase (LDH) and phosphofructokinase (PFK) activities were positively correlated for most animal types. Overall liking was correlated with beef flavour and abnormal flavour in all animal types and with global tenderness for all animal types except for Charolais cross breed steers. For all animal types except for AngusxFriesian heifers, beef flavour and abnormal flavour were negatively correlated. Overall liking was not correlated with juiciness. PFK, ICDH and citrate synthase (CS) activities were strongly associated with tenderness, beef flavour and overall liking when average values for all animal types were used. However, associations between muscle characteristics and sensory qualities within animal types were weak and inconsistent.
