摘要

与其他狩猎物种和家畜相比,关于非洲热带草原水牛(Syncerus caffer caffer)的产量和肉类的证据不足。我们研究的目的是调查年龄(分类)和性别对水牛胴体产量的影响。为此,屠宰雄性水牛(n = 17)和雌性水牛(n = 13),以及成年水牛(n = 23)和亚成年水牛(n = 7),测定胴体、各器官/内脏和6块主要肌肉(股二头肌(BF)、半膜肌(SM)、半腱肌(ST)、胸腰最长肌(LTL)、冈下肌(IS)和冈上肌(SS))的重量。根据热胴体重计算,水牛的屠宰率较高,其中BF、SM和LTL肌肉重量最重。成年人的肌肉重量比亚成年人重,除了心脏和IS肌肉重量外,所有参数在这些年龄组之间都有显著差异。此外,雄性和雌性之间的皮肤和头部重量差异显著。总之,非洲草原水牛的产量(约58%)优于其他家畜,其宝贵肌肉的重量表明其作为高端增值产品的商业潜力。

Carcass Yields of African Savanna Buffalo (Syncerus caffer caffer)
In contrast to other game species and domestic livestock, there is a paucity of evidence concerning yields and thus meat obtained from the African savanna buffalo (Syncerus caffer caffer ). The aim of our study was to investigate the effects of age (categorized) and sex on buffalo carcass yields. Towards this goal, male (n = 17) and female (n = 13), and adult (n = 23) and subadult (n = 7) buffaloes were slaughtered, and the weight of the carcass and various organs/offal and six major muscles [(biceps femoris (BF), semimembranosus (SM), semitendinosus (ST), longissimus thoracis et lumborum (LTL), infraspinatus (IS) and supraspinatus (SS)] determined. Buffaloes had a high dressing percentage, calculated from the warm carcass weight, and with the heaviest muscle weights measured for the BF, SM and LTL muscles. Adults had heavier muscle weights than subadults, and all parameters except the heart and IS muscle weight differed significantly between these age groups. In addition, the skin and head weight differed significantly between males and females. In summary, African savanna buffalo yields (∼58%) compared favourably to other domestic animals, with the heavy weight of valuable muscles suggesting their commercial potential as a high-end value-added product.
