Meat is an important source of animal protein but, at the same time, it includes saturated fatty acids, which makes it a potential cause of different cardiovascular diseases and still little is known about influence of age and sex on these parameters in roe deer muscles. The aim of this study was to determine the effect of age and sex on the CLA and other fatty acids content in the musculus longissimus lumborum in 67 roe deer (Capreolus capreolus L.). In the meat from the oldest individuals a higher content of CLA was noted (89.76 [mg/kg]) when compared to the fawns (42 [mg/kg]). In this research meat from roe deer does showed in general a higher percentage proportion of SFAs and MUFAs, but lower of PUFAs, than the meat from bucks. These results may provide an important source of information for consumers of roe deer meat because of differences between CLA and other fatty acids content depending on age and sex of the animals. Meat from roebucks is the most advantageous for dietary purposes.
肉类是动物蛋白的重要来源，但同时它含有饱和脂肪酸，这使其成为引发不同心血管疾病的潜在因素，而且关于年龄和性别对狍子肌肉中这些参数的影响仍知之甚少。本研究的目的是确定年龄和性别对67只狍（Capreolus capreolus L.）腰大肌中CLA及其他脂肪酸含量的影响。与幼鹿（42 [mg/kg]）相比，在最年长个体的肉中CLA含量更高（89.76 [mg/kg]）。在本研究中，狍雌鹿的肉总体上显示出比雄鹿的肉含有更高比例的饱和脂肪酸和单不饱和脂肪酸，但多不饱和脂肪酸比例更低。由于CLA和其他脂肪酸含量因动物的年龄和性别而异，这些结果可能为狍肉消费者提供重要的信息来源。雄狍的肉在饮食方面最具优势。
