Differing conditions in captive breeding and in the wild have impact on the mineral profile of the pheasant carcass and its heavy metal contents. This may be an indicator of environmental contamination. The study evaluated the nutritional composition and selected macro- and trace element contents (heavy metals in particular) in usable sections of pheasant breast and thigh muscles originating from captive breeding and wild birds.
The tests were performed on the breast and thigh muscles of 20 wild and 20 farm bred birds from around Lublin, Poland, with equal sex representation. The nutrient and lead, cadmium, chromium, and nickel contents were determined using inductively-coupled plasma atomic emission spectroscopy.
The farmed pheasants had a higher proportion of breast muscle. The thigh muscles of all birds had a higher fat content than the breast muscles (5.1 g . 3.4 g per kg of natural weight). The macroelement level depended on the muscle type and bird origin. The trace element content also did and gender dependence was also evident. The wild birds contained more cadmium in the breast muscles and lead in both muscles than the farm-raised ones.
The high quality and usefulness of wild and farmed pheasant meat is confirmed. It has advantageous macro- and trace element contents and permissible heavy metal contents except for lead in wild birds. The heavy metal level can be a bioindicator of their environmental occurrence. In wild birds, the lead level may also reflect birdshot remnants.
圈养繁殖和野生环境中的不同条件会对雉鸡胴体的矿物质分布及其重金属含量产生影响。这可能是环境污染的一个指标。本研究评估了来自圈养繁殖鸟类和野生鸟类的雉鸡胸肌和大腿肌肉可用部分的营养成分以及选定的常量和微量元素含量(特别是重金属)。
对来自波兰卢布林周边地区的20只野生鸟类和20只养殖鸟类的胸肌和大腿肌肉进行了测试,雌雄比例相同。使用电感耦合等离子体原子发射光谱法测定营养成分以及铅、镉、铬和镍的含量。
养殖雉鸡的胸肌比例更高。所有鸟类的大腿肌肉脂肪含量均高于胸肌(每千克自然重量中,大腿肌肉含脂肪5.1克,胸肌含脂肪3.4克)。常量元素水平取决于肌肉类型和鸟类来源。微量元素含量也是如此,性别依赖性也很明显。野生鸟类胸肌中的镉含量以及两种肌肉中的铅含量均高于养殖鸟类。
野生和养殖雉鸡肉的高品质和可用性得到了证实。其常量和微量元素含量具有优势,野生鸟类除铅外的重金属含量也在允许范围内。重金属水平可以作为它们在环境中存在情况的生物指标。在野生鸟类中,铅含量也可能反映霰弹残留情况。
