The aim of the study was to determine the effect of these substitutions on body weight and slaughtering performance, post-mortem changes, sensory characteristics and chemical composition of selected muscle groups of male and female pheasants. The tests were carried out on pheasants during 5–16 weeks of rearing in enclosed aviaries. Four groups of 8 females and 8 males were formed, and the experimental factor was the supplementation of calcium, iron, zinc and copper salts with glycinates of these elements. The control group received a feed blend containing 100% of the mineral requirement as salts. In the E-25 group, 25% of the salts were replaced by glycinates, in the E-50 group 50% of the salts were replaced, and in the E-75 group only glycinates comprising 75% of the total mineral content were used and no salts were included, with vitamin D₃ replaced by calcitriol. For the duration of the study, feeding was at will and the birds had free access to water. In addition, pheasants were weighed at the age of 4, 8, 12 and 16 weeks. Daily feed intake was monitored. At the end of the experiment, when all the pheasants were 16 weeks old, they were weighed and decapitated. The breast, thighs and drumsticks and the heart, liver and gizzard were removed from the chilled carcasses. Supplementation of calcium, iron, zinc and copper salts with 50% glycinates in feed mixtures for pheasants over a period of 5–16 weeks resulted in a slight improvement in the slaughter weight of birds and a significant increase in crude ash, calcium and zinc, while at 75% supplementation and when calcitriol was used instead of vitamin D₃, increased phosphorus levels were found in the pheasant muscles analysed. Males had higher body weight, body weight gain, carcass, liver and gizzard weights, and their muscles had more magnesium and potassium and less calcium, sodium and iron than females.

根据性别对部分无机矿物质用甘氨酸复合物和维生素D3来源部分替代对performance鸡肌肉（Phasianus colchicus L.）的性能，屠宰性状，感觉和理化特性的影响

这项研究的目的是确定这些替代品对雄性和雌性野鸡选定肌肉群的体重和屠宰性能，验尸变化，感觉特征和化学成分的影响。在封闭的鸟笼中饲养的5-16周内对野鸡进行了测试。形成四组，每组8个雌性和8个雄性，实验因素是用这些元素的甘氨酸盐补充钙，铁，锌和铜盐。对照组接受了饲料混合物，其中含有100％的矿物质（盐）。在E-25组中，用甘氨酸盐代替了25％的盐，在E-50组中，用50％的盐代替了，在E-75组中，仅使用了占总矿物质含量75％的甘氨酸盐。不含盐和维生素D₃改为骨化三醇。在研究期间，喂养是随意的，鸟类可以自由饮水。此外，在4、8、12和16周龄时对野鸡进行称重。监测每日采食量。实验结束时，所有野鸡都已出生16周，将它们称重并断头。从冷藏的屠体中取出乳房，大腿和鸡腿以及心脏，肝脏和胃。在野鸡的饲料混合物中添加50％甘氨酸盐的钙，铁，锌和铜盐，在5至16周的时间内，禽的屠宰体重略有改善，并且粗灰，钙和锌的显着增加，而补充量为75％以及使用钙三醇代替维生素D _3时，在分析的山鸡肌肉中发现了较高的磷水平。男性的体重，体重增加，car体重量，肝脏和胃higher重量更高，并且其肌肉中的镁和钾含量更高，而钙，钠和铁含量则低于雌性。
