A study on mineral metabolism and conversion of nutrients by applying sodium monensinate, 125 mg per head and day, in cattle fattening was performed. This experiment was realized under production conditions in the fattening station of pavillion type for 367 days and included 985 bulls of Bohemian Spotted cattle. The feed ration consisted of maize silage with addition of dried poultry bedding and concentrates. At the beginning of the experiment the appetite antipathy was observed, the adaptation period lasted 4 weeks. During the adaptation period the weight gains decreased; after adaptation of animals to monensin the weight gain not only counter-poised, but in comparison with the control it increased. Throughout the experiment no health disorders connected with the applied additive were observed. In the rumen fluid the content of calcium, magnesium, phosphorus, zinc, copper and iron was followed. In the blood plasma the levels of sodium, potassium, calcium, magnesium, phosphorus, zinc, copper and iron were followed. The application of sodium monensinate did not affect the followed parameters of mineral metabolism. The experiment was aimed at the evaluation of production and operational parameters with a view to the weight gain and feed conversion. In the experimental group the weight gain was higher by 3.85%. The saving of maize silage in the experimental group amounted to 5.8%, by using of this additive the saving of concentrates amounted to 1.35%. In the experimental group the feed conversion converted to dry matter increased by 7.12%. Sodium monensinate at the dose of 125 mg per head and day had positive effect on the followed production and economic parameters.
进行了一项关于在肉牛育肥中应用莫能菌素钠（每头每天125毫克）对矿物质代谢和养分转化的研究。该实验在亭式育肥站的生产条件下进行了367天，包括985头波希米亚斑点牛公牛。日粮由添加干禽舍垫料的玉米青贮饲料和精饲料组成。实验开始时观察到食欲反感，适应期持续4周。在适应期内体重增加减少；动物适应莫能菌素后，体重增加不仅得到平衡，而且与对照组相比有所增加。在整个实验过程中，未观察到与所应用添加剂相关的健康问题。跟踪瘤胃液中钙、镁、磷、锌、铜和铁的含量。跟踪血浆中钠、钾、钙、镁、磷、锌、铜和铁的水平。莫能菌素钠的应用未影响所跟踪的矿物质代谢参数。该实验旨在评估与体重增加和饲料转化率相关的生产和操作参数。实验组的体重增加高出3.85%。实验组玉米青贮饲料的节省量为5.8%，使用这种添加剂精饲料的节省量为1.35%。实验组转化为干物质的饲料转化率提高了7.12%。每头每天125毫克剂量的莫能菌素钠对所跟踪的生产和经济参数有积极影响。
