Studies were carried out to establish the relationship between the biogeochemical characteristic of the subregions and the level of the basic trace and macroelements with the Camborough pig hybrid. Blood samples were taken from 380 pigs at five complexes located in various regions of the country, and the quantitative values were fixed of Zn, Fe, Cu, K, and Na. The correlation was proven between the geographic location of the complexes and the aspects of the technologic regimes, on the one hand, and the levels of the micro- and macro-element studied, on the other. Determined were also the dependable intervals for iron, zinc, copper, potassium, and sodium, and the physiologic parameters of the same elements were found in the conditions of the swine-breeding complexes.
开展了多项研究，以确定次区域的生物地球化学特征与坎伯勒杂交猪体内基本微量元素和常量元素水平之间的关系。从位于该国不同地区的五个养殖场的380头猪身上采集了血样，并测定了锌、铁、铜、钾和钠的含量。一方面，证明了养殖场的地理位置与技术管理制度之间存在相关性；另一方面，也证明了与所研究的微量元素和常量元素水平之间存在相关性。还确定了铁、锌、铜、钾和钠的可靠区间，并在养猪场条件下发现了这些元素的生理参数。
