| Abstract: | The content and seasonal changes of Cu were studied by analyzing the samples from water,soil,edible grass(gained by fistula set on esophagus),wool and other organs such as plasma,liver,skeleton,etc.in sheep from Qinghai province.The results showed that soil Cu content critically lack in summer,autumn and winter;Cu content was higher in edible grass in summer than in autumn while lacks in winter;Cu content was lower than normal level in hair and critical lack in plasma and other organs of sheep;In general,sh... |
