摘要 比较研究在相同的饲养管理条件下,孕期补硒对不同品种绵羊血清中硒(Se)、铜(Cu)、锌(Zn)含量的影响。以处于怀孕期的85只蒙古羊、道赛特羊和萨福克羊为研究对象,通过荧光分光光度法测定Se含量、原子吸收法测定Cu、Zn含量。结果显示,补Se各品种羊从怀孕3个月起血清Se含量显著高于未补硒同品种羊(P<0.05),补Se与未补Se同品种羊血清Zn含量在各期差异不显著(P>0.05),补Se与未补Se蒙古羊血清Cu含量各期差异不显著(P>0.05)。结果表明,Se与Cu、Zn不具有颉颃作用,说明补Se对母体维持正常妊娠和增强抗病性功能具有重要作用。 Studies on effects of selenium, copper, zinc in serum of different kinds of sheep in pregnancy which were added selenium in the identical condition of feeding management. There were 85 sheep in pregnancy including Mongolian sheep,Dorset and Suffolk sheep, determined contents of selenium by fluorescence spectrophotometry method, determined contents of copper and zinc by atomic absorption spectrophotometry method. Results showed that from pregnant 3 months on, the content of selenium in serum of each kind sheep which was added selenium was significantly higher than that of the same kind sheep which was non-added selenium, and at the same time, the content of zinc in serum was non-significantly (P〉0.05) between the same kind of sheep which were added selenium and non-added selenium,and the content of copper in serum was non-significantly (P 〉0.05) between added selenium and non-added selenium Mongolian sheep. Results indicated that there was no antagonism between selenium and copper or selenium and zinc,so added selenium could play an important role to maintain natural pregnancy and to enhance resistibility.
