摘　　要：选用１０２６只１周龄罗斯蛋用雏鸡为试验动物，研究不同日粮Ｓｅ水平对雏鸡组织Ｓｅ含量的影响。结果表明雏鸡的Ｓｅ缺乏或过量均可通过各组织Ｓｅ含量的变化反映出来，但反映的敏感性及临界指示值因组织及发育期不同而异。日粮Ｓｅ水平缺乏或过量时，各组织Ｓｅ含量相应降低或增加。在本试验条件下得出罗斯蛋用雏鸡的Ｓｅ需要量范围为０．１４５×１０￣（－６）～０．４９５×１０￣（－６），其中以０．１９５×１０￣（－６）最佳；日粮Ｓｅ含量≤０．０９５×１０￣（－６）或≥０．９９５×１０￣（－６），雏鸡出现Ｓｅ缺乏症或中毒症。one-week-old Ross egg chicks were used to study the effects of thedifferent dietary selenium content on Se-contents of tissues of chicks. Results showed thatSe-contents of tissues of chicks could reflect selenium deficiency or selenium excess ofchicks, but sensitivity of reflecting them was relating to tissues and the growth period.While dietary selenium content was deficient or excess,selenium content of tissues decreasedor increased significantly. Under condition of the trial, the Se-requirement of ross eggchicks was at 0.145 × 10￣(-6)～0.495 ×10￣(-6),and the best result was obtained from 0.195 ×10￣(-6)group.When dietary Se-content was below 0.095 × 10￣(-6) or above 0.995 × 10￣(-6), Se-deficiency or Se-toxicity disease of chicks appeared.
