| 摘 要： | 试验选用 40头 2 8日龄断奶仔猪 ,随机分为 5组 ,分别饲喂添加不同锌水平的日粮 ( 80 ,2 4 0 ,1 0 0 0 ,30 0 0 ,5 0 0 0mg/kg) ,研究日粮添加不同水平锌对断奶仔猪机体组织锌沉积的影响。结果表明 :高锌添加使肝脏、肾脏、趾骨、血清、毛发及粪锌含量极显著上升 (P <0 .0 1 ) ,而背最长肌、扁桃体和胸腺锌含量则只有在添加 5 0 0 0mg/kg日粮锌时含量显著上升 (P <0 .0 5 ) ,脾脏锌含量则随着高锌的添加变化差异不显著P >0 .0 5 ) ;低锌添加 ( 80mg/kg和 2 4 0mg/kg)对机体各组织及粪锌含量无显著影响 (P >0 .0 5 )。

| Abstract: | crossbred weanling pigs (YN 1,n=40, 28-day-old) were used in a 5-weeks trial to determine the effects of dietary zinc (80,240,1000,3000 and 5000 mg/kg) on tissue zinc sedimentation.The results showed that adding high zinc increased liver,kidney, metatarsal bone,serum,hair and excrement zinc concentrations (P<0.01),and only 5000 mg/kg zinc could increase back muscle,tonsil and thymus zinc concentrations(P<0.05),but zinc concentration in spleen had not significantl variation(P>0.05).Low zinc(80 mg/kg and 240 mg/kg)did not influence zinc content in different tissues and excrement(P>0.05). |
