The blood glutathione peroxidase levels of one day old piglets from 22 litters were examined. Body weight and piglet survival were monitored in order to assess the relationship between these two factors and blood glutathione peroxidase activity. The mean blood glutathione peroxidase level of one day old piglets (65 mu/gHb) was significantly lower (p0.001) than the mean level (85 mu/gHb) at weaning. The mean blood glutathione peroxidase activity of one day old piglets was not related to the size of the litter, but was related (p less than 0.1) to the mean litter blood glutathione peroxidase level at weaning time. Piglet blood glutathione peroxidase was not related to piglet body weight. The blood glutathione peroxidase level of the sows at one-day post-farrowing was not related to the mean blood glutathione peroxidase activity of their litters at one day of age but was correlated (p less than 0.1) with the mean blood glutathione peroxidase levels of their litters at weaning. Piglet viability was shown to be strongly correlated (p less than 0.001) with body weight at one day of age. The blood glutathione peroxidase level of one day old piglets was weakly associated (p less than 0.1) with piglet survival. Further work is required to clarify this latter observation, which suggests that selenium supplementation to newborn piglets may be beneficial regardless of the dams nutritional status.
对来自22窝的1日龄仔猪的血液谷胱甘肽过氧化物酶水平进行了检测。监测仔猪体重和存活情况，以评估这两个因素与血液谷胱甘肽过氧化物酶活性之间的关系。1日龄仔猪的平均血液谷胱甘肽过氧化物酶水平（65μ/gHb）显著低于断奶时的平均水平（85μ/gHb）（p<0.001）。1日龄仔猪的平均血液谷胱甘肽过氧化物酶活性与窝产仔数无关，但与断奶时窝平均血液谷胱甘肽过氧化物酶水平相关（p<0.1）。仔猪血液谷胱甘肽过氧化物酶与仔猪体重无关。分娩后1天母猪的血液谷胱甘肽过氧化物酶水平与其1日龄仔猪窝的平均血液谷胱甘肽过氧化物酶活性无关，但与断奶时仔猪窝的平均血液谷胱甘肽过氧化物酶水平相关（p<0.1）。仔猪活力与1日龄时的体重密切相关（p<0.001）。1日龄仔猪的血液谷胱甘肽过氧化物酶水平与仔猪存活率弱相关（p<0.1）。需要进一步开展工作以阐明后一项观察结果，这表明无论母猪营养状况如何，给新生仔猪补充硒可能有益。
