| 摘 要： | 选择生长发育正常的绿壳蛋鸡15 000只,随机分成笼养高密度组、笼养低密度组和散养组,每组又分为对照组和实验组,2 500只/组。对照组饲喂正常日粮,实验组饲喂添加0.1%的牛磺酸日粮。在实验期第90天,每组随机选取10只采集血液和肾脏,进行肾脏形态和相关生化指标检测。结果显示:饲养方式和日粮中添加0.1%牛磺酸对血清中SCr和UA含量没有显著影响(P0.05);笼养蛋鸡血清BUN含量无论在高密度组还是低密度组均显著高于散养组(P0.05)。iNOs活性、TNF-α、IFN-γ、IL-4和IL-10等和炎症免疫相关的细胞因子水平在各饲养模式及处理间均无显著差异。饲养方式对肾脏组织中MDA含量、SOD和T-AOC活性无显著影响。散养组肾脏T-AOC活性显著高于笼养高密度组(P0.05);日粮中添加0.1%牛磺酸可以显著升高散养组和笼养高密度组肾脏T-AOC活性(P0.05)。结果表明,散养、降低饲养密度和日粮中添加牛磺酸可以提高肾脏组织抗氧化水平,调控机体的代谢,改善饲养应激造成的肾脏组织损伤,进而提高蛋鸡的健康水平。

| Abstract: | 15 000 green-shell laying hens（148 day-old）were randomly assigned into a free range group, and 2 caged groups with low-density and high-density housing, respectively. Each group was further divided into the control（C）and taurine treatment（T） groups. All the test subjects were fed the same basic diet except that the T groups was supplemented with 0.1% taurine. After 90 days, serum, kidneys were aseptically collected. The results show that there was no significant change of serum concentrations of SCr and UA between different groups（P＆gt;0.05）. Compared with free range group, serum BUN concentrations were higher both in high-density group and low-density group（P＆lt;0.05）. No significant difference was observed on iNOs activities and TNF-α, IFN-γ, IL-4, IL-10 concentrations in different groups. There was no significant change of MDA content, SOD and T-AOC activity in kidney tissue under different rearing patterns（P＆gt;0.05）. Compared with high-density group, the T-AOC levels in free range group increased obviously（P＆lt;0.05）. The T-AOC levels of free range group and caged groups with high-density housing with 0.1% taurine increased significantly（P＆lt;0.05）. The data indicate that free range, reduced housing density and taurine could influence anti-oxidation level, regulate metabolism and protect the normal function of the kidney and thus enhance the health of laying hens. |
