本研究探讨了铅（LD）对日本鹌鹑生产和繁殖性能的毒性影响以及丝兰提取物（YSE）在减轻这些影响方面的作用。选用2月龄日本鹌鹑360只，试验期8周。试验分为6组：对照组（基础日粮）、基础日粮+ 100 mg LD/kg日粮、基础日粮+ YSE（100 mg/kg日粮）、基础日粮+YSE（200 mg/kg日粮）、基础日粮LD（100 mg/kg日粮）+ YSE（100 mg/kg日粮）和基础日粮+ LD（100 mg/kg日粮）+ YSE（200 mg/kg日粮）。与对照组相比，低剂量组鸡的采食量（FI）、饲料转化率（FCR）和产蛋量均显著下降。在含LD的日粮中添加YSE（100或200）可显著改善鹌鹑的生产性能，使其各项生产性能指标与对照组相当。LD降低了受精率和孵化率，而YSE在两个水平（100或200）单独或与LD组合显示出与对照相当的受精率和孵化率百分比。LD + YSE 100或LD + YSE 200组的甘油三酯、胆固醇和LDL含量均显著低于LD单用组。LD显著降低血清超氧化物歧化酶和过氧化氢酶活性，对还原型谷胱甘肽含量无影响。YSE 100或YSE 200与LD共暴露显著增加了过氧化氢酶活性，并在数值上增加了超氧化物歧化酶活性比单独LD。YSE 100和YSE 200均能降低MDA含量。LD加YSE 100或YSE 200组显示免疫球蛋白水平的显著改善。与LD组相比，YSE与LD联合暴露显著降低了LD在鸡蛋中的残留量。结果表明，YSE对LD诱导的日本鹌鹑生产性能和繁殖性能的抑制作用具有潜在的调节作用，且200 mg/kg剂量的YSE比100 mg/kg剂量的YSE更能有效地逆转LD诱导的这种抑制作用。
The present study investigated the toxic impacts of lead (LD) on the productive and reproductive performances of Japanese quails and the role of Yucca schidigera extract (YSE) in reducing these impacts. A total of 360 mature Japanese quails (at 2 months of age) were used and the experiment was lasted for 8 wk. The birds were divided into 6 equal groups as follows: control (basal diet), basal diet + 100 mg LD/kg diet, basal diet + YSE (100 mg/kg diet), basal diet + YSE (200 mg/kg diet), basal diet LD (100 mg/kg diet) + YSE (100 mg/kg diet), and basal diet + LD (100 mg/kg diet) + YSE (200 mg/kg diet). LD resulted in a significant decrease in feed intake (FI), feed conversion ratio (FCR), and egg production of birds compared with the control group. Supplementation of YSE (100 or 200) to LD containing diet could significantly improve the quail performance parameters to be comparable with the control values. Fertility and hatchability % were decreased by LD, whereas YSE at both levels (100 or 200) separately or in combination with LD showed fertility and hatchability percentages comparable to that of control. Triglycerides, cholesterol, and LDL contents in LD plus YSE100 or LD plus YSE200 groups were significantly decreased than LD alone group. LD significantly decreased superoxide dismutase and catalase activities in the serum with no effect on reduced glutathione content. Co-exposure to YSE100 or YSE200 with LD significantly increased the catalase activity and numerically increased the superoxide dismutase activity than LD alone. YSE100 or YSE200 decreased malondialde-hyde contents than LD alone group. LD plus YSE100 or YSE200 groups exhibited significant improvements in the level of immunoglobulins. Co-exposure to YSE with LD significantly decreased the LD residues in egg than the LD group. The obtained results showed that YSE exhibited a potential modulatory role against the LD-induced inhibitory effects on the productive and reproductive performances of Japanese quails and YSE at 200 mg/kg diet was more effective than 100 mg/kg diet in reversing the LD-induced alterations.
