Abstract The present study evaluates the effects of natural extracts on reproductive performance, haematochemical parameters, and antioxidant status of rabbit does. A total of sixty New Zealand White second parity does were divided into three groups: the first group was fed a control diet (CON), the second (T1) and the third groups (T2) were fed the same diet supplemented with prebiotic polysaccharides from brown seaweeds (Laminaria spp.) plus phenolic acid, hydroxycinnamic acids, tannins, and flavonoids from plant extracts (0.3% and 0.6%, respectively). The trial was conducted for two consecutive reproductive cycles (75 days). Reproductive performance was recorded. Blood samples were collected before the first insemination, 10 d after the first kindling, and 10 d after the second one. At the first reproductive cycle, productive parameters were negatively affected (P<0.05) by a high dosage of the dietary supplement (T2 group). At the second reproductive cycle, no differences (P>0.05) between dietary treatments on reproductive and productive performances were observed. Bilirubin was affected by dietary treatment (P<0.001) and decreased in relation to sampling time (P<0.001). The HDL cholesterol decreased by dietary treatment (P<0.01). All the plasma antioxidant markers were positively affected (P<0.001) by dietary supplementation and sampling time. No previous study has reported the effects of brown seaweeds and polyphenols on rabbit does and the present data shows that this natural extract supplement improved the antioxidant status of rabbit does.

天然提取物混合物的膳食补充剂:对兔繁殖性能、血液生化和抗氧化参数的影响

摘要 本研究评估了天然提取物对兔子生殖性能、血液化学参数和抗氧化状态的影响。总共 60 只新西兰白二胎被分成三组:第一组喂食对照日粮 (CON),第二组 (T1) 和第三组 (T2) 喂食相同的日粮,辅以益生元多糖棕色海藻(Laminaria spp.)加上植物提取物中的酚酸、羟基肉桂酸、单宁和黄酮类化合物(分别为 0.3% 和 0.6%)。试验进行了两个连续的生殖周期(75 天)。记录生殖性能。第一次授精前、第一次引种后10 d和第二次授精后10 d采集血样。在第一个生殖周期,生产参数受到高剂量膳食补充剂(T2 组)的负面影响(P<0.05)。在第二个繁殖周期,没有观察到日粮处理对繁殖和生产性能的差异(P>0.05)。胆红素受饮食处理的影响 (P<0.001) 并随采样时间降低 (P<0.001)。高密度脂蛋白胆固醇通过饮食处理降低(P<0.01)。所有血浆抗氧化标志物都受到膳食补充剂和采样时间的积极影响(P<0.001)。以前没有研究报告过棕色海藻和多酚对兔子的影响,目前的数据表明,这种天然提取物补充剂改善了兔子的抗氧化状态。在第二个繁殖周期,没有观察到日粮处理对繁殖和生产性能的差异(P>0.05)。胆红素受饮食处理的影响 (P<0.001) 并随采样时间降低 (P<0.001)。高密度脂蛋白胆固醇通过饮食处理降低(P<0.01)。所有血浆抗氧化标志物都受到膳食补充剂和采样时间的积极影响(P<0.001)。以前没有研究报告过棕色海藻和多酚对兔子的影响,目前的数据表明,这种天然提取物补充剂改善了兔子的抗氧化状态。在第二个繁殖周期,没有观察到日粮处理对繁殖和生产性能的差异(P>0.05)。胆红素受饮食处理的影响 (P<0.001) 并随采样时间降低 (P<0.001)。高密度脂蛋白胆固醇通过饮食处理降低(P<0.01)。所有血浆抗氧化标志物都受到膳食补充剂和采样时间的积极影响(P<0.001)。以前没有研究报告过棕色海藻和多酚对兔子的影响,目前的数据表明,这种天然提取物补充剂改善了兔子的抗氧化状态。001) 并随采样时间降低 (P<0.001)。高密度脂蛋白胆固醇通过饮食处理降低(P<0.01)。所有血浆抗氧化标志物都受到膳食补充剂和采样时间的积极影响(P<0.001)。以前没有研究报告过棕色海藻和多酚对兔子的影响,目前的数据表明,这种天然提取物补充剂改善了兔子的抗氧化状态。001) 并随采样时间降低 (P<0.001)。高密度脂蛋白胆固醇通过饮食处理降低(P<0.01)。所有血浆抗氧化标志物都受到膳食补充剂和采样时间的积极影响(P<0.001)。以前没有研究报告过棕色海藻和多酚对兔子的影响,目前的数据表明,这种天然提取物补充剂改善了兔子的抗氧化状态。
