The current study aimed to investigate the effects of pomegranate peel and olive pomace supplementation on the reproductive hormones, antioxidative status, reproductive capacity and maternal behaviour of rabbit does. Forty does were used for the experiments. The animals were randomly assigned to four groups of ten does. One group was fed on the control diet and was considered the control group (C). The second group was supplemented with 4.5% pomegranate peel in their diet (P), the third group was supplemented with 10% olive pomace in their diet (O), and the fourth group was supplemented with a mixture of pomegranate peel and olive pomace (PO). Compared with the control does, group P showed significantly increased serum levels of gonadotropic hormones and oestradiol-17β two hours after mating, on the 20th day of lactation and after weaning; significantly increased progesterone levels at mid-pregnancy; and significantly increased in prolactin levels on the 10th day of lactation. Additionally, the results revealed significant increases in total DNA, protein concentration, litter size, milk yield and nest traits of groups P and PO. In conclusion, pomegranate peel supplementation improves the reproductive performance of does and increases their antioxidant parameters.

石榴皮和橄榄渣补充对兔母兔繁殖和氧化状态的影响

本研究旨在探讨石榴皮和橄榄渣补充剂对兔的生殖激素、抗氧化状态、生殖能力和母性行为的影响。实验使用了四十个。这些动物被随机分配到四组，每组十只。一组以对照饮食喂养并被认为是对照组（C）。第二组在他们的饮食中添加了 4.5% 的石榴皮（P），第三组在他们的饮食中添加了 10% 的橄榄渣（O），第四组在他们的饮食中添加了石榴皮和橄榄渣的混合物。宝）。与对照组相比，P组在交配后2小时、哺乳第20天和断奶后血清促性腺激素和雌二醇17β水平显着升高；孕中期孕酮水平显着升高；并在哺乳第 10 天显着增加催乳素水平。此外，结果显示 P 组和 PO 组的总 DNA、蛋白质浓度、窝产仔数、产奶量和巢穴性状显着增加。总之，石榴皮补充剂改善了雌激素的繁殖性能并增加了它们的抗氧化参数。
