During the last third of pregnancy period, rabbits are exposed to many challenges, such as health complications and oxidative stress. The present study aims to use garden cress seeds (GAC) as a natural antioxidant to mitigate these challenges and evaluate its effects on reproductive performance, immunity, hormones, protein profile and milk quality. A total of 24 pregnant V-Line rabbits (pregnant at 20 days proved by palpation), with an initial body weight of 2395.83 g and about 6-7 months of age, were randomly distributed to 4 groups, the control group was fed the basal diet without GAC, the other treated groups GAC 3, GAC 4.5 and GAC 6 were fed the basal diet supplemented with 3, 4.5, and 6% GAC, respectively. The experiment lasted six weeks. The results revealed that treated female rabbits with different levels of GAC did not have a noticeable effect on milk yield, average daily milk yield, or most of the milk analysis parameters (milk density, total solids, solids not fat, lactose, ash, and protein). On the other hand, GAC showed a significant increase in milk fat, and GAC 3% rabbits displayed a higher percentage of milk fat (p < 0.050) than the other groups. Likewise, treatment with GAC also had a significant impact on serum total protein, globulin, IgG, and IgM. The 3% GAC rabbits showed significantly higher total protein, globulin, and IgM values than the control group. However, all GAC treatments significantly improved serum IgG and the best value was found in the 3% GAC group. In conclusion, our results demonstrated that feeding lactating rabbits a diet supplemented with GAC could be considered a good strategy to enhance immunity, protein profile, MY and milk fat. The best results were obtained with the GAC 3% treatment.
在妊娠后期的最后三分之一时间里，兔子会面临许多挑战，如健康并发症和氧化应激。本研究旨在使用荠菜籽（GAC）作为天然抗氧化剂来减轻这些挑战，并评估其对繁殖性能、免疫力、激素、蛋白质谱和牛奶质量的影响。总共 24 只怀孕的 V 型线兔（通过触诊证明在 20 天怀孕），初始体重为 2395.83 克，年龄约为 6-7 个月，被随机分配到 4 组，对照组饲喂基础日粮而不添加 GAC，其他处理组 GAC 3、GAC 4.5 和 GAC 6 则分别在基础日粮中添加 3、4.5 和 6%的 GAC。实验持续了六周。结果表明，不同水平 GAC 处理的雌性兔子对产奶量、日均产奶量或大多数牛奶分析参数（牛奶密度、总固体、非脂固体、乳糖、灰分和蛋白质）没有明显影响。另一方面，GAC 显著增加了牛奶脂肪，而 GAC 3%组的牛奶脂肪百分比高于其他组（p<0.050）。同样，GAC 处理对血清总蛋白、球蛋白、IgG 和 IgM 也有显著影响。GAC 3%组的兔子血清总蛋白、球蛋白和 IgM 值显著高于对照组。然而，所有 GAC 处理都显著提高了血清 IgG，而 3%GAC 组的效果最好。综上所述，我们的结果表明，在泌乳兔日粮中添加 GAC 可以被认为是增强免疫力、蛋白质谱、MY 和牛奶脂肪的一种良好策略。GAC 3%的处理效果最好。
