This study used 300 1-day-old, sexless, developing chicks of Japanese quail to estimate the ability of vitamin C and/or garlic to antagonize the venomous influence of cadmium (Cd) on the hematological, immunological, and performance characteristics of developing Japanese quail. The quail was separated into 5 similar groups of 60 chicks apiece, and 6 duplicates (10 each) were given to each sub-group. The control group received a basal diet without any supplements. The Cd group was nourished with a basal diet of + 80 mg cadmium chloride (CdCl)/kg diet. The 3rd group was fed a basal diet + 80 mg CdCl2/kg diet and complemented with a 200 mg Vitamin C (Cd + C)/kg diet. The 4th group was nourished with a basal diet + 80 mg CdCl/kg diet and complemented by a 500 mg dried garlic powder (Cd + G)/kg diet. The 5th group was fed a basal diet + 80 mg CdCl/kg diet, complemented by a 200 mg vitamin C/kg diet + 500 mg dried garlic powder (Cd + CG)/kg diet. Results showed that in the 5th group in which cadmium was added together with Vit C + garlic, there was an improvement in both live weight gain (1-42 d) and feed consumption (1-21 and 1-42 d ) compared to the group in which Cd was added alone. The addition of Vit C alone and together with garlic seems to completely improve the cadmium-related increase in alkaline phosphatase (ALP), and Aspartate aminotransferase (AST), and Malondialdehyde (MDA) levels when compared to the control. Compared to cadmium-polluted diets, quail that got cadmium and feed additives significantly reduced cadmium residue. In addition, the cadmium group's serum immunoglobulin M (IgM) level decreased significantly. These data imply that dietary supplementation with (C) or (G) may be beneficial in retrogressing the drop in immunoglobulin G (IgG) and IgM caused by Cd and minimizing Cd's deleterious influence on immunity.
本研究使用 300 只 1 日龄、无性别、发育中的鹌鹑来估计维生素 C 和/或大蒜对镉(Cd)毒性对发育中鹌鹑的血液学、免疫学和性能特征的拮抗作用。将鹌鹑分为 5 组,每组 60 只,每组 6 个重复(每个重复 10 只)。对照组接受不含任何补充剂的基础饮食。Cd 组用基础饮食+80mg 氯化镉(CdCl)/kg 日粮喂养。第 3 组用基础饮食+80mg CdCl2/kg 日粮喂养,并补充 200mg 维生素 C(Cd+C)/kg 日粮。第 4 组用基础饮食+80mg CdCl/kg 日粮喂养,并补充 500mg 干大蒜粉(Cd+G)/kg 日粮。第 5 组用基础饮食+80mg CdCl/kg 日粮喂养,补充 200mg 维生素 C/kg 日粮+500mg 干大蒜粉(Cd+CG)/kg 日粮。结果表明,在添加 Vit C+大蒜的第 5 组中,与单独添加 Cd 的组相比,活体重增加(1-42 天)和饲料消耗(1-21 天和 1-42 天)均有所改善。单独添加 Vit C 以及与大蒜一起添加似乎完全改善了与镉相关的碱性磷酸酶(ALP)、天门冬氨酸氨基转移酶(AST)和丙二醛(MDA)水平的升高,与对照组相比。与镉污染饲料相比,摄入镉和饲料添加剂的鹌鹑显著降低了镉残留。此外,镉组的血清免疫球蛋白 M(IgM)水平显著降低。这些数据表明,膳食补充(C)或(G)可能有助于逆转 Cd 引起的免疫球蛋白 G(IgG)和 IgM 下降,并最大程度地减少 Cd 对免疫的有害影响。
