This study was aimed to assess the impacts of aloe vera (AV) and clove (Cv) powder supplementation on growth performance, carcass quality, blood biochemistry, and hematology of Japanese quails and studying the possibility of using them as alternatives to antibiotics growth promotors as a natural safe products. Four hundred, 7-d old mixed sex chicks were divided into 4 groups of 5 replicates 20 birds per replicate including (10 males and 10 females). Birds in the control group (T1) were fed a diet containing Enramycin (0.02%) as an antibiotic growth promoter (AGP), while T2, T3 and T4, birds were supplemented with AV leaf powder, Cv powder and mixture of both at 0.5, 0.5 and 0.25 + 0.25% of feed, respectively. Results showed that total feed intake in all supplemented groups were significantly (P < 0.05) higher than T1. Weight gain and feed conversion ratio were significantly higher (P < 0.05) in T4 while T2 and T3 were better (P < 0.05) than T1. Breast yield and carcass weight were the highest (P < 0.05) in T4 while T2 and T3 were significantly better than T1. High density lipoprotein was highest (P < 0.05) in T4 whereas T2 and T3 showed higher value than T1. Blood cholesterol and serum enzymes (ALT, AST and ALP) values were significantly (P < 0.05) higher in Tl and lower in T4. The highest hemoglobin level was observed in T4. White blood cells were significantly (P < 0.05) higher in T3 and T4. No significant difference was observed in, red blood cells, serum total protein, calcium and phosphorous level, packed cell volume, neutrophils, lymphocyte, monocyte, and eosinophil. It is concluded from this experiment that AV and Cv supplementation improved breast yield and carcass weight without any harmful effect on the liver and blood biochemistry. This showed that the supplementation of AV and Cv powder can improve growth performance and it can work as an alternative of AGP.
这项研究旨在评估芦荟（AV）和丁香（Cv）粉补充剂对日本鹌鹑生长性能、胴体质量、血液生化和血液学的影响，并研究将其作为抗生素生长促进剂的替代品的可能性，作为一种天然安全的产品。将 400 只 7 日龄混合性别小鸡分为 4 组，每组 5 个重复，每个重复 20 只鸟，包括（10 只雄性和 10 只雌性）。对照组（T1）的鸡只饲喂含有恩拉霉素（0.02%）的日粮作为抗生素生长促进剂（AGP），而 T2、T3 和 T4 组的鸡只分别补充 0.5、0.5 和 0.25+0.25%的 AV 叶粉、Cv 粉和混合物。结果表明，所有补充组的总饲料摄入量均显著（P<0.05）高于 T1。T4 的体重增加和饲料转化率显著更高（P<0.05），而 T2 和 T3 比 T1 更好（P<0.05）。胸肉产量和胴体重最高（P<0.05）的是 T4，而 T2 和 T3 明显优于 T1。高密度脂蛋白（HDL）最高（P<0.05）的是 T4，而 T2 和 T3 的值高于 T1。血清胆固醇和血清酶（ALT、AST 和 ALP）值在 Tl 中显著升高（P<0.05），在 T4 中降低。T4 中观察到的血红蛋白水平最高。白细胞在 T3 和 T4 中显著升高（P<0.05）。红细胞、血清总蛋白、钙和磷水平、红细胞压积、中性粒细胞、淋巴细胞、单核细胞和嗜酸性粒细胞无显著差异。从这项实验可以得出结论，AV 和 Cv 的补充提高了胸肉产量和胴体重，对肝脏和血液生化没有任何不良影响。这表明 AV 和 Cv 粉的补充可以改善生长性能，可以作为 AGP 的替代品。
