The objective of the study was to assess the effect of diets supplemented with leaf on digestive fermentation, antioxidant status, and haemato-biochemical indices of growing rabbits. leaves (ZLs) of were collected from Sidr trees scattered throughout the city of Medina, Saudi Arabia. Three formulated diets containing 0, 10, and 20 g /Kg diet as supplementation were offered . The organic matter content of ZL was higher. Chemical compositions were comparable in all of the contents of the tested diet. Quantities of gas released from the control diet were higher, and then the gases released decreased significantly ( < 0.05) with the addition of ZL. The values of NH-N were taken as the same trend. The addition of a high level of ZL to rabbit diets led to a decrease ( < 0.05) in the total count of bacteria as well as the number of and spp. However, the number of bacteria was not affected by supplementation. Haemoglobin parameters of the control group and groups 2 and 3 were compared: white blood cell count and red blood cell count. These observations of total protein and albumin within the range of reference values were reported in healthy rabbits, while glucose significantly decreased with the addition of ZL and AST in the blood increased significantly. The values of TP, albumin, and ALT measurements showed no significant differences among groups fed on test diets. Significant differnces in serum immunoglobulins were observed between the groups, while the high levels of ZL supplement led to a significant ( < 0.05) increase in the serum IgA, IgG, and IgM levels. Antioxidants expressed as T-AOC, GSH-Px, T-SOD, and CAT in the blood of animals fed on diets containing high levels of ZL were significantly higher. Higher serum T-AOC, T-SOD, and CAT activities were observed in rabbits supplemented with a high level of ZL compared with the control group ( < 0.05). The supplementation of ZL tended to increase serum GSH-Px activity. The addition of ZL to rabbit diets led to an increase in dry matter intake. On the other hand, there was no significant change in the apparent digestion coefficient of DM, OM, CP, and fat. . Dried ZL supplementation up to 20 g/Kg diet might improve the bacterial community, antioxidants, biochemical parameters and blood constituents of rabbits, and digestibility.
本研究的目的是评估添加枣树叶对生长兔消化发酵、抗氧化状态及血液生化指标的影响。枣树叶（ZLs）采自沙特阿拉伯麦地那市四处散落的椰枣树。提供了三种配方饲料，分别添加0、10和20克/千克饲料作为补充。枣树叶的有机物含量较高。所有受试饲料的化学成分相当。对照饲料释放的气体量较高，添加枣树叶后气体释放量显著降低（P<0.05）。氨氮值呈相同趋势。在兔饲料中添加高水平枣树叶导致细菌总数以及大肠杆菌和沙门氏菌数量减少（P<0.05）。然而，双歧杆菌数量不受补充剂影响。比较了对照组以及第2组和第3组的血红蛋白参数：白细胞计数和红细胞计数。在健康兔中报告了这些总蛋白和白蛋白观察值在参考值范围内，而添加枣树叶后血糖显著降低，血液中的谷草转氨酶显著升高。受试饲料喂养组的总蛋白、白蛋白和谷丙转氨酶测量值无显著差异。各实验组之间血清免疫球蛋白存在显著差异，而高水平枣树叶补充导致血清IgA、IgG和IgM水平显著（P<0.05）升高。以总抗氧化能力（T-AOC）、谷胱甘肽过氧化物酶（GSH-Px）、总超氧化物歧化酶（T-SOD）和过氧化氢酶（CAT）表示的抗氧化剂在喂食高水平枣树叶饲料的动物血液中显著更高。与对照组相比，添加高水平枣树叶的兔血清T-AOC、T-SOD和CAT活性更高（P<0.05）。添加枣树叶倾向于提高血清GSH-Px活性。在兔饲料中添加枣树叶导致干物质摄入量增加。另一方面，干物质、有机物、粗蛋白和脂肪的表观消化系数没有显著变化。添加高达20克/千克饲料的干枣树叶可能改善兔的细菌群落、抗氧化剂、生化参数和血液成分以及消化率。
