Abstract

A trial was conducted to access the impact of varying levels of dietary protein (CP) and cold-pressed oil on hematological parameters, liver and kidney function, antioxidant and immunoglobulin indices and lipid profile of Japanese quail at the laying period. A number of 324 mature ten-week of age Japanese quails (216 females and 108 males) were selected. The red blood cells were increased in response to marjoram and thyme oil applied separately or together when comparing with control group (p < 0.05). Cholesterol, triglyceride, low-density lipoprotein and total lipid levels were decreased significantly in response to these oils in birds 2 to 5 month of age compared to the comparing group. Superoxide dismutase activity increased in response to dietary supplementation with marjoram and thyme compared to zero additives group and other groups (p < 0.01). The glutathione and malondialdehyde levels (p < 0.01) decreased due to supplementation with thyme oil alone and in combination with marjoram oil compared to the control and other groups in 2- to 5-month-old birds. It could be concluded quails fed a diet encompassing 18 or 20% CP or supplemented with marjoram or thyme oil exhibited improved antioxidant indices and lipid profile without any harmful influence on the other parameters.

摘要

进行了一项试验，以了解不同水平的日粮蛋白质 (CP) 和冷榨油对产蛋期日本鹌鹑血液学参数、肝肾功能、抗氧化和免疫球蛋白指数以及血脂状况的影响。选择了 324 只成熟的 10 周龄日本鹌鹑（216 只雌性和 108 只雄性）。与对照组相比，马郁兰和百里香油单独或一起使用时红细胞增加（p < 0.05)。与对照组相比，2 至 5 个月大的鸡对这些油的反应显着降低了胆固醇、甘油三酯、低密度脂蛋白和总脂质水平。与零添加剂组和其他组相比，添加马郁兰和百里香的膳食补充剂的超氧化物歧化酶活性增加（p  < 0.01）。谷胱甘肽和丙二醛水平 ( p < 0.01) 在 2 至 5 个月大的鸡只中，由于单独补充百里香油和与马郁兰油联合使用而降低。可以得出结论，喂食含有 18% 或 20% CP 或补充马郁兰或百里香油的饮食的鹌鹑表现出改善的抗氧化指数和脂质分布，而对其他参数没有任何有害影响。
