【摘要】：本试验旨在研究饲粮中不同锰水平对1~4周龄五龙鹅血清脂类代谢、抗氧化指标及器官组织中锰沉积量的影响,以确定鹅饲粮中锰适宜添加水平。试验选用1日龄体重相近的五龙鹅360只,随机分为6个组,每组6个重复,每个重复10只鹅(公母各占1/2)。对照组(Ⅰ组)饲喂基础饲粮(锰含量为20 mg/kg),试验组分别饲喂在基础饲粮中添加30(Ⅱ组)、60(Ⅲ组)、90(Ⅳ组)、120(Ⅴ组)和150 mg/kg锰的试验饲粮(Ⅵ组)。试验期4周。结果表明:1)Ⅳ、Ⅴ、Ⅵ组血清甘油三酯和总胆固醇含量极显著高于Ⅰ组(P0.01),Ⅲ组显著高于Ⅰ组(P0.05)。各组血清碱性磷酸酶活性差异不显著(P0.05)。2)Ⅳ、Ⅴ、Ⅵ组血清总抗氧化能力和谷胱甘肽过氧化物酶活性极显著高于Ⅰ组(P0.01),Ⅲ组显著高于Ⅰ组(P0.05);Ⅴ组血清丙二醛含量极显著低于Ⅰ、Ⅱ、Ⅲ组(P0.01),Ⅳ、Ⅵ组显著低于Ⅰ、Ⅱ、Ⅲ组(P0.05)。3)Ⅳ、Ⅴ、Ⅵ组血清、心脏、肝脏和胰脏中锰沉积量极显著高于Ⅰ组(P0.01),Ⅱ、Ⅲ组血清、心脏和肝脏中锰沉积量显著高于Ⅰ组(P0.05)。由此可见,饲粮中添加锰能提高五龙鹅血清甘油三酯、总胆固醇含量,增强机体抗氧化能力,增加器官组织中锰沉积量。建议鹅饲粮中锰适宜添加水平为90~120 mg/kg。
[Abstract]:The purpose of this study was to study the effects of different dietary manganese levels on serum lipid metabolism, antioxidant index and manganese deposition in organs and tissues of Wulong geese at the age of 1 and 4 weeks. In order to determine the appropriate level of manganese supplementation in the diet of geese, 360 Wulong geese with similar body weight of one day were randomly divided into 6 groups with 6 replicates in each group. The control group (group I) was fed with a basal diet (manganese content of 20 mg / kg 路kg ~ (-1)), and the experimental group was fed a diet supplemented with 30 mg 路kg ~ (-1) mn (group 鈪，
