摘要

本试验旨在研究锰对5~16周龄五龙鹅血清生化指标、组织锰沉积量、抗氧化能力及胫骨发育的影响，以确定鹅饲粮中锰的适宜添加水平。试验选用5周龄体重相近的五龙鹅360只，随机分为6组，每组6个重复，每个重复10只（公母各占1/2）。各组分别在基础饲粮（锰含量为20.00 mg/kg）中添加0（Ⅰ组）、30（Ⅱ组）、60（Ⅲ组）、90（Ⅳ组）、120（Ⅴ组）、150 mg/kg（Ⅵ组）的锰。试验期12周。结果表明：1）各组血清碱性磷酸酶活性及甘油三酯、总胆固醇含量差异不显著（P>0.05）。2）Ⅳ、Ⅴ组血清、心脏、肝脏中锰沉积量极显著高于Ⅰ组（P<0.01），胰脏中锰沉积量显著高于Ⅰ组（P<0.05）。3）Ⅳ、Ⅴ组总抗氧化能力和谷胱甘肽过氧化物酶活性显著或极显著高于Ⅰ组（P<0.05或P<0.01），丙二醛含量极显著低于Ⅰ组（P<0.05）。4）Ⅳ、Ⅴ组骨强度、骨重及粗灰分、钙、磷、锰含量显著或极显著高于Ⅰ组（P<0.05或P<0.01）。由此可见，适宜锰添加水平能够提高5~16周龄五龙鹅组织器官中锰沉积量，提高机体抗氧化能力，促进胫骨发育，建议饲粮锰添加水平为90~120 mg/kg。

Abstract

This experiment was conducted to study the effects of manganese on serum biochemical indexes, tissue manganese deposition, antioxidant ability and tibia development of Wulong geese aged from 5 to 16 weeks, and to find the appropriate supplemental level of manganese in Wulong geese diets. A total of 360 five-week-old Wulong geese with similar average body weight were randomly divided into 6 groups with 6 replicates per group and 10 geese per replicate (half male and half female). Geese in the groups were fed the basal diet (manganese content was 20.00 mg/kg) supplemented with 0 (group Ⅰ), 30 (group Ⅱ), 60 (group Ⅲ), 90 (group Ⅳ), 120 (group Ⅴ) and 150 mg/kg (group Ⅵ) manganese, respectively. The experiment lasted for 12 weeks. The results showed as follows: 1) there were no significant effects on alkaline phosphatase activity, triglyceride and total cholesterol contents in serum among all groups (P>0.05). 2) The serum, heart and liver manganese deposition in groups Ⅳ and Ⅴ was significantly higher than that in group Ⅰ (P<0.01), and the pancreas manganese deposition in groups Ⅳ and Ⅴ was significantly higher than that in group Ⅰ (P<0.05). 3) The total antioxidant capacity and glutathione peroxides activity in groups Ⅳ and Ⅴ were significantly higher than those in group Ⅰ (P<0.05 or P<0.01), while the malondialdehyde content was significantly lower than that in group Ⅰ (P<0.05). 4) The bone strength, bone weight and the contents of ash, calcium, phosphorus and manganese in groups Ⅳ and Ⅴ were significantly higher than those in group Ⅰ (P<0.05 or P<0.01). In conclusion, dietary manganese at appropriate supplemental level can improve tissue deposition, antioxidant ability, and promote the tibia development of Wulong geese aged from 5 to 16 weeks, and the optimal supplemental level of manganese is 90 to 120 mg/kg.
