【摘要】：本試驗(yàn)旨在研究飼糧中不同錳水平對(duì)1~4周齡五龍鵝血清脂類代謝、抗氧化指標(biāo)及器官組織中錳沉積量的影響,以確定鵝飼糧中錳適宜添加水平。試驗(yàn)選用1日齡體重相近的五龍鵝360只,隨機(jī)分為6個(gè)組,每組6個(gè)重復(fù),每個(gè)重復(fù)10只鵝(公母各占1/2)。對(duì)照組(Ⅰ組)飼喂基礎(chǔ)飼糧(錳含量為20 mg/kg),試驗(yàn)組分別飼喂在基礎(chǔ)飼糧中添加30(Ⅱ組)、60(Ⅲ組)、90(Ⅳ組)、120(Ⅴ組)和150 mg/kg錳的試驗(yàn)飼糧(Ⅵ組)。試驗(yàn)期4周。結(jié)果表明:1)Ⅳ、Ⅴ、Ⅵ組血清甘油三酯和總膽固醇含量極顯著高于Ⅰ組(P0.01),Ⅲ組顯著高于Ⅰ組(P0.05)。各組血清堿性磷酸酶活性差異不顯著(P0.05)。2)Ⅳ、Ⅴ、Ⅵ組血清總抗氧化能力和谷胱甘肽過氧化物酶活性極顯著高于Ⅰ組(P0.01),Ⅲ組顯著高于Ⅰ組(P0.05);Ⅴ組血清丙二醛含量極顯著低于Ⅰ、Ⅱ、Ⅲ組(P0.01),Ⅳ、Ⅵ組顯著低于Ⅰ、Ⅱ、Ⅲ組(P0.05)。3)Ⅳ、Ⅴ、Ⅵ組血清、心臟、肝臟和胰臟中錳沉積量極顯著高于Ⅰ組(P0.01),Ⅱ、Ⅲ組血清、心臟和肝臟中錳沉積量顯著高于Ⅰ組(P0.05)。由此可見,飼糧中添加錳能提高五龍鵝血清甘油三酯、總膽固醇含量,增強(qiáng)機(jī)體抗氧化能力,增加器官組織中錳沉積量。建議鵝飼糧中錳適宜添加水平為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，
