Study on Fatty Liver Performance of Landes Geese and Mule Ducks and Dynamics of Lipid Storage in Fatty Liver of Landes Geese in Response to Brown Rice-based Overfeeding Diets
饲粮诱导蹼足类家禽肥肝形成的机理仍不清楚(Hermier et al., 2003)。本文首先对金优402等4种湖北省种植面积较广的优质饲料早稻糙米的营养价值进行评定;然后与玉米和小麦进行对照,研究金优402糙米作为超饲养原料对朗德鹅和骡鸭肥肝性能的影响;最终按单因子试验设计方法,分别在金优402糙米为主要原料的超饲养饲粮中添加不同水平的大豆色拉油、胆碱和肉碱,研究其对朗德鹅肥肝性能、脂类代谢、肥肝组成成分及肝脏组织和肝细胞中脂类沉积和分布规律的影响。试验结果分别摘要如下:
1 金优402等4种早稻糙米营养价值评定
目的:评定金优402、金优152、9530和鄂早6号等4种饲料早稻的营养价值。方法:以优质玉米鲁单50、优质蛋白玉米(QPM)津玉34、2种优质饲料早稻(FEP)湘早籼24和威优56的糙米以及优质中稻金优63的糙米为对照,通过真代谢能(TME)法和高效液相色谱法(HPLC)对金优402、金优152、鄂早6号和9530等4种早稻糙米的总能、粗蛋白质和氨基酸含量及其利用率进行研究分析。结果:(1)除9530外,金优402等3种早稻糙米的总能含量均...
【英文摘要】
The mechanism of dietary-induced fatty liver of Palmipedes remains puzzling (Hermier et al., 2003). Firstly, the nutritional values of four varieties of early paddy brown rice, Jinyou402, Jinyoul52, Ezao6 and 9530, planted widely in Hubei Province were evaluated in this dissertation. Secondly, compared to maize and wheat diets, the effects of brown rice overfeeding diet of Jinyou402 on performance of fatty liver of Landes Geese and Mule Ducks were demonstrated. At last, using singular factor design, differe...
