1、广西大学硕士学位论文L--肉碱对南丹瑶鸡生产性能、蛋品质、精液品质以及生化指标的影响姓名:邹丽丽申请学位级别:硕士专业:动物营养与饲料科学指导教师:梁远东20120630L一肉碱对南丹瑶鸡种鸡生产性能、蛋品质、精液品质及生化指标的影响摘要本试验一旨在研究添加L一肉碱饲粮对广西南丹瑶鸡种公鸡繁殖期性能、精液品质、配种性能、血清血浆部分生化指标的影响以及相关性分析。采用单因子完全随机设计,选用37周龄种公鸡24只,每个处理4个重复,每个重复1只公鸡,L一肉碱添加量为6个处理水平分别是0mg/kg、125mg/kg、25
2、0mg/kg、375mg/kg、500mg/kg、750mg/kg。另选健康同周龄种母鸡480只,也随机分为6组,每组80只,分别对应各试验组种公鸡。试验从2011年6月4日持续到2011年10月8日,为期18周。试验结果:日粮中添加不同水平的L一肉碱极显著提高了种公鸡的精液量、精子活力、精子密度、有效精子数QO.05);对受精蛋孵化率、健雏率有显著的提高作用(p3、1)、显著提高AKP的活力QO.05);显著降低了精浆中的TC含量QO.05)。El粮中添加不同水平的L一肉碱与公鸡全期体增重呈显著正相关Q4、p5、4只,每个处理216只,试验期18周。试验结果:日粮中添加不同水平的L一肉碱显著提高了种母鸡的产蛋率、受精率、受精蛋孵化率(pO.05);对哈氏单位有显著的提高作用QO.05);对母鸡的血清中AKP、GSH.Px有显著的提高作用(p6、O.05);对蛋黄中的胆固醇含量有显著的降低作用(p7、INNAN.DAN.YA0BREEDINGCOCKSABSTRACTThepaperstudiedtheeffectsofdifferentlevelsofdietaryL-carnitineonperformanceofgrowth,semenquality,reproductiveperformance,somephysiologicalandbiochemicalindicesinserumandseminalplasmaofcocks.Linearregressionanalysiswascarriedon8、toexploretherequirmentsofL.camitineofNan-dan·yaocockduringreproductiveperiod.Experimentone:Thestudyadoptedone-factorcompletelyrandomdistractdesign.Accordingto1factors6horizontalmet
