淀粉糊化尿素对生长育肥牛生长性能和血浆生化指标的影响OA北大核心CSCDCSTPCD
Effect of Supplemental Levels of Gelatinized Starch-urea on Growth Performance and Plasma Biochemical Indices of Growing-Finishing Beef Cattle
利用60头生长期利木赞杂交牛[ (393.7±15.6) kg]进行饲养试验,以研究淀粉糊化尿素添加水平对肉牛生长性能以及血浆生化指标的影响,为生产中安全利用淀粉糊化尿素( gelatinized starch-urea,GSU)提供科学依据.动物随机分为6组,每组1个重复,每个重复10头牛.对照组饲粮中不添加GSU,处理饲粮以GSU来源氮分别占饲粮总氮的8％、16％、24％、32％和40％.试验期14周,其中预试期l周,正试期13周.结果表明,…查看全部>>
A feeding trial was conducted to investigate the effect of supplemental levels of gelatinized starch-urea (GSU) on growth performance and plasma biochemical indices of growing-finishing beef cattle. Sixty Limousin crossbred bulls [ (393. 7 ±15. 6) kg] were randomly allotted into six groups with 1 replicate each and 10 bulls in each replicate. The bulls in the six groups were fed diets with no supplemental GSU (control) or supplemented with nitrogen from GSU …查看全部>>
