饲粮粗蛋白质和代谢能水平对9~10周龄四川白鹅生产性能和氮平衡的影响OA北大核心CSCDCSTPCD
Effects of Dietary Crude Protein and Metabolizable Energy Levels on Performance and Nitrogen Balance of Sichuan White Geese Aged from 9 to 10 Weeks
本试验旨在研究饲粮粗蛋白质( CP)和代谢能( ME)水平对9~10周龄四川白鹅生产性能和氮平衡的影响。采用3×3双因素试验设计,饲粮 ME 水平分别为12.86、12.13、11.43 MJ/kg,CP水平分别为15%、13%、11%。选择432只56日龄体重相近的健康四川白鹅,随机分成9组,每组4个重复,每个重复12只。试验期为14 d。在试验第8天,每组挑选8只体重接近各组平均体重的试验鹅进行代谢试验。结果表明：1) CP水平对日干物质( …查看全部>>
This experiment was conducted to study the effects of crude protein ( CP) and metabolizable energy ( ME) levels on performance and nitrogen balance of Sichuan white geese aged from 9 to 10 weeks. Four hun-dred and thirty two 57-day-old healthy Sichuan white geese with similar body weight were used in a 3×3 double factorial design trial and randomly allocated into 9 groups with 4 replicates in each group and 12 geese in each replicate. The geese were fed 9 ex…查看全部>>
