摘　　要：试验分育雏期和育成期两阶段进行,分别采用L9(34)正交设计探讨日粮不同代谢能、粗蛋白质、钙和有效磷水平对广西合浦鹅养分利用率的影响。结果表明:育雏期,当日粮代谢能为11.30 MJ/kg、粗蛋白质为18%、钙为1.0%和磷为0.5%时,合浦鹅对养分表观代谢率最高;育成期,当日粮代谢能为11.60 MJ/kg、粗蛋白质为15%、钙为0.7%和磷为0.5%时,合浦鹅对养分表观代谢率最高。The experiment was carried out in starting period and finishini period to investigate the effects of different kinds of meta-bolic energy, crude protein, calcium and phosphor in rations on the utilization rate of nutrients for Hepu gooses by means of L9（3^4） or-thogonal design respectively. The results indicated that the apparent metabolic rate of nutrients for Hepu gooses was the highest when the metabolic energy was 11.30 MJ/kg, crude protein was 18% , calcium was 1.0% and phosphor was 0. 5 % of rations during starting period ; the apparent metabolic rate of nutrients for Hepu gooes was the highest when the metabolic energy was 11.60 MJ/kg, crude protein was 15%, calcium was 0. 7% and phosphor was 0. 5% during the finishing period.
