| 摘 要： | 试验旨在研究添加复合酶对临武鸭骨粉和羽毛粉养分利用率的影响,选用40只体重2.0kg左右的健康成年临武鸭公鸭,随机分为5组,每组8个重复,采用绝食强饲法进行代谢试验,测定添加酶制剂前后临武鸭对骨粉和羽毛粉中DM、CP、粗脂肪、氨基酸、能量等的表观和真可利用率。结果表明：添加复合酶制剂临武鸭对骨粉中干物质、粗蛋白、粗脂肪、粗灰分、钙和总磷的真可利用率分别为提高了9.50%、7.72%、3.46%、8.52%、1.49%和18.94%;骨粉的鸭表观代谢能和真代谢能分别提高了3.64%和5.85%;氨基酸的真可利用率提高了2.65%-24.52%。临武鸭对羽毛粉中DM、CP、EE的真可利用率分别为4.12%、3.21%和1.64%;羽毛粉的鸭AME和TME分别提高了2.38%和2.14%;氨基酸的真可利用率提高了0.75%-12.63%。试验结果显示,在骨粉和羽毛粉中添加复合酶制剂提高了临武鸭的养分及氨基酸利用率和代谢能。

| Abstract: | To study the nutrient utilization of Linwu ducks affected by bone meal and feather meal supplemented with complex enzyme,a total of 40 healthy adult male Linwu ducks with the body weight of about 2.0kg were randomly and evenly divided into 5groups.Metabolic tests were carried out by＇hunger strike- gavage method＇to determine apparent and true DM,CP,EE,AA and energy utilization of bone meal and feather meal before and after adding complex enzyme.The results showed that bone meal supplemented with complex enzyme improved the true utilization rates of DM,CP,EE,Ash,Ca and TP by9.50%,7.72%,3.46%,8.52%,1.49% and 18.94%,respectively;AME and TME of bone meal were increased by 3.64% and 5.85%;amino acids true utilization were increased by 2.65%-24.52%.Feather meal adding with complex enzyme improved the true utilization rates of DM、CP and EE by 4.12%、3.21%and 1.64%;AME and TME of feather meal were increased by 2.38%and 2.14%;amino acids true utilization were increased by 0.75%-12.63%.The test results indicate that bone meal and feather meal adding with complex enzyme could improve Linwu ducks nutrient and AA utilization and metabolic energy. |
