| 摘 要： | 试验将240只1日龄AA肉公鸡,按体重随机分为5个处理,分别饲喂基础饲粮和添加100mg/kg和200mg/kg硫酸锰(MnSO4)和氨基酸锰(MnAA)的饲粮42d。结果表明:添加100mg/kg锰显著降低4～6周耗料增重比(F/G)(P0.06);添加100mg/kg和200mg/kg锰显著增加肝脏锰含量(P0.001),同时有提高腿肌率,降低腹脂率的趋势(P0.10);添加100mg/kg MnAA血清总蛋白(TP)显著高于添加100mg/kg MnSO4(P0.09),而添加100mg/kg Mn AA和MnSO4组碱性磷酸酶(ALP)活性分别较对照组高35.7%和21.0%。表明添加100mg/kg锰可降低肉鸡生长后期F/G和提高肝脏锰含量,但是2种锰源间差异不显著;但Mn添加100mg/kg Mn AA比MnSO4可能更有效地促进肉鸡体内蛋白质的合成代谢。 |

| Abstract: | In the experiment the total of 240 one-day-old Arbor Acres male broilers were randomly allotted into 5 groups.They were fed the basal diet and corn-soybean meal-based diet supplemented with 100,200 mg/kg MnSO4 or MnAA for 42 days.The result showed that supplementing 100 mg/kg Mn treatment significantly decreased 4-6 weeks F/G(P < 0.06).Supplementing 100 and 200mg/kg Mn treatment significantly increased Mn concentration of liver(P < 0.001),at the same time had the trend to enhance the Percentage of thigh muscle and reduce Percentage of abdominal fat.Supplementing 100mg/kg MnAA had significantly made TP of serum higher compared to supplementing MnSO4(P < 0.09).Adding 100 mg/kg MnAA and MnSO4 treatments comparing to the control increased ALP by 35.7% and 21.0% respectively(P > 0.10).The result indicate that adding 100mg/kg Mn decreased 22-42 days F/G,and increased Mn concentration of liver,but there was not significant difference between the two Mn sources;and the addition of 100mg/kg Mn as MnAA might promote the protein suythesis in broilers more effectively than that of 100mg/kg Mn as MnSO4. |
