| 摘 要： | 以添加 1 0 0 0和 1 50 0mg/kg甜菜碱的饲粮分别饲喂生长肥育猪 ,均显著提高生长肥育猪日增重 ,其中以 1 0 0 0mg/kg组效果更为明显 ,生长期提高了 1 3.2 0 % (P <0 .0 1 ) ,肥育期提高了 5.68% (P <0 .0 5)。甜菜碱增加了猪肝脏甜菜碱高半胱氨酸甲基转移酶 (BHMT)活力 ,生长期总活力与比活力 1 50 0mg/kg组分别提高了 2 3.0 8% (P <0 .0 1 )和 1 8.1 8% (P <0 .0 5) ,肥育期则以 1 0 0 0mg/kg组更为明显 ,总活力与比活力分别提高 1 6.33% (P <0 .0 5)和 1 5.63% (P <0 .0 5)。肉碱含量分析表明 ,甜菜碱均显著提高了生长猪肝脏和肌肉游离肉碱的含量 ,而肥育期仅以肝脏游离肉碱及肌肉酸不溶肉碱含量上升显著

| Abstract: | Ninety growing-finishing pigs were used to study the effect of 0,1000,1500mg/kg betaine on growth performance and methyl transfer function. The results indicated:1000mg/kg betaine increased growing and finishing stage average daily gain(ADG) by 13.20%(P<0.01) and 5.68%(P<0.05) respectively,the whole stage ADG were increased by 12.74%(P<0.01); Betaine enhanced betaine-homocysteine(BHMT) methyltransferase activity in liver, in 1000mg/kg group, total and special activity were enhanced by 22.38%(P<0.01)和18.18%(P<0.05) in growing stage, and 16.33%(P<0.05) and 15.63%(P<0.05) was increased in finishing stage; Free-carnitine was improved significantly in liver and LD by adding betaine during the growing stage, but only the free-carnitine in liver and acid-insoluble carnitine in LD were changed obviously during the finishing stage. |
