赖氨酸螯合铁在母猪日粮中的应用

Application of Lysine Chelated Iron in Swine Dietary

试验分 4组。用赖氨酸螯合铁和硫酸亚铁分别进行饲喂妊娠、哺乳期母猪的试验 ,并同时用葡聚糖铁给初生仔猪作补铁的试验。结果表明 :饲喂赖氨酸螯合铁组的母猪所生仔猪 ,比对照组母猪所生仔猪断奶成活率高 9.2个百分点 (P <0 .0 5 ) ,平均断奶重高 18.8% (P <0 .0 1) ;比饲喂硫酸亚铁组母猪所生仔猪断奶成活率高 3.1个百分点 (P >0 .0 5 ) ,平均断奶重高 9.9% (P <0 .0 5 )。而与给 3日龄仔猪注射葡聚糖铁组相比 ,成活率和断奶重分别提高 0 .2个百分点和 2 .3% (P >0 .0 5 )。

The trial was consisted of four groups. The pregnant and lactating swines were fed on the feeds including lysine chelated iron, while the piglets were fed on the diets including dextran iron. The results showed that the survival rate of the piglets from the swine fed on the feed including lysine chelated iron was increased by 9.2 percentage points ( P <0.05), and the average weaning weight was increased by 18.8% ( P <0.01) comparing with that of the control group. The survival rate was increased by 3.1 percentage points ( P <0.05), and the average weaning weight was increased by 9.9%( P <0.05) comparing with that of the group fed on the feeds including ferrous sulfate. The survival rate and the weaning weight were increased by 0.2 percentage points and 2.3% ( P <0.05) respectively comparing with that of the dextran iron injected group.
