补铁对高原瘦肉型母系猪白系哺乳仔猪的影响

Effect of Supplementary Iron on Suckling piglet with Bai-line of Maternal-ling Pig of Plateau Lean-meat-type

选用高原瘦肉型母系猪白系哺乳仔猪25窝261头,随机按窝分为两组。试验组13窝139头仔猪2日龄,采用深部肌肉注射的方法,头均补给右旋糖苷铁1ml(含铁100mg),对照组12窝122头不注射,在相同条件下哺乳至35日龄断奶。结果表明,试验组窝均成活8.6头,比对照组(7.8头)多0.8头,差异显著(P<0.05);断奶个体重分别为7.2kg和7.0kg差异不显著(P>0.05);窝均收入试验组比对照组提高13.3%,效益明显。

261 Bai-line piglets of maternal-line pig of plateau lean-meat-type（25 lieters ） were selected and randomly divided into two groups.The 139 piglets（ 13 littersl at the age of two days in the test group were injected with 1 ml iron dextran （ 100 mg/ml） per piglet by means of deep muscle injection, and 122 piglets （ 12 litter） in the control group weren＇t injected. All the piglets were nursed under same condition until they were weaned at the age of 35 days. The results showed that there were average survival 8.6 piglets per litter in the test group which was 0. 8 piglets more than that in the control group which was 7.8 piglets （ P 〈 0. 05 ）. The weaning weight of piglets in the test and control groups were 7.2 and 7. 0kg（ P 〉 0. 05 ）, respectively. The average litter income in the test group was 13.3% more than that in the control group and there was an obvious economical benifit.
