乳猪小肽螯合铁的补铁效果

The Effect of Small Peptide Chelated Iron in Suckling Pigs

采用小肽螯合铁作为补铁剂 ,妊娠和泌乳母猪以及乳猪为研究对象 ,测定母猪初乳铁的含量 ,乳猪 5、10、14和 2 1日龄的血红蛋白 (Hb)以及乳猪 14和 2 1日龄的血清铁蛋白 (SF)浓度 .结果表明 ,小肽螯合铁比硫酸亚铁能够更有效地进入母乳 ,母猪补小肽铁可增加乳猪铁的获得 ,但不能解决乳猪的缺铁问题 ;乳猪补小肽螯合铁不但有较高的Hb水平 ,而且体内铁储备量高于补右旋糖苷铁 ,可满足乳猪铁的需要 .

The experiment was conducted with sows and their piglets, to study the response of colostrums iron content, Hb value, serum ferrintin(SF) concentration to small peptide chelated iron in neonatal piglets. The results showed that supplement with 80 mg/kg small peptide chelated iron(as iron) in sow ration from 14 days before parturition to 21 days after parturition increased colostrum iron content of sows by 80% and the Hb level of their piglets at 14 days of age was significantly elevated when compared to FeSO 4 group(P<0.05). The Hb level of piglets orally administrated with small peptide chelated iron and injected with iron dextran was optimum at 14 and 21 days of age. The SF concentration piglets orally administrated with small peptide chelated iron were significant higher than that injected with iron dextran( P <0.05). Those result suggested that small peptide chelated iron can effectively prevent piglet anemia.
