摘　　要：选取120头28日龄断奶仔猪,随机分成4个处理组,即1个对照组和3个试验组,每组3个重复,每个重复10头。对照组饲喂基础日粮,试验1、2、3组分别饲喂基础日粮中血红素铁净添加量为27.5、55.0、85.0 mg/kg的3种试验日粮,研究日粮中添加血红素铁对断奶仔猪的生长性能、血液指标(血红蛋白浓度、免疫球蛋白浓度)的影响。试验正试期13 d。结果表明,血红素铁各添加量组均能够提高仔猪的生长性能,日粮中血红素铁添加量为55 mg/kg时,仔猪平均日增重、饲料转化率较对照组分别提高12.02%和10.27%(P<0.05)。血红素铁对断奶仔猪有良好的促生长作用,也在一定程度上提高了仔猪血液中血红蛋白和IgG浓度。One hundred and twenty 28-day-old weaned piglets were selected and randomly divided into 4 groups, i.e. control, treatment 1, treatment 2 and treatment 3, which were respectively supplied 0,27.5, 55.0 and 85.0 mg/kg heine iron on the basal diet. The effects of heme iron on growth performance and blood biochemical parameters （hemoglobin and IgG） of weaned piglets were researched. The feeding ex- periment was conducted for 13 days. The results as follows： heme iron could improve weaned piglet＇s average daily gain and feed conversion rate, Statistical analysis showed 55.0 mg/kg heme iron in diet in- creased feed conversion rate by 10.27% compared with control group （P〈0.05）. Heine iron had a certain growth promoting effect on weaned piglets, and the hemoglobin concentration in the whole blood and the IgG concentration in the plasma were improved.
