本试验旨在研究复合氨基酸络合铁、锌对肥育猪血液生化指标，血清中免疫球蛋白含量，毛发中铁、锌含量及铁、锌表观消化率的影响。选择体重[（55．63±1．33）kg]相近的“杜×长×大”肥育猪36头，随机分至对照组和2个试验组，每组3个重复，每个重复4头猪。对照组饲喂铁、锌含量均为100 mg/kg（由硫酸亚铁、硫酸锌提供）的基础饲粮，试验1组饲喂铁、锌含量均为50 mg/kg（由硫酸亚铁、硫酸锌提供）＋50 mg/kg（由复合氨基酸络合铁、锌提供）的基础饲粮，试验2组饲喂铁、锌含量均为100 mg/kg（由复合氨基酸络合铁、锌提供）的基础饲粮。结果表明：1）3组间的红细胞数量、血细胞压积、血清免疫球蛋白A和免疫球蛋白M含量无显著差异（ P＞0．05）。2）试验2组的血红蛋白含量和血清免疫球蛋白 G含量显著高于对照组（ P＜0．05）。3）试验2组毛发中铁含量显著高于对照组（ P＜0．05），试验2组毛发中锌含量显著高于试验1组和对照组（ P＜0．05）；4）试验2组粪中铁含量和试验2组、试验1组粪中锌含量显著低于对照组（ P＜0．05）；3组间铁和锌表观消化率无显著差异（ P＞0．05）。由此可见，添加复合氨基酸络合铁、锌可显著增加肥育猪血红蛋白、血清免疫球蛋白G含量及毛发中铁、锌含量，显著降低粪中铁、锌含量。

To study the effects of iron and zinc complex amino acid chelate on blood biochemical indexes,im-munoglobulin content in serum,iron and zinc contents in hair and apparent digestibility of iron and zinc of fin-ishing pigs,thirty-six finishing pigs( Duroc × Landrace × Yorkshire ) with an average initial body weight of (55.63±1.33)kg were selected and randomly allotted to three groups. There were three replicates per group and four pigs in each replicate. Pigs of the control group fed a basal diet with 100 mg/kg iron and zinc( offered by ferrous sulfate and zinc sulfate),those of experimental group 1 fed the basal diet with 50 mg/kg iron and zinc( offered by ferrous sulfate and zinc sulfate)+50 mg/kg iron and zinc( offered by iron and zinc complex amino acid chelate),and those of experimental group 2 fed the basal diet with 100 mg/kg iron and zinc( of-fered by iron and zinc complex amino acid chelate ). The results showed as follows:1 )no significant differ-ences were observed in the number of red blood cells,hematocrit,immunoglobulin A and immunoglobulin M contents in serum among the three groups( P>0.05). 2)The hemoglobin and immunoglobulin G( IgG)con-tents of experimental group 2 were significantly higher than those of the control group( P<0.05). 3)Iron con-tent in hair of experimental group 2 was significantly higher than that of the control group(P<0.05);zinc content in hair of experimental group 2 was significantly higher than that of experimental group 1 and the con-trol group( P<0.05). 4)Iron content in feces of experimental group 2 was significantly lower than that of the control group( P<0.05);zinc content in feces of experimental group 2 and experimental group 1 was signifi-cantly lower than that of the control group( P<0.05). There was no significant difference in apparent digesti-bility of iron and zinc among the three groups( P>0.05). It is concluded that iron and zinc complex amino acid chelate increase the contents of hemoglobin,IgG in serum and iron,zinc in hair,and decrease iron and zinc contents in feces.
