摘要

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 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。

Abstract

To study the effects of iron and zinc complex amino acid chelate on blood biochemical indexes, immunoglobulin content in serum, iron and zinc contents in hair and apparent digestibility of iron and zinc of finishing 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 (offered by iron and zinc complex amino acid chelate). The results showed as follows: 1) no significant differences 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) contents of experimental group 2 were significantly higher than those of the control group (P<0.05). 3) Iron content 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 control 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 significantly lower than that of the control group (P<0.05). There was no significant difference in apparent digestibility 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.
