摘要

本试验旨在研究二肽螯合铁对仔猪生长性能、血清铁和抗氧化指标的影响。选取40日龄健康三元杂交仔猪80头,随机分为对照组和试验组2个组,每组4个重复,每个重复10头猪。对照组和试验组饲粮中的铁添加量均为180 mg/kg(以铁计),对照组仅添加硫酸亚铁,试验组仅添加二肽螯合铁。试验期21 d。结果表明,与对照组相比,试验组平均日增重(ADG)提高了10.37%(P>0.05),料重比(F/G)降低了5.59%(P<0.05);试验组血清铁含量显著高于对照组(P<0.05),血清铁蛋白和血红蛋白含量高于对照组(P>0.05);试验组血清超氧化物歧化酶(SOD)活性显著高于对照组(P<0.05),血清丙二醛(MDA)含量显著低于对照组(P<0.05)。由此可见,二肽螯合铁可明显促进仔猪生长,改善仔猪体内铁代谢状况,增强仔猪抗氧化能力。

Abstract

The aim of the present study was to investigate the effects of ferrous N-carbamylglycinate chelate (Fe-CGly) on growth performance, serum iron and antioxidant indices of piglets. Eighty piglets (Duroc×Landrace×Large Yorkshire) at 40 days of age were randomly assigned to 2 groups with 4 replicates per group and 10 piglets per replicate. The diets of control group and experimental group all contained 180 mg/kg iron, the diet of control group only supplemented with Fe2SO4·7H2O, and the diet of experimental group only supplemented with Fe-CGly. The experiment lasted for 21 days. The results showed as follows:compared with the control group, the average daily gain (ADG) of experimental group was increased by 10.37% (P>0.05), while the ratio of feed to gain was decreased by 5.59% (P<0.05). The serum iron content of experimental group was significantly higher than those of control group (P<0.05), the serum ferritin and hemoglobin contents of experimental group were higher than that of control group (P>0.05). The serum superoxide dismutase (SOD) activity of experimental group was significantly higher than that of control group (P<0.05), while the malonaldehyde (MDA) content of experimental group was significantly lower than that of control group (P<0.05). Thus, it can be concluded that the Fe-CGly has benefits on improving growth performance, iron metabolism and antioxidant status in piglets.
