| This experiment was conducted to study the effects of three different Iron supplement agents (Ferrous Sulfate (FS), Ferrous Fumarate (FF) and Methionine Chelate Iron (MCI)) on growth performance and biochemical indicators of sucking piglets. One hundred and twenty crossbred (DurocxLarge WhitexLandrace) piglets (7±2d) were used to study in a one factorial design. The sucking piglets were divided into three groups (three replicates/group and ten birds/replicate). The three groups included:①100mg/kg FS group;②100mg/kg FF group;③100mg/kg MCI group. Growth performances of each period (week) were determined. At the age of7and14day-old, blood was collected form each replicate to determine hemoglobin (Hb) content, quantity red blood (RBC) cell quantity, packed cell volume(PCV). The results showed that:(1) Growth performance in15-21d,22-28d,7-28d in sucking piglets of FF group and MCI group were all higher extremely significantly than those of FS group(P<0.05).(2)Blood indexes in sucking piglets of FF group and MCI group were all higher extremely significantly than those of FS group(P<0.05). Growth performance and Blood indexes in sucking piglets of FF group and MCI group were not significantly.(3) Compared with the control group and ferrous sulfate, FF group and MCI group were significantly decreased in diarrhea rate (P<0.05),and significantly increased in survival rate(P<0.01). But there was no obvious difference in diarrhea rate and survival rate of FF group and MCI group.These results indicate that, growth performance and blood indexes in sucking piglets of FF group and MCI group were all higher extremely significantly than those of FS group. The effects of FF group and MCI group on growth performance and biochemical indicators of sucking piglets are resemblance. |
