Using the littermate grouping method,112 Duroc×Gansu white piglets in 14 litters were randomly divided into 3 groups according to their sex,body weight and the position of the sows' teats.Piglets in the treatment group 1 were injected with the iron preparation of high concentration,the iron hemopietin (Fe content 150mg/ml) the ones in the treatment group 2 were injected with the iron preparation of low concentration the dextran iron (Fe content 50mg/ml) Each piglet in the treatment groups was given Fe 150mg by I.M,but not in the control group.At the age of 35 days the daily gain in treatment groups 1 and 2 was 71.86%,71.11% higher than that of the control group with high significant difference (P<0.01) resp.but no significant difference (P>0.05) between the two treatment groups.At the age of 12,25and 35 days, Hb contents in the two treatment groups were all 110～130g/L while that of the control group at the age of 12 and 25 days was 68～86g/L,there was high significant difference(P<0.01) between the control and two treatment groups,but no significant difference (P>0.05) between the two treatment groups The best economic benefit belongs to the treatment group 1.
