Heme and Non-heme Iron on Growth Performances, Blood Parameters, Tissue Mineral Concentration, and Intestinal Morphology of Weanling Pigs

This experiment was conducted to evaluate the effects of heme and non-heme iron sources on growth performances, blood parameters, tissue mineral concentration, and intestinal morphology in weanling pigs.

Zusammenfassung:This experiment was conducted to evaluate the effects of heme and non-heme iron sources on growth performances, blood parameters, tissue mineral concentration, and intestinal morphology in weanling pigs. At 25 days of age, 32 newly weaned piglets (Duroc × Landrace × Yorkshire; 8.66 ± 0.59 kg) were allocated to one of the following dietary treatments: control group (basal diet with no extra iron addition), FeSO 4 group (basal diet + 100 mg Fe/kg as FeSO 4 ), Fe-Gly group (basal diet + 100 mg Fe/kg as Fe-Gly), and Heme group (basal diet + 100 mg Fe/kg as Heme). Each treatment had eight replicates and one pig per replicate. The experiment lasted for 28 days. The results showed that compared with basal diet, supplement with 100 mg/kg iron can increase ADG of the piglets, especially in the late experiment period (15~28 days). Heme significantly increased the a * value of longissimus dorsi muscle of piglets when compared with other iron sources ( P
