The objective of this study was to investigate the effects of dietary ginger and Scutellaria on antioxidant capacity and IgG concentration in plasma and colostrum of sows. Twenty-four sows(Landrace×Yorkshire) in parity 2 were assigned to 3 treatment groups(8 sows per treatment) from 30 day before farrowing up to weaning on day 21 after farrowing. The treatment diets included 1) CON(Basal diet), 2) GDP(0.3% ginger dry powder was used as the replacement of wheat in basal diet) and 3) SDP (0.3% Scutellaria dry powder was used as the replacement of wheat in basal diet). No differences were found in antioxidant capacity and IgG concentration in plasma of sows among all the three treatments. Antioxidant capacity in colostrum was not affected by replacement of ginger and Scutellaria dry powder. IgG and protein concentration in colostrum was significantly higher (P<0.05) in GDP than that in CON and SDP. However, fat and lactose concentration were not affected by treatments. The total amino acid concentration in colostrum was significantly higher(P<0.05) in GDP than that in CON and SDP. Plasma antioxidant capacity was not affected by treatments in piglet on 0 day and 21 day, but tended to increase by supplementation of ginger. On 0 day, plasma IgG in piglet was not detected by replacement of ginger and Scutellaria dry powder. However, plasma IgG concentration in piglets on 21 day was significantly higher(P<0.05) in GDP than that in CON and SDP. These results indicate that colostrum IgG concentration in sows and plasma IgG concentration in piglets were improved by feeding ginger dry powder 30 days before farrowing in comparison to basal diet.
