Fig. 2From: Mammary inflammatory gene expression was associated with reproductive stage and regulated by docosahexenoic acid: in vitro and in vivo studiesConcentration of α-tocopherol and MDA in serum of sows at different reproductive stages. Serum Concentration of α-tocopherol(a) and MDA(b) was determined with commercial kits with serum samples obtained at day 90 of gestation, parturition and day 28 after parturition. Values are presented as means ± SE. Statistics with no common letters differ significantly (P < 0.05)Back to article page
