Figure 1. Effect of P, SS, and SP on the relative mRNA levels of (A) Gpx1 and (B) Gpx4 in the liver of broiler chickens, feeding a basal diet (Con), basal diet plus P, basal diet plus SS, and basal diet plus SP. Each bar represents mean of 10 samples in a group and standard error. The values with unlike superscript letters (a, b, c) in the figure represent different levels of significance at p < 0.05.
