Fig. 4. Concentration and chemical form of dietary zinc alter the antibiotic resistance gene abundance in the pig colon.

Fig. 4

Relative abundance of antibiotic resistance genes (given as number of aligned reads per 1000 bp of reference gene) identified in colon microbiomes of piglets (n = 6/group) fed diets with added zinc oxide at 40 ppm (40ZnO), 110 ppm (110ZnO), 2500 ppm (2500ZnO), or 110 ppm Zn-Lysinate (110ZnLys) over a period of 3 weeks. Individual gene abundance within each class of antibiotics is given in Supplementary Table S10.
