Control: feed tables covered by paint without silver nanoparticles; AgNPs: feed tables covered by paint containing the silver nanoparticles; EM: feed tables sprinkled by the water-based solution of Effective Microorganisms; AgNPs + EM: feed tables covered by paint containing the silver nanoparticles and sprinkled by the water-based solution of Effective Microorganisms. The means with different superscripts (a, b, c and d) are significantly different (p < 0.05).
