The EO blend and LA in drinking water significantly (P < 0.05)
reduced SH colonization in crops of seeders and contacts; whereas
EO, increased significantly weight gain, and reduced mortality in
broilers compared to all other treatments. The other nonpharmaceutical
compounds used in this study significantly
(P < 0.05) reduced the percentage of crops infected with SH
compared to those of controls. Additional studies are needed to
determine the optimum and most effective concentration of the
essential oil blend in water to reduce colonization and fecal shedding
of SH in broilers.
