Antibiotic or Feed Additives for Nursery Pigs  Pharmacological Cu, Zn and CTC consistently improved ADG and ADFI.  Due to their additive benefits, pharmacological Zn and CTC could be included together in diets to get the maximum benefit in growth performance of weaned pigs.  Neither pharmacological Cu nor Zn improved feed efficiency.  Origanum essential oil elicited no growth benefits and worsened G:F.  There were minimal carryover effects from any of these dietary treatments on subsequent nursery growth performance. Feldpausch et al., 2015

Effects of Dietary Cu, Zn, and Ractopamine HCl on Finishing Pig Growth Performance, Carcass Characteristics, and Antibiotic Susceptibility of Enteric Bacteria Feldpausch et al., 2015

Added Cu, Zn and Ractopamine in Finishing Pigs  Dietary inclusion of 10 ppm ractopamine HCl for 28 d prior to marketing in heavy weight pigs dramatically improved carcass leanness as well as the feed and caloric efficiencies.  Addition of 125 ppm Cu (CuSO 4 ) or 150 ppm Zn (ZnO) above basal premix TM levels in diets containing ractopamine HCl did not improve finishing pig growth or carcass performance.  Over time, resistance to most antibiotics decreased or remained low for those with low baseline percentages.  Extended feeding of 125 ppm CuSO 4 thru finishing period sustained Enterococcus spp. resistance to a few antibiotics.  No adverse effects of Ractopamine HCl or 150 ppm added ZnO on antimicrobial resistance among bacterial isolates observed.
