Extract

Avilamycin (antibiotic growth promoter) and zinc oxide are both included in the diets of newly weaned piglets to enhance growth performance and reduce the incidence of diarrhoea (MLC, 2000). It is thought that both compounds positively influence the bacterial populations residing in the gastrointestinal tract. However, growing concerns regarding antibiotic resistance and environmental pollution are likely to result in the banning of these dietary additives within the EU. This experiment, therefore, aimed to investigate what effect removing both avilamycin and zinc oxide from the post-weaning diet would have on the growth performance of weaned piglets.
