Disease control beyond the medication period ensures a positive effect on performance. In the same study, with a single application of ECONOR post-weaning, Alexopoulos demonstrated a statistically different feed conversion and average daily gain post-medication compared to a positive control group, resulting in an improved cost benefit (next below).
