Summary: Between January 2010 and January 2017, 23 in vivo studies (comprising 50 trials) were published that evaluated the use of potential dietary feed additives (pDFA) against a positive control diet with antibiotics in weaned piglets, and reporting the performance parameters average daily gain’ (ADG) and ‘feed conversion ratio’ (FCR). The results of the meta-analysis clearly show that adding a pDFA at weaning can improve performance indicators compared to an untreated group (negative control), suggesting that pDFA could increase growth and improve feed conversion. As such, pDFA could potentially enhance production without the negative side effect of AMUs. Compared to the use of AMUs (positive control), the results of the meta-analysis show no overall significant difference. This is a beneficial result, as it suggests that the use of AMUs around weaning, a very commonly used practice, could be replaced by pDFA without significant negative effects on the performance indicators.
