The aim of this study was to investigate the efficacy of Sangrovit((R)), a plant-derived feed additive, given throughout the nursery stage via feed at 15ppm and 50ppm, on the health status and performance of weaners against negative controls. In a 900-sow farrow-to-finish farm, a total of 864 piglets were divided into three groups: (i) negative controls (NC); (ii) Sang 15: same feed as NCs, plus 15g Sangrovit((R)) /t of feed; (iii) Sang 50: same feed as NCs plus 50g Sangrovit((R)) /t of feed. The results indicated that administration of 50ppm(-)Sangrovit((R)) had the most beneficial effects on growth performance in weaning pigs. Specifically there was increase of body weight and average daily gain, as well as reduction of feed conversion ratio. Blood analysis from the Sang groups and especially the Sang 50 group revealed low values of haptoglobin and serum amyloid A.
