A total of 105 [(Landrace × Yorkshire) × Duroc] pigs with an initial body weight (BW) of 7 ± 1.58 kg were used in a 5-week experiment in two phases to test the efficacy of supplementation of chelated mineral mixture on piglet performance. Pigs were randomly allocated to one of three treatments [five pigs per pen (three barrows and two gilts); seven pens per treatment]. Treatments consisted of: CON; basal diet, TRT1; basal diet + 0.89% chelated mineral mixture and TRT2; basal diet + 0.55% chelated mineral mixture. Pigs fed TRT1 and TRT2 had increased (P < .05) gain/feed ratio during the first phase and overall and had greater (P < .05) average daily gain (ADG) during the second phase compared with CON. Pigs fed TRT1 had greater (P < .05) ADG overall and had higher (P < .05) dry matter (DM) digestibility during the first phase. On day 35, the concentrations of Fe and Cu in blood serum were higher (P < .05) in TRT1 and TRT2 but Ca concentration increased (P < .05) and faecal Escherichia coli counts reduced in TRT1 compared with CON. In conclusion, our results indicated that chelated mineral mixture have beneficial effects in pigs.
