Values are means of 5 pens per treatment combination with 25 male broiler chickens
^a,b,cValues in the same row with different superscripts were significantly different (P < 0.05)
¹NTM, no trace mineral supplementation; ITM, commercially recommended levels of inorganic trace mineral; CTM25, chelated trace mineral supplement (CTM) match to 25% of the ITM; CTM50, CTM match to 50% of the ITM; CTM100, CTM equivalent to ITM
²Calculated as: liveability (%) × live weight (kg) × 100/age (day) × (feed intake/body weight gain)
