  1. 1 Body weight (BW), average daily gain (ADG), average daily feed intake (ADFI), feed conversion ratio (FCR) and body lesion counts from 216 grower-finisher pigs (6 pens/treatment; Least square means ± Standard error mean [SEM]) from 10 to 20 weeks of age, when the first group of pigs reached 110 kg of BW and were sent to slaughter
  2. 2 0.96 m2/pig = 10 pigs/pen; 0.84 m2/pig = 12 pigs/pen; 0.72 m2/pig = 14 pigs/pen
  3. 3 Mean of the total number of body lesions counted at anterior, mid, posterior and total body regions on both sides of the body
  4. a,b Within rows, significant differences between groups (P <  0.05)
