- 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 0.96 m2/pig = 10 pigs/pen; 0.84 m2/pig = 12 pigs/pen; 0.72 m2/pig = 14 pigs/pen
- 3 Mean of the total number of body lesions counted at anterior, mid, posterior and total body regions on both sides of the body
