2No. pens/trt = pen replicates per treatment; five pigs per pen replicate
3CV, coefficient of variation as a measure of within pen pig weight variation.
4Carcass ADG: From weight at start of experiment to slaughter = ((carcass weight in kg – BW on day 1 × 0.75) x 1,000) / number of days on treatment (Lawlor and Lynch, 2005). A higher kill-out percentage was used in exp. 2 due to the heavier BW on day 1.
5Carcass FCE: From start of experiment to slaughter = total average daily feed intake / carcass ADG (g).
