Each value is the mean value of 6 replicates (4 pigs/pen).
CON, control diet based on corn and soybean meal; T1, CON + 0.1% heat-killed LR; T2, CON + 0.2% heat-killed LR; T3, CON + 0.4% heat-killed LR.
Means with different superscripts in the row differ (p ≤ 0.10).
BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; G:F, gain to feed ratio.
