^aA total of 289 finishing pigs (DNA 241 × 600; initially 54 kg) were used with 6 replicate pens per treatment and 8 to 14 pigs per pen. Research was conducted at Texas A&M University, O.D. Butler Animal Science Teaching and Research Center, Nutrition and Physiology Center (College Station, TX).

^bThree phases of experimental diets were fed from d 0 to 19, d 19 to 36 and d 36 to 53 for Phases 1, 2 and 3, respectively.

^cResults from experiment were considered significant at P < 0.05 and a marginal significance between P > 0.05 and P ≤ 0.10.

^d–fPhases contain increasing amounts of LL (SweetLac 63; Westway Feed Products, Tomball, TX).
