A 52-day pen trial on 10.2 cm built-up litter topped with pine shavings used a randomized complete block design (Tukey’s HSD p≤0.05). A total of 2,160 Cobb male chicks were randomly assigned to 48 pens (12 blocks) at 45 chicks/pen providing 0.0771 m2 per chick. Four phase feeds were used (0-17, 17-31, 31-42, and 42-52 days). Salinomycin (66.14 mg/kg) and 3-Nitro® 20 (50.0 mg/kg) were added from 0-31 days. Dietary treatments were: 1) negative control (nCON); 2) BMD® at 55.12 mg/kg 0-31 days, Stafac® at 22.05 mg/kg 31-52 days (AGP); 3) Actigen® (ACT) at 400 mg/kg; and 4) BMD® at 55.12 mg/kg 0-31 days, Stafac® at 22.05 mg/kg 31-52 days plus Actigen® (ACT) at 400 mg/kg (AGP+ACT). From 0-17 days, feed conversion ratio (FCR; p=0.026) and mortality-adjusted FCR (MAFCR; p=0.027) were lower for AGP and AGP+ACT than nCON, with ACT intermediate and statistically separate from other groups. At 31 days, body weight (BW; p=0.043) was greater for AGP+ACT than nCON, with AGP and ACT intermediate. From 0-31 days, FCR (p<0.001) and MAFCR (p<0.001) were lower for AGP, ACT, and AGP+ACT than nCON. At 42 days, BW was greater (p=0.006) for AGP and AGP+ACT than nCON, with ACT intermediate. The 0-42 day FCR (p=0.002) and MAFCR (p=0.006) were lower for AGP and AGP+ACT than nCON, with ACT intermediate. At 52 days, BW were greater (p<0.001) for AGP, ACT, and AGP+ACT than nCON. From 0-52 days, FCR (p<0.001) and MAFCR (p<0.001) were lower for AGP+ACT than nCON, with AGP and ACT intermediate, and mortality percent was lower (p=0.096) for AGP+ACT than nCON, with AGP and ACT in between. Based on performance, Actigen® at 400 mg/kg was statistically equivalent to BMD®/Stafac® from 0-52 days and BMD®/ Stafac® plus Actigen® was the most effective treatment.
