Two independent trials were conducted to assess the effect of Herbanoplex CP (HB) on broiler chicken's performance using a 1) a nondefined challenge or 2) necrotic enteritis (NE) challenge model with intestinal lesion scoring. Herbanoplex CP is a unique combination of phytocompounds (ground hops, wheat germ, and chicory). In Exp 1, 400-day-old male chicks (Cobb 500) were individually tagged, weighed, and randomly assigned to one of 20 pens (n = 20 birds/pen). Pens were randomly assigned per treatment group: 4 treatments with 5 replicates each (n = 100 birds/treatment). T1: no modification; T2: antibiotic growth promoter bacitracin methylene disalicylate (BMD) 11% at 0.5 kg/metric ton); T3: HB 1 kg/metric ton; and T4: HB at 0.5 kg/metric ton. On day 7, 14, 15 of life, all birds in all treatment groups were challenged by drinking water with a liter filtrate as a nondefined challenge model. Their performance was evaluated at day 35. T3 had a significant (P-value
