The influence of lactic acid bacteria powder compared with antibiotic on carcass characteristics was assessed at 42 day of age in broiler chickens. Two-hundred (1-d old) mixed-sex broilers were assigned to 4 dietary treatments: T1) Control diet, T2) Control + 0.05% of Oxytetracycline, T3) Control + 0.2% of Lactobacillus plantarum ST1 powder (Single strain), and T4) Control + 1.0% of fermented juice of epiphytic lactic acid bacteria powder (Mixed strain). The experiments were assigned using Completely Randomized Design (CRD; 5 reps/trt and 10 birds/pen). Each treatment was provided in a 2-stage feeding program (Starter; 22% protein and Grower; 21% protein). Supplementation with either single or mixed-strain of lactic acid bacteria powder, and with... |
