| This study evaluated a phytogenic feed additive for broiler chickens. A total of 1,632 broiler chicks were distributed into four treatments: negative control (without growth promoter); positive control (avilamycine, 10ppm + colistin, 15ppm); and two alternative treatments with 150ppm of phytogenic additive, one with a reduced Ca and P levels diet (PA-R1) and the other with lower energy, and amino acids, besides Ca and P (PA-R2). The trial was conducted with 12 replicates, each consisted of a pen with 34 birds. The alternative diets showed body weight intermediate to the two controls at 42 days, with no significant (P>0.05) treatment effect on feed conversion ratio. No treatment differences (P>0.05) on carcass yield and composition was observed. There... |

| ABSTRACT The present study was conducted to investigate the influence of different levels of dietary phytogenic feed additive (PFA) on growth performance, caecal microbiota, and intestinal morphology of broilers. A total of 480 Ross-308 one-day-old male broilers chicks (body weight 43±3 g) were randomly assigned to 32 replicate pens of four experimental groups, each experimental group consisting of 8 replicates (each replicate pen consisting of 15 chicks). A basal diet was formulated based on corn and soybean meal that was fed to the control group. Other dietary treatments received a commercial PFA at 100 mg/kg (PFA100), 125 mg/kg (PFA125), and 150 mg/kg (PFA150). Body weight gain, feed intake, and feed conversion rate of broilers were recorded on 1-21,... |
