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).
