In trial 1, thirty 17-d-old Arbor Acres chicks were allotted to 5 treatments with 6 replicates per treatment. Chicks were reared in individual cages and fed diets without or with supplementing 200 ppm of different essential oil: (1) thyme (T); (2) cinnamon (C); (3) oregano (O) and (4) rosemary (R) for 20 days. In trial 2, thirty 27-d-old Ross chicks were allotted to 5 treatments with 6 replicates per treatment. Chicks were reared in individual cages and fed same diets as in trial 1 for 18 days. Daily feed intake, nutrient digestibility, pH and microbial counts of digestive tract contents were measured in trial 1 and 2. The combined results showed that dietary supplementation of R numerically improved daily feed intake. Supplementing different essential oil in diet improved fecal and ileal digestibility of total fatty acid and saturated fatty acid (P<0.01). Supplementing T, C and R in diet significantly improved fecal and ileal digestibility of protein and unsaturated fatty acid (P<0.05). Supplementing T, O and R in diet improved caecum lactobacillus counts (P<0.05). Supplementing C and R in diet increased caecum lactobacillus/coliforms (P<0.05). Supplementing different essential oil in diet did not affect pH of digestive tract contents, coliforms and lactobacillus+coliforms counts. In conclusion, supplementing EO, especially C and R, in diet effectively improved caecal microbial environment and nutrient digestibility of broiler chickens.
