3.1. Growth performance
Growth performance results are presented in Table 2.
Initial BW (39.470.70 g/chick) did not differ between groups prior to the assignment of the experimental diets.
On d 21 post-hatch, treatment showed a cubic trend on BW (Po0.07). No other differences were found on BW or ADFI. Treatment with clove product showed cubic effects on F:G on d 0 to 21 an d 21 to 35 (Po0.05 and Po0.01, respectively) being the lowest values found for doses of 100 and 200 mg/kg.
When treatments were removed from the diets in finishing phase (35–42 d) and all broiler chickens were fed control diet, no differences were found on growth performance.
No differences were found on digestibility of DM and OM among treatments.
