Abstract:
The current study was conducted to evaluate the effect of aromatic oils Grow-Nat(eucalyptol, oregano, thyme) on growth performance of broilers. The aromatic oils were supplemented in drinking water at three different levels (0, 0.25 and 0.5ml/L) during the period from day 10 to day 44 (i.e. 5 weeks). A total of 120 day old chicks (Hubbard F15) were allocated as complete randomized designin three treatment groups, each group was replicated 4 times each of 10 birds (3×4×10) (treatments X replicates X birds).Two nutritionally adequate diets were formulated according to (NRC, 1994). feed and water were provided adlibtum to meet the nutrient requirements of broiler chicks. Three levels of diets were fed prestarter (0-5 day), starter (6 -21 day) and finisher (22-44 day). The supplementation of aromatic oils revealed no significant differences in feed intake (FI), body weight gain (BW), feed conversion ratio (FCR), protein efficiency ratio, production efficiency factor and energy efficiency ratio among treatments.
