Abstract:
The purpose of this study is to investigate the influence of dietary inclusion of Cordyceps or essential oils or together on the growth response and carcass characteristics of broilers. A commercial diet without antibiotic was served as negative control (T1) and with added antibiotic served as positive control (T7). Five test diets were prepared by supplementing commercial diet with Cordyceps @ 50g/kg (T2) and 100g/kg (T3), essential oils @ 125g/kg (T4) and 250g/kg (T5), Cordyceps @ 50g/kg and essential oils 125g/kg (T6). Each diet prepared for pre-starter (0-14 days), starter (15-28 days) and grower (29-42 days) was offered to triplicate groups of 10 day old straight run commercial chicks each. The body weights of birds were significantly higher in group fed diet supplemented with Cordyceps and essential oils together with better feed conversion efficiency. The carcass characteristics study at the end of 42 days trial revealed that the non-significant (P >0.05) differences in dressing percentage, thigh and breast meat and bursa (g/100g live wt.) except gizzard among different groups. The inclusion of Cordyceps and essential oils together in the diet has beneficial effects on growth performance of broilers.
