| Abstract | This experiment was conducted to evaluate the impact of dietary inclusion of probiotic mixture (B. subtilis and B. lieniformis), Coconut oil (CO) and Nigella sativa oil (NSO) or Black cumin oil (BCO) on productive performance, economic efficiency indicators and carcass characteristics of broiler chicks. For this purpose, 140 day-old broiler chicks (Cobb500) were weighed individually and assigned randomly into four treatments (T) 35 chicks in each, divided into five replicates of 7 chicks in each. (T1) control fed a basal diet, (T2) fed a basal diet + Coconut oil (10 ml/kg feed); (T3) fed a basal diet + Nigella sativa oil (1ml/kg feed) and (T4) fed a basal diet + bacillus probiotics (1g/kg of diet). Results clarified that CO, NSO and probiotic mixture groups improved significantly (P>0.05) the productive parameters (final body weight (FBW), body weight gain (BWG) and feed conversion ratio (FCR)) compared to control group. CO-based diet group recorded the highest BW and BWG, while probiotics mixture group was superior in feed intake value. The lowest FCR value was recorded in CO and NSO-based diet groups. The best economic efficiency measures were scored in CO followed by NSO then bacillus probiotics. Also, there are significant differences (P<0.05) among dietary treatments on relative weight of carcass, inner organs and immune organs. Diet containing NSO acquired the highest dressing percent (73.50%), while the highest relative weight of (heart, proventriculus, thymus, spleen %) was registered in broilers fed probiotics mixture diet. In conclusion CO, NSO, probiotics mixture-based diet has a beneficial influence on productive performance and economic indicators, thus highly recommended utilizing those supplements as natural feed additives. |
