| Abstract | This study was carried out to know the effect of adding the Iraqi probiotic (Lactobacillus acidophilus , Lactobacilli spp , Bacillus subtilus , Saccharomyces cervisa) , vitamins A and E to diet on some productive features and blood parameters of Ross broiler, An experiment of 42 days duration was conducted with a flock of 200 chick one day-old , The chicks were distributed randomly into four equal treatments (50) chicks per each treatment with two replicates (25) chicks per each as follow : T1 : Control group fed on basal diet only . T2: Fed on basal diet + probiotic (5 gm/ kg feed) . T3: Fed on basal diet + vitamin A (12000 IU /kg feed ) + vitamin E (300 mg/kg feed ) . T4: Fed on basal diet + probiotic (5 gm/ kg feed) + vitamin A (12000 IU /kg feed ) + vitamin E (300 mg/kg feed ) . The results were showed a significant improvement in averages of body weight , weight gain and feed conversion efficiency for the treatments : probiotic , vitamins A and E and the mixture (probiotic + vitamins A and E) comparative with the control , The results of weights (carcass , liver and gizzard ) showed significant increased for treatments of T2 , T3 and T4 comparative with the control , no significant difference were found among four treatments in weights of the heart , in addition there were no difference among(T2 , T3 and T4 ) in dressing percentage and mortality , the results showed a calculation increase for these treatments in the dressing percentage and a calculation decrease in the mortality percentage comparative with the control , were for treatments ( T2 , T3 and T4 ) impact in improving rates of RBC , PCV and Hb significantly or calculation comparative with the control , not differ of these three treatments in the rates of RBC and PCV, while T4 were gave a significant increase in blood haemoglobin concentration from T2 and T3 that did not appear significant difference between them . |
