Influence of probiotic and flaxseed oil supplementation on some physiological parameters and immune response of broilers

Abstract

The present research was aimed to study the effect of probiotic, flaxseed oil and their combination on some physiological traits and immune response of broilers. 200 one-day-old chicks (Ross 308) were randomly divided into four equal groups (50 of each) with two replicates. All the chicks were reared in farm of Veterinary Medicine College/ University of Baghdad for 42 days from 2 November 2016 up to 13 December 2016. The 1st group (control) fed on basal diet, 2nd group fed on basal diet with 0.5 gm probiotic /kg feed, 3rd group fed on basal diet with 2 gm flaxseed oil/kg feed and 4th group fed on basal diet with 0.5 gm probiotic and 2 gm flaxseed oil/kg feed. The results of the 4th groups recorded significant (P≤0.05) increase in RBC (2.03×103/ml), total protein (63.66 g/l) as compared with the 2nd, 3rd and control groups at aged 42 days. The results also showed significant reduction in cholesterol, triglycerides concentrations and H/L ratio of 3rd and 4th groups at the same time. In conclusion, dietary probiotic and flaxseed oil supplementation have improved the some hematological and biochemical parameters of broilers; also that mixture has enhanced the immune response to ND vaccine of treated chicks.
