Use of some physical and biological treatments to suppress the effects of aflatoxin B1 on blood and immune traits of broiler

Abstract

This study aimed to evaluate the use physical adsorbents (Bentonite and Activated Charcoal)and biological treatments to reduce the deteriorative effects of aflatoxinB1 (AFB1) contaminated broiler diet with 2mg/kg .144one day old broiler were randomly allocated to 8 treatments . T1:Control diet. T2: Contaminated diet with 2mg/kg AFB1. T3: Contaminated diet + Prebiotic ( 5gm / kg ). T4: Contaminated diet + Iraqi probiotic ( 5 gm / kg ) . T5: Contaminated diet + Bentonite ( 1% ).T6: Contaminated diet + Activated charcoal ( 1%). T7: Contaminated diet + Foreign probiotic ( 5 gm /kg). T8: Contaminated diet + Synbiotic ( 5 gm / kg ).the results showed that, AFB1with diet caused an increase in lymphocyte to heterophillus ratio compared to control,and decreased the relative weight of bursa of fabricius, also AFB1 caused significant reduction in immunoproteins and 123ewcastle antibodies titer. Results of physical and biological treatments showed significant Improvement in traits .The different treatments reduced significantly, the stresses caused by AFB1as was manifested by the decrease of lymphocyte to heterophiles ratio . in addition to the positive effect in immunoproteins (γ globulin, albumin ,transpherin), an increased in 123ewcastle antibodies titer and relative weight of bursa of fabricius
