Use of yeast (Pichia kudriavzevii) as a novel feed additive to ameliorate the effects of aflatoxin B 1 on broiler chicken performance

The aim of this study was to evaluate the efficacy of autochthonous Pichia kudriavzevii as a novel bioadsorbent for aflatoxin B (AFB ). The selection of this yeast was based on the AFB adsorption capacity previously demonstrated in vitro (Magnoli et al. 2016). One-day-old Cobb broilers (n = 160) wer...

Description
Summary:The aim of this study was to evaluate the efficacy of autochthonous Pichia kudriavzevii as a novel bioadsorbent for aflatoxin B (AFB ). The selection of this yeast was based on the AFB adsorption capacity previously demonstrated in vitro (Magnoli et al. 2016). One-day-old Cobb broilers (n = 160) were randomly assigned to four dietary treatments (T1: basal diet (B); T2: B + 0.1% yeast; T3: B + AFB , 100 μg/kg; T4: B + 0.1% yeast + AFB , 100 μg/kg). Performance parameters (average daily weight gain body, average daily consumption, feed conversion ratio, carcass weight, and dead weight), biochemical parameters (albumin, globulin, and albumin/globulin), liver pathological changes, and AFB residual levels in the liver and excreta were evaluated. Significant differences (P
