Associated efficiency of Saccharomyces cerevisiae and vitamin E in ameliorating adverse effects of ochratoxin on carcass traits and organ weights in broiler chickens

Abstract

The associated efficacy of Saccharomyces cerevisiae (SC) and vitamin E, in ameliorating ochratoxicosis (OTA) was investigated in broiler chickens. A total of 330 day-old broiler chicks were divided into eight treatment groups (T1-control; T2-T1+150 ppb OTA; T3-T2+0.05% SC+100 mg vit. E; T4-T2+0.075% SC+100 mg vit. E; T5-T2+0.1% SC+100 mg vit. E; T6-T2+0.05% SC+200 mg vit. E; T7-T2+0.075% SC+200 mg vit. E; T8-T2+0.1% SC+200 mg vit. E/kg diet. Each diet was fed to five replicated groups of 8 birds each from day-old to 42 days of age. At the end of sixth week of experimental trial, eight birds per dietary treatment were sacrificed to record carcass traits and relative weights of liver and immune organs. There was no significant (p<0.05) difference among various dietary treatments with regard to shrinkage loss, dressing yield and eviscerated yield, and cut-up parts of birds. The relative weight of liver in control group (T1) was significantly (p<0.05) lower than that of ochratoxin alone fed group (T2). The relative weight of liver in T5, T7 and T8 was significantly (p<0.05) lower than toxin fed group (T2) but statistically similar to that of control. The relative weight of thymus and bursa in groups T5, T7 and T8 was higher (p<0.05) than the toxin fed group (T2) and statistically similar to that of control (T1). It was concluded that addition of S. cerevisiae (0.1%) along with vit. E (100 mg/kg) or S. cerevisiae (0.075%) along with vit. E (200 mg/kg) in 150 ppb ochratoxin contaminated feed ameliorated the adverse effects of ochratoxicosis in broiler chickens.
