Abstract
In this study, mannan-oligosaccharide (MOS) and vitamin E (Dl-α-tocopheryl acetate) were used as feed supplements to ameliorate the deleterious effect of Ochratoxin-A (OTA) on laying hens productive performance, some blood constituents  and egg quality. A total of 180 Inshas hens, 28 weeks of age were randomly distributed according to diet supplementation into six groups (30 hens each) as follow. T1: fed a hen diet without any supplementation (control) ; T2: fed the control diet supplemented with 1 g MOS / kg diet; T3: fed the control diet supplemented with 150 mg Vit.E / kg diet; T4: was fed the control diet contaminated with 1000 ppb of OTA. While, T5: fed the control diet contaminated with 1000 ppb OTA and supplemented with 1 g MOS / kg diet; T6: fed the control diet contaminated with 1000 ppb OTA and supplemented with 150 mg Vit.E / kg diet. Results showed that feeding OTA at 1000 ppb (T4) significantly decreased egg production percentage and feed consumption. Moreover, a significant increase in relative weights of kidney and liver, in addition to high mortality percent and worse feed conversion ratio were observed in OTA-fed birds. On the other hand, addition of either MOS or Vit E ameliorate the toxic effects of OTA.
