o:1532 Effect of Modified Clinoptilolite to Counteract the Deleterious Effects of Ochratoxin A on Egg Production and Quality en The objective of this study was to evaluate the efficacy of modified clinoptilolite as mycotoxins adsorbent in preventing negative effects of ochratoxin A (OTA) on egg production and egg quality of laying hens exposed to this mycotoxin. Forty-eight (n=48) laying hens (27 weeks old) were used in this study. The hens were randomly divided into six equal groups and were fed for 7 weeks with a standard diet in addition to: E-I group - 1 mg/kg OTA; E-II group 0.25 mg/kg OTA; E-III group 1mg/kg OTA + 0.2% of MZ; E-IV group 0.25 mg/kg OTA + 0.2% of MZ. MZ group of hens was fed with standard diets containing 0.2% of the adsorbent (MZ). The control group of hens was fed with standard diet, without any addition of OTA or MZ. The present study showed that laying hens fed with 1 mg/kg of OTA (E-I), had a significant decrease (p<0.05) of all performance parameters during the trial, while group fed with 0.25 mg/kg OTA have shown no adverse effects on egg production and egg quality. Addition of modified clinoptilolite (0.2%) to the diet containing the OTA, minimized these effects bringing values not significantly different from the control diet for most of the parameters. These findings clearly indicate the protective potential of modified clinoptilolite against the toxic effects of OTA in laying hens.
