Effect of modified clinoptilolite to counteract the deleterious effects of Ochratoxin A on egg production and quality

OBJECTIVE

The objective of this study was to evaluate the efficacy of modified clinoptilolite as a mycotoxin adsorbent in preventing the negative effects of ochratoxin A (OTA) on egg production and egg quality of laying hens exposed to this mycotoxin.

MATERIALS & METHODS

48 laying hens (27 weeks old) were used in this study. The hens were randomly divided into six groups and were fed for 7 weeks with the following combinations:

E-I group : standard diet + 1 mg/kg OTA
E-II group : standard diet + 0.25 mg/kg OTA
E-III group : standard diet + 1mg/kg OTA + 0.2% of Minazel Plus^®
E-IV group : standard diet + 0.25 mg/kg OTA + 0.2% of Minazel Plus^®
E-V group: diet + 0.2%+ Minazel Plus^®
Control group de control: standard diet

RESULTS

This 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 the group fed with 0.25 mg/kg OTA showed no adverse effects on egg production and egg quality.

The addition of modified clinoptilolite (0.2%) to the diet containing the OTA, minimized its 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.
