Applicant's summary and conclusion
- Conclusions:
- Based on the findings in the study, the no adverse effect level (NOAEL) for parental and developmental toxicity was established as more than 1000 mg/kg/day.
- Executive summary:
Parental Data:
Adult males and females tolerated Hypersol Synergist L4722 at oral doses levels up to and including 1000 mg/kg/day without changes to appearance and behaviour, and without effect on survival, body weight or food intake.
There were no treatment-related macroscopic or microscopic lesions detected in parental animals.
Reproduction and litter data:
The result of the study indicate that mating was successful in all groups with similar mean coital times recorded for all groups. there was no indication of any treatment-related effects on fertility, since fertility and conception rates were similar for treated and control groups. Gestation times were unaffected by treatment.
The viability of the pups was not influenced by treatment. Development of pups from treated dams progressed in a similar manner to those pups from control dams i.e. no treatment-related clinical signs were observed and body weight development was similar for treated and control litters. Macroscopic examinations of the pups at necropsy did not detect any lesions that were associated with exposure of the parents to Hypersol Synergist L4722.
Based on the findings in the study, the no adverse effect level (NOAEL) for parental and developmental toxicity was established as more than 1000 mg/kg/day.
