- Analyses were conducted on a single occasion during the treatment phase (18 February 2015). The concentrations analyzed in the formulations were in agreement with the target concentrations (i.e. mean accuracies between 85% and 115%). The formulations of the high and low dose groups were assessed for homogeneity and were found to be homogenous. Formulations were stable at room temperature for at least 6 hours.

Females were sacrificed after at least 4 days of lactation and were treated continuously up to the day prior to necropsy with the exception of three females which were left untreated for one day because they littered during the treatment time.

OTHER:
- pup mortality was determined on day 1 of lactation and daily thereafter.
- cliinical signs for pups were recorded at least once daily
- sex was determined for all pups on days 1 and 4 of lactation - Postmortem examinations (parental animals):
- yes, see section 7.5.1 (repeated dose toxicity)
- Postmortem examinations (offspring):
