The test substance solutions in corn oil were prepared at the beginning of the administration period and thereafter in intervals, which took into account the analytical results of the stability verification. - Analytical verification of doses or concentrations:
- yes
- Details on analytical verification of doses or concentrations:
- Analytical verifications of the stability of the test substance in corn oil for a period of 7 days at room temperature were carried out prior to the start of the study.

Examinations
- Maternal examinations:
- CLINICAL OBSERVATION:
Morbidity, pertinent behavioral changes and signs of overt toxicity. Abnormalities and changes were documented daily for each animal.
The parturition and lactation behavior of the dams was generally evaluated in the mornings in combination with the daily clinical inspection of the dams.
BODY WEIGHT:
Body weight of the male and female parental animals was determined once a week at the same time of the day (in the morning) until sacrifice.
The following exceptions are notable for the female animals:
• During the mating period the parental females were weighed on the day of positive evidence of sperm (GD 0) and on GD 7, 14 and 20.
• Females with litter were weighed on the day of parturition (PND 0) and on PND 4.
FOOD CONSUMPTION:
Food consumption was determined once a week for male and female parental animals:
• Food consumption was not determined after the 2nd premating week (male parental animals) and during the mating period (male and female F0 animals).
• Food consumption of the F0 females with evidence of sperm was determined on gestation days (GD) 0, 7, 14 and 20.
• Food consumption of F0 females, which gave birth to a litter was determined on PND 1 and 4. - Ovaries and uterine content:
- The ovaries and uterine content was examined after termination: Yes
Examinations included:
- Number of implantations: Yes - Fetal examinations:
- All pups delivered from the F0 parents (F1 litter) were examined as soon as possible on the day of birth to determine the total number of pups, the sex and the number of liveborn and stillborn pups in each litter. At the same time, the pups were also being examined for macroscopically evident changes. Pups, which died before this initial examination, were defined as stillborn pups.
PUP VIABILITY/MORTALITY
In general, a check was made for any dead or moribund pups twice daily.
CLINICAL OBSERVATION
The live pups were examined daily for clinical symptoms.
BODY WEIGHT
The pups were weighed on the day ater birth (PND1) an on PND 4.
All pups with scheduled sacrifice on PND 4. All pups were examined externally and eviscerated; their organs were assessed macroscopically. - Statistics:
