- A preliminary study was performed to assess the effect of FR-370, when administered continuously via the diet, on the reproductive performance of rats. The study was not performed according to OECD 415 (one-generation reproduction toxicity study) but the study design was similar to OECD 421 (reproduction/developmental toxicity screening test), with the important exception that the F0 females were followed a considerable longer period than 4 days after delivery.

Details on results (P0)
generated average achieved intakes of approximately 160, 760
and 1590 mg/kg/day respectively for F0 males and 170, 905
and 1775 mg/kg/day respectively for F0 females before
pairing. Intakes by females were slightly higher through
gestation and reached peaks of 400, 1780 and 4110 mg/kg/day
at 2000, 10000 and 20000 ppm respectively during the second
week of lactation when food consumption was at its highest.
F0 generation animals showed no signs of adverse reaction to
treament and there were no deaths following administration
of FR-370 at dietary inclusion levels up to 20000 ppm.
Control bodyweight and cumulative bodyweight change were
higher than expected, compared with background data and were
above values in the treated groups throughout the entire
treatment period. There was no evidence of a dosage
relationship and intergroup differences were considered to
be unrelated to treatment. Group mean body weight and
bodyweight gain values for females before pairing and during
gestation and lactation were unaffected by treatment.
Food consumption for males and females in the four week
period before pairing and for females during gestation and
lactation were similar to respective Control values. Food
conversion efficiency was slightly lower for treated males
compared to the concurrent Control values, these were
considered to be of no biological importance.
There was no adverse effect of treatment upon pre-coital
interval, mating performance and fertility, gestation length
and gestation index.
Numbers of implantations, litter size, offspring survival
and sex ratio were unaffected by dietary administration of
FR-370. Offspring bodyweights to weaning were unaffected by
levels of FR-370 of up to 20000 ppm in the diet.
There were no consistent observations at necropsy of the F0
animals, offspring killed prior to scheduled termination,
and surplus of offspring killed after selection of the F1
generation, that were considered to be an adverse effect of
treatment with FR-370 in the diet.

Details on results (F1)
Dietary inclusion levels of 2000, 10000 and 20000 ppm
generated average achieved intakes of approximately 285,
1500, and 3040 mg/kg/day respectively, for selected males
during the first two weeks of the male F1 treatment period.
Average inatke for the two weeks of treatment for selected
F1 females receiving 2000, 10000 and 20000 ppm were 290,
1580 and 3095 respectively.
The general condition of the selected F1 animals in the
treated groups was similar to that of Controls and there
were no premature deaths in groups receiving FR-370.
At the start of the F1 generation (approximately 4 weeks of
age) group mean values of bodyweight for selected F1 animals
at 10000 and 20000 ppm were slightly lower than Control
values and remained lower than Controls throughout the F1
generation for the two week treatment period for females,
and the three week treatment period for males.
Group mean values of food consumption and food conversion
efficiency for selected F1 animals were similar to Controls
throughout the F1 generation treatment period and were
unaffected by treatment.
The timing of balano preputial separation for selected F1
males and of vaginal opening in F1 selected females were
considered to have been unaffected by treatment.
Macroscopic examination of selected F1 animals revealed no
consistent abnormalities which were considered to be related
to treatment with FR-370 at 2000, 10000 and 20000 ppm in
the diet.
Conclusion:
It was concluded that a dietary level of 20000 ppm would be
suitable as the highest dietary concentration for a main
multigeneration study in the CD rat. This equates to the
maximum dietary cocentration required by the EPA regulations
for a material where high human exposure is not predicted.
