Batch no. 5ARL002
Description: beige powder
Quantity and container: 60 g in one glass flask and 10 g in one glass flask
Date of receipt: 29 November 1995
Storage conditions: at room temperature

Test animals
- Species:
- guinea pig
- Strain:
- Dunkin-Hartley
- Sex:
- male/female
- Details on test animals and environmental conditions:
- TEST ANIMALS
- Number: 30 animals ( 15 males and 15 nulliparous and non-pregnant females)
Allocation of the animals to the groups on day-1, the animals were weighted and randomly allocated to two groups; a control group 1 consisting of ten animals (five males and five females) and a treated group 2 consisting of 20 animals (ten males and ten females).
- Source: Centre d'Elevage Lebeau, 78950 Gambais, France
- Age at study initiation: approximately three months old
- Weight at study initiation: 413 +/- 26 g for the males and 402 +/- 32 g for the females.
- Housing: housed individually in polycarbonate cages ( 48 cm x 27 cm x 20 cm) equipped with a polypropylene bottle. The housing conditions (temperature, relative humidity and ventilation) were checked monthly.
- Diet (e.g. ad libitum): free access to "106 diet".
- Water (e.g. ad libitum): Drinking water filtered by a F.G. Millipore membrane (0.22 micron)
Bacteriological and chemical analysis of the water and diet and detection of possible contaminants (pesticides, heavy metals and nitrosamines) are performed periodically. It was verified that no contaminants in the diet or water at levels likely to influence the outcome of the study were present.
- Acclimation period: at least five days before the beginning of the study.
- Identification of the animals: ear-tattoo
ENVIRONMENTAL CONDITIONS
- temperature: 21 +/- 2 °C
- relative humidity: 30 to 70 %
- light/dark cycle: 12h/12h
- ventilation: about 12 cycles/hour of filtered, non-recycled air.
