Test System Species: Dunkin Hartley strain, albino guinea pig (SPF-quality); recognised by international guidelines as the recommended test system (eg, OECD, EC). Source: Charles River Deutschland, Kisslegg, Germany. Number of animals: Experimental group: 10 females; Control group: 5 females (all females were nulliparous and non-pregnant). Age: Young adult animals (approximately 4 weeks old) were selected. Identification: Ear tattoo. Reliability check: The results of a reliability test performed not more than 6 months previously are given in the Appendix to the test report. Similar procedures were used in the reliability test and in this study.
Animal husbandry Conditions: Animals were housed in a controlled environment, in which optimal conditions were considered to be approximately 15 air changes per hour, a temperature of 21±3 °C (actual range: 19.3-21.8 °C), a relative humidity of 30-70% (actual range: 45-91%) and 12 hours artificial fluorescent light/12 hours darkness per day. Accommodation: Group housing of maximally 5 animals per labelled cage (74 cm x 54 cm x 25 cm height) containing sterilised sawdust as bedding material (Woody-Clean type 3/4;
Tecnilab-BMI BV, Someren, The Netherlands). analysis were examined and retained in the
NOTOX archives. The acclimatisation period was at least 5 days before the start of treatment under laboratory conditions. Diet: Free access to standard guinea pig diet including
