- TEST ANIMALS
- Source: BRL, Biological Research Laboratories Ltd. Wolferstrasse 4, CH-4414 Fullinsdorf/ Switzerland.
- Age at study initiation: Males: 8 weeks; Females: 11 weeks.
- Weight at study initiation: Males: 227-242 g; Females: 194-217 g
- Housing: During acclimatization in groups of five in Makrolon type-4 cages with standard softwood bedding ("Lignocel", SchillAG, CH-4132 Muttenz). During treatment and observation individually in Makrolon type-3 cages with standard softwood bedding.
