Details on test animals or tissues and environmental conditions:
Three male and three female New Zealand White rabbits {order weight 2.5 kg-3.0 kg) were used in the test. They were supplied by Reputable Commercial supplier and arrived on 24 February 1987. They were fed Special Diet Servfces Rabbit Diet of satisfactory analysis and allowed food and water ad libitum. They were housed individually in aluminium cages with grid floors beneath which were peat moss fi11ed trays. A 12 h light/dark cycle was in operation.
Mean environmental maximum and minimum temperatures were 17°C and 16°C and mean relative humidity was 58%.
The animals were allowed an acclimatisation period of 8 days before test commenement.
