title: Influence of infection with avian intestinal spirochaetes on the faeces of laying hens.
abstract: Laying hens of 20 weeks of age were infected with avian intestinal spirochaetes (isolate 1380). After 20 weeks it was found that most infected birds shed 10(7) or more spirochaetes/ml caecal faeces. Faecal dry matter content was not significantly influenced by the infection, but the amount of crude fat in the faecal dry matter increased by more than 25%.
