Influence of infection with avian intestinal spirochaetes on the faeces of laying hens.
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%.
