The rearing and maintenance of breeding chickens in isolators: 2. Plastic tent isolators.

Plastic tent isolators for the rearing and maintenance of chickens from day-old to 80 weeks of age free from a number of pathogens have been evaluated. The use of individual ventilation units for each isolator has been compared with a central plant capable of supplying several isolators and has been found to be more efficient and have lower running costs.
