用于保持家禽群“无病”的FAPP通风系统适用于肉鸡育雏。在FAPP条件下将一日龄的商品肉鸡小鸡孵育8至28天，然后与它们的孵化对照一起放置在常规圈养的田间。在FAPP条件下孵育18至21天的鸡在屠宰时的总死亡率比常规饲养的孵化物低约2%。这种减少主要是由于白血病的发病率较低，在肉鸡中，白血病现在被认为几乎完全是马立克氏病。如果我们最终走向消灭马立克氏病和其他空气传播的家禽疾病的计划，FAPP住房系统将成为我们最有用的工具之一。
The FAPP ventilating system used to maintain "disease-free" poultry flocks was adapted to brooding of broiler chicks. Day-old commercial broiler chicks have been brooded under FAPP conditions for 8 to 28 days before placement in the field in conventional housing with their hatchmate controls. Chickens brooded under FAPP conditions for 18 to 21 days had approximately 2% less total condemnations at slaughter compared to conventionally housed hatchmates. Most of this reduction was due to lower condemnations for leukosis which in broiler chickens is now considered almost entirely Marek's disease. If we eventually move toward an eradication program for Marek's disease and other airborne diseases of poultry the FAPP housing system will become one of our most useful tools.
