My experience with multiple applications of PLT during a flock’s growth cycle has produced both good and bad results. The “good” result has been a direct correlation with increased weights from the treated houses, when compared to non-treated houses. Performance in general has also been much better overall from continuously treated houses, compared with traditional brood-chamber-only applications. The lack of ammonia decreased our ventilation requirements and saved fuel costs.
That lack of ammonia relates to our “bad” results. Unfortunately for our test houses, growers reduced ventilation rates dramatically due to lack of ammonia. That reduction in fan time allowed humidity to build up and the houses got wet. Once that happened, paw quality deteriorated and excessive cake developed.
On farms where the growers ventilated more for humidity than ammonia, cake was not an issue and paw quality was satisfactory. If growers maintain proper air quality with multiple PLT applications and ventilate more for humidity, performance on all parameters would improve.
