FPD

“Non-nutritional” factors that affects litterquality and ammonia production

Control of moisture and temperature -Bedding type quality -Cleanliness and desinfection between flocks -Days of interval between flocks -Stock density -Sanitary problems (Intestinal health - diarrhea)

-Equipment (Drinkers, coolers, etc..) -

Non nutritional factors that affects litterquality and ammonia production

Moisture and temperature

Moisture with high temperatures promote bacterial growth –decomposition of organic material – AMMONIA PRODUCTION.

AMMONIA – Caustic effects (burn), dermatites, keratoconjuntivitis(blindness), respiratory deseases, gastroenteritis, etc..

FPD scores of Dutch broiler > 2000 Barns in 2013. There is a seasonal effect and > 30% of the Dutch Barns still have problems

with FPDBarns with FPD > 120 have to lower the density from 42 kg to < 39 kg m2Farms between 80 and 120 point have to make a plan on how they plan to

improve the situation
