The effects of dust in and around stables on the health of the human being is in the spotlight. Just as the effects of dust exposure on health and productivity of the animal in the stable has the attention.
The reason is that a strong increase is observed in non-specific lung problems associated with growth retardation, failure and increased antibiotic use in poultry and pigs.
Still the effects of dust and microbial constituents on health are poorly understood. Inhalation of (organic) substance leads to respiratory diseases and lung in humans. Lung problems seem more common in farmers than in other professional groups.
The aim of this PhD project is to determine the effect of concentration, particle size and specific components of dust in stable air on lung health and production of chickens.
In this project, the chicken is chosen as a model because
- many similar and also complementary expertise on immunological grounds by chicken is available
- it is a relatively cheap and handy animal
- increase in number of lung abnormalities in both broilers in poultry feed.
The result is newly developed research methods for the determination of the effect of substance concentration and composition of the lung health of the chickens. This developed expertise in the field of air quality in relation to lung health and production leads to subsequent assignments of Livestock, Meat and Eggs and the Dutch Organization for Scientific Research (NWO).
