“…Most dust, and its components, inside and outside of animal houses, originate from manure, bedding, skin, feathers, and feed (Welch, 1986;Takai et al, 1998;Aarnink et al, 1999;Cambra-Lopez et al, 2011). The concentration and composition of dust var-ies due to animal activity, species, age, light schedule, ventilation, stocking density, and house design (Collins and Algers, 1986).…”

We studied the effects of a concurrent challenge on slow-growing broilers with 1) airborne particles of 2 sizes: fine dust (smaller than 2.5 microns) and coarse dust (between 2.5 and 10 microns) that were directly collected from a broiler house and 2) lipopolysaccharide on intratracheal immunizations with the specific antigen human serum albumin (HuSA) and measured primary and secondary systemic (total) antibody responses and (isotype-specific) IgM, IgG, and IgA responses at 3 and 7 wk of age. All treatments affected immune responses at several ages, heart morphology, and BW gain, albeit the latter only temporarily. Dust particles significantly decreased primary antibody (IgT and IgG) responses to HuSA at 3 wk of age but enhanced IgM responses to HuSA at 7 wk of age. Dust particles decreased secondary antibody responses to HuSA, albeit not significantly. All of the birds that were challenged with dust particles showed decreased BW gain after the primary but not after the secondary challenge. Relative heart weight was significantly decreased in birds challenged with coarse dust, fine dust, lipopolysaccharide, and HuSA at 3 wk of age, but not in birds challenged at 7 wk of age. Morphology (weight, width, and length) of hearts were also affected by the dust challenge at 3 wk of age. The present results indicate that airborne dust particles obtained from a broiler house when intratracheally administered at an early age affect specific humoral immune responsiveness and BW gain of broilers to simultaneously administered antigens differently than when administered at a later age. The hygienic status of broiler houses at a young age may be of importance for growth and immune responsiveness, and consequently, for vaccine efficacy and disease resistance in broilers. The consequences of our findings are discussed.

“…By scratching, dust-bathing and other activities, dust particles are formed, especially from manure and feathers (Cambra-Lopez et al, 2011), and suspended in the air. In layer houses with battery cages, where no litter is present, and where there is no contact between animals and their manure, a lot lower dust concentrations were reported .…”

“…It should be noted that when calculating particle mass distribution from particle count distribution we assumed that the density of the particles was 1 mg mm -3 and that the particles had a spherical shape. Both can vary, depending on the source of dust (Cambra-Lopez et al, 2011) and probably also depending on the way the dust is generated. While we do not know the contribution of each dust source to the particles in the different size ranges, we made these simple assumptions for density and shape.…”

“…In meatand laying poultry production systems, air quality can be affected by high dust concentrations (Le Bouquin, 2019), which can cause health problems in employees and animals (Cambra-Lopez, 2011). Diseases induced by inhalation of different bioaerosols are related not only to their biological properties and chemical composition, but also to the number of inhaled particles and the place where they deposit in the respiratory system.…”

“…Bird sheds are environments that can generate excessive dust, which originates from the bed, fiberglass insulation materials, food, dry fecal materials and feather particle (Cambra-Lopez et al, 2011). Dust can contain microorganisms, including endotoxins, fungi and bacteria, which can affect living beings when inhaled, (Wang & Ogawa 2015) with dust containing living organisms referred to as bioaerosol and its particle can range from 0.5 to 100 μm.…”

As dust particles in laying poultry houses can have negative effects on health and on the environment,this study aimed to measure and compare dust concentrations in egg production sheds. The experiment was carried out in three sheds: Californian shed (G1), conventional closed shed with artificial ventilation (G2) and conventional closed shed without artificial ventilation (G3), and the birds housed were in the 22nd week of housing, in Cuité, Paraíba, Brazil.The dust particles were collected by a gravimetric pump, attached to the workers' clothes, at the height of the respiratory zone, being removed at the end of the working day. Using the evaluation methodologies (total or breathable dust) according to NIOSH (1998), weighing was performed with sample concentration calculation, then the particle size was measured by microscopy according to the methodology described by Feret(Santos, 2001), with diameter of function obtained using an optical microscope, and particles classified by size (inhalable <100 μm, thoracic <25 μm and breathable <10 μm).Considering the limit of concentration x exposure time of 3.0 mg/m3, according to ACGIH (2013), the sheds had the following values: G1-0.98 mg/m3, G2-1.45 mg/m3 and G3-1.13 mg/m3. In the classification of particles by size, the highest frequencieswere 83% thoracic, 13% inhalable, and 4% breathable.With the results presented, the implementation of the Respiratory Protection Program - PPR is suggested.
