In
spite of the need for a permanent minimum dust environment
for horses suffering from chronic obstructive pulmonary disease
(c.o.p.d.), many owners fail to maintain suitable long term
management regimes and many affected animals continue to show
signs of respiratory dysfunction. One reason for this is the
unpopularity of low dust feeds and bedding materials among
horse owners. To assess its suitability for use with c.o.p.d.
horses, the airborne dust level and concentrations of common aeroallergens
in a new commercial cardboard bedding product were measured
in vitro using a Ripon particle counter and an Anderson sampler,
respectively (Vandeput et al.1997). Data was compared to values
obtained from more traditional forms of bedding, ie woodshavings
and straw, using the same techniques. Total airborne dust concentration
and concentrations of Aspergillus fumigatus, Faenia
rectivirgula and Thermoactinomyces vulgaris in the cardboard bedding were significantly lower than those
of wood shavings and straw.
This study suggests that, due to its low concentration of airborne
dust and aerollergens, cardboard bedding may be useful in the
provision of minimum dust management for horses with c.o.p.d.
This is an extract from the table of data produced by University
of Liege Belgium when using EcoBed. Respirable
dust particles by litre of air and viable spore concentrations
(colonies forming units (cfu)) in 1.5 cubic
foot of air of Aespergillus fumigatus (A. fumigatus), Faenia
rectivirgula (F. rectivirgula) and Thermoactinomyces
vulgaris (T. vulgaris) in different types of bedding and supplement
(Mean ± standard deviation).

As you can see EcoBed had the lowest dust particles by litre
of air and viable spore concentrations.
In layman’s terms it is proven to be virtually dust and
spore free.
