Feed contamination to fungi can
lead to nutrient losses and detrimental effects on animal health and
production. The aim of this study was to determine the mycoflora
incidence in poultry feeds during a two year
period. A total of 230 samples of poultry feeds in 2007 and 235
samples in 2008 were examined for total fungi count and the frequency of pathogenic
fungi genera. Total fungi count was 1–9 × 104 CFU g–1
in the most of investigated poultry feed samples (38.26% and 45.53% in 2007 and 2008, respectively).
In comparison of the average total fungi count in samples of poultry feed
from two investigation years no statistically significant differences
were established. The prevalent
fungi genera were Fusarium
(56.09 and 63.40%) and Aspergillus (54.35 and 73.62%),
followed by Rhizopus (40 and 62.98%), Penicillium (30.87
and 48.09%), Mucor (30.04 and 31.49%) and the least frequent
species were from the genus Alternaria, 3.48% and 17.02% in 2007 and 2008, respectively.
