The aim of this study was to establish the total fungal (mould) count in 79
commercial pig farm feed samples (42 samples for piglets, 29 samples for
fattening pigs and 8 samples for sows) collected from the Serbian feed
producers during the three-year period (2017-2019), as well as to evaluate
the percentage of contamination samples by fungi, especially species from
Aspergillus, Fusarium and Penicillium genera. Using standard mycological
methods, the total count and identification of fungi were determined. Total
fungal count was ranging from 1 ? 102 to 1.41 ? 105 cfu g-1 in the feed
samples for piglets. Furthermore, in the feed samples for fattening pigs it
ranged from1 ? 102 to 2.54 ? 105 cfu g-1, and from 1 ? 102 to 1.93 ? 105 cfu
g-1 in the feed samples for sows. It has established the impermissible limit
of total fungal count in 3.45% and 4.76% of a feed for fattening pigs and
feed for piglets, respectively. Statistical analysis of the total number of
fungi did not establish significant differences between the examined feed
groups. Fusarium species were present in the most feed samples for fattening
pigs (65.52%), followed by the feed for sows (62.50%) and piglets (47.62%).
Aspergillus species were determined in 59.52, 58.62 and 37.50% feed samples
for piglets, fattening pigs and sows, respectively. Penicillium species
contaminated the lowest percentage of feed samples for fattening pigs
(27.59%) and the highest percentage of feed samples for sows (37.50%). In a
small number of samples Alternaria, Mucor, and Rhizopus species were
identified. Based on these results, it can be concluded that the
investigation of fungal contamination is an important indicator of a
hygienic condition of feed intended for the nutrition of farm pigs. In
addition, the percentage of fungal contamination of the examined samples
indicates a potentially high risk to animal health. Due to that, a regular
mycological evaluation is necessary to assess nutritional quality as one of
the fundamental criteria for feed safety.
