“…Similar to that, Marković et al (2005) and Pleadin et al (2012) have also reported that Penicillium species were the most common in analysed feed samples. Furthermore, according to the reports of Almeida et al (2009) in Portugal and Pereyra et al (2011) in Argentina, Fusarium, Aspergillus and Penicillium were also the prevalent fungal genera in commercial pig feeds, while other fungi belonged to Phoma, Rhizopus and Paecilomyces genera (Almeida et al, 2009). Moderate positive correlations were found between the total fungal count and moisture content, in the feed samples for piglets (r = 0.50) and fattening pigs (r = 0.40).…”

“…Furthermore, in the mycological analysis of pig feed samples from northwest of Croatia, Pleadin et al (2012) have determined the total number of fungi ranged from 1 × 10 3 to 1 × 10 5 cfu g -1 . Then, Almeida et al (2009) have established the mean number of fungi of 6.6 × 10 2 cfu g -1 (range from 2.7 × 10 1 cfu g -1 to 2.7 × 10 3 cfu g -1 ) in pig feed samples from Portugal. In Argentina, Pereyra et al (2011) analysed mycobiota contamination in 90 samples of raw materials (milled maize, whole soybean, wheat bran and soybean pellets) and finished feed for fattening pigs (suckling pig, piglet, weaner, growing and boar).…”

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.
