“…Table 1 showed the frequency of isolated fungi genera in both private and commercial poultry feed samples, where a significant difference was obtained (X 2 = 199.818; P < 0.05 and X 2 = 237.053; P < 0.05) respectively, being the genus Aspergillus and Penicillium the most frequently isolated. This result is similar to the ones obtained by Rosa et al (2006), Oliveira et al (2006) and Figueroa et al (2009), who found that Aspergillus and Penicillium were the most frequently isolated genera in the poultry feed samples analyzed. Aspergillus has been shown to be predominant in cereals and other ingredients used in producing poultry feeds in the tropics as in the case of Nigeria (Pitt & Hocking, 1997;Makun et al, 2009).…”

In Nigeria, concentrated poultry feed is a vital component of animal production and health but there was no reliable mycogram in Niger state, Nigeria. As a result this study determined the incidence of mycotoxigenic fungi in both commercial and privately milled concentrated poultry feeds. A total of 100 poultry feed samples consisting of 52 privately milled poultry feed and 48 commercial feed samples were collected. Mycoflora in the feed was determined. Nine fungi genera were isolated. The most frequently isolated fungi genera in both privately milled and commercial feed was Aspergillus spp which was about 40% of mould isolate. Penicillium spp is 20% in private feed and 13% in commercial feed. A total of 874 fungi were isolated consisting of 458 fungi species in privately milled feed and 416 fungi species found in commercial feed. Mycotoxigenic fungi genera, Aspergillus, Penicillium, Fusarium and Alternaria were isolated. Aspergillus flavus is the commonest isolated fungi species.

“…This result is in agreement with the researches conducted by Dalcero et al (1997), Oliveira et al (2006), Rosa et al (2006), Krnjaja et al (2007) and Saleemi et al (2010), where they reported high levels of fungal contamination in feed. In this study, isolation frequency of different genera of contaminating fungi ranked in decreasing order; asperillus, rhizopus, mucor, yeast, dermatophyte, fusarium and penicillium which was in concordance with Saleemi et al (2010), Sivakumar et al (2014) and Bhuyan et al (2015).…”

Contamination of poultry feeds with mycotoxin-producing fungi such as Aspergillus spp is a major threat to animal and human food. This study was conducted to determine the occurrence of aflatoxigenic strain of fungi in feeds, fed to birds in live-bird markets. Feed samples were collected from feeding troughs and feeder in cages of birds and were inoculated on Sabouraud dextrose agar and Czypeck dox agar. Of 300 feed samples, 283 yielded various fungal growth belonging to seven genera, four of them known to be mycotoxigenic. Aspergillus, Rhizopus, Mucor, Dermatophyte, Yeast, Fusarium and Penicillium, whose isolation frequencies were 78%, 6%, 5.67%, 2%, 2%, 0.33% and 0.33% respectively. The aflatoxin producing Aspergillus spp isolated were A. flavus, A. parasiticus and A. nomius 126 (42%), 27 (9%) and 3(1%) respectively. In conclusion A. flavus was the most frequently isolated, and it is a known aflatoxin producer. It is recommended that mycotoxin binders should be added to poultry feed to mitigate the effect of aflatoxin contamination of feed in live-bird market.

“…In this study F. verticillioides was found as predominant followed by F. subglutinans. This prevalence has been informed from poultry feed in Latin America Magnoli et al 1998;Oliveira et al 2007). However, Argentinean samples always showed higher F. verticillioides isolation frequency than Brazilian samples.…”

The aim of the present study was to determine the mycobiota and natural levels of mycotoxins such as zearalenone, fumonisin B(1), aflatoxin B(1) and ochratoxin A present in raw materials and finished fattening pig feed. Samples were examined for total fungi and genera distribution. Zearalenone, FB(1), AFB(1) and OTA contamination were determined using high pressure liquid chromatography and thin layer chromatography. Milled maize and finished feed samples showed fungal contamination over than 1 × 10(4) CFU/g. All samples contained at least one of the main mycotoxigenic genera Aspergillus, Fusarium and Penicillium. A. flavus and F. verticillioides were the most prevalent species. Only some Aspergillus section Nigri strains from suckling pig to growing pig samples were able to produce OTA. A. flavus strains from milled maize, wheat bran, suckling pig to growing pig samples were able to produce AFB(1). All samples were positive for FB(1). Sucking pig, piglet, growing and boar feed samples showed ZEA natural contamination. AFB(1) and OTA contamination were not detected. There was a 100% correlation between FB(1) and ZEA contamination in sucking pig, piglet, growing and boar feed samples; 50% piglet samples and 67% suckling pig samples showed ZEA levels over the recommended limits. The present study has shown the occurrence of two mycotoxins, FB(1) and ZEA in feed intended for fattening pig consumption. In animal production, the simultaneous presence of toxicogenic fungi and low dietary levels of mycotoxins in field conditions can cause possible health impacts and lost performance in pigs from feeding spoiled feeds.
