Abstract |
Poultry feed has been
reported to be of potential risk to the animals consuming it and also to
man. In the recent time, there is an increase production of food animals
and this consequently informed the rise in the production of feeds. The
quality of feeds produced by local small scale feed mills in Ekiti
State, Nigeria was
investigated using standard microbiological and chemical methods. The total bacterial counts of the ten locally produced poultry feed
samples ranged between 7.58 X 105 and 6.36 x 106
CFU/g. Bacterial count on Bile aesculin agar was lower than counts on
both MacConkey and Salmonella-Shigella agars. The quantitative
enumeration of fungal load showed that Growers mash (FDM) had the
highest amount of fungal propagules followed by Grower mash (AMF). Five
genera of fungi were isolated from the feeds comprising
Aspergillus (3),
Abscidia (1), Fusarium
(1), Penicillium
(3) and Rhizopus (1). At least one mycotoxigenic strain
was isolated from all the feeds. In this study the values of the
bacteria and mould in the feeds were below the maximum allowable loads.
Out of the nine fungal species isolated
Aspergillus flavus had the
highest relative density of 70% and isolation frequency of 20.59%. The
occurrence of aflatoxin B1 was highest in all the feed screened while
aflatoxin G2 was not detected in any of the ten feeds screened. The
level of all the heavy metals in the samples was within the tolerable
levels for poultry. The microbiological and heavy metal qualities of
poultry feeds from small scale poultry
mills was within the
international standard while aflatoxin levels in some of the feeds were
above the maximum allowable levels.
