dc.description.abstract | The presence of harmful pathogens and toxins in animal
feeds is an important aspect of feed quality and has
implications to animal and human health as well as the environment. To assess the distribution and levels of these
microbiological feed contaminants in dairy cattle feeds, 100
dairy farmers were randomly selected in Nairobi area
and the range of feed concentrates frequently used on the farms sampled. Using novel ELISA kits, the feed
ingredients were analysed for aflatoxins,
Salmonella
spp
.,
E. coli
and total microbial counts. Preliminary results
indicate that over 50% of dairy concentrates sampled were contaminated with aflatoxins,
Salmonella spp
. and
E.
coli
. The
most susceptible concentrates included cotton seed meal, maize germ, commercial dairy meal and home
made rations. Although the exact source of contamination was not ascertained, storage conditions in majority of the
farms were characterised by lack of adequate ventilation and dampness. It is known that frequency and levels of
contamination are related to weather conditions as well as to agronomic, storage and handling practices. The study
suggests that there is need to identify sources of contaminants for dairy concentrates and their residues in dairy
products. | en |
