    In most developing countries, livestock production is an important part of national economy. A major constraint for increased milk production by small and medium dairy farmers is the chronic shortage of affordable feeds of adequate quality and quantity, particularly during the dry season. The problem of feed storage is further complicated by farmer’s inability to use them before they spoil, especially during wet season when there is a production peak. During peak production, one of the major agents of feed spoilage, are moulds. Though their prevalence and rate of colonization are highly dependent on climate and farm practices, the growth of moulds in raw material and finished feeds of livestock is an universal problem. Mould spores, of the so called field fungi, can contaminate cereal grains and stover in standing crop in severe conditions (too wet or too dry season). These include species of Fusarium, Altemaria, Cladosporium, Diplodia, Gibberella and Helminthosporium, their spores can germinate, especially under high moisture conditions (20-21%). The moulds can also c olonize on feed ingredients and feeds during storage especially with Aspergillus and Penicillium species at 13-18% moisture. Both field and storage fungi can result in elaboration of mycotoxins.
