I - INTRODUCTION
As a matter of fact, the nutrition is considered as one of the major
fHctors in animal production It is well known that feeding of animals IS
depending mainly on fooder crops, agriculture by products and grains or
concentrates Handling, transportation and storage of grain can play a vast
rnle 111 grain contaminatiOn but storage is of primary importance
The basic principles 0f grain storage arc relatively simple. FirstlY,
the product to be stored should be conditioned to a stable state in which
respiration of the seeds and of associated micro- organism are reduced to
mimmum_ fhis is achieved by keeping the moisture content of the gram
and the ambient humidity very low
Secondly, the product should be placed in a container structure
that will maintain a suitable environment and prevent or restrict the
entrance of insect and animal pests
Lastly, the grain should be accessible throughout the storage
pcnod for additional treatment if necessary to maintain good condition,
panicularly with respect to heating and moisture absorption Protection
lfom molds has been become very important due to increased awareness
or the hazards of mycotoxins to the human and animal health .Thus,
temperature and moisture content control are important considerations for
prevent ton of molding (FAO, 1979) One common storage problem ts
moldiness and aflatoxicosis which is poisoning caused by one or more
atlatoxins (Valentine, 1990)_ Aflatoxin contamination of agricultural
commodities, including corn, cottonseed, peanuts, barley and many other
oll - rich crops such as tree nuts, can occur following A.~perxil!us ”fJp.
(’-’lana, (’/a!.. J99:i ).
The aim of this work is to study the eflect of some storage
c<.l!lditions mainly, temperature and moisture content on the nutritive
value of some grains ( corn and barley ) incorporated in small ruminant
rations and to determine total aflatoxins in corn and barley under some
storage conditions Their effect on daily gain and some other parameters
are also stuclted
