As with any grain or meal feed products need to be kept dry as moisture combined with heat can cause fungi to grow. Common on farm storage methods are: in a shed or unused fertiliser bin; in a covered pit; on a concrete pad; or in a cutting, covered with plastic sheet and tyres. Most feed should be used reasonably expediently (within 40 - 50 days). The longer you plan to store feed products the better your storage facilities need to be.
