Abstract:
The objective of this review is to document an effective preservation and utilization strategy of wet brewery
grain as alternative feed for high cost concentrate feeds. In many areas, getting feed with less costs and maximizing
profitability becomes a great concern for dairy farmers. Wet brewery grain is one of the cheapest protein rich agroindustrial
by-product in Ethiopia. The short lifespan of the wet brewery grain associated with its high moisture content
is the critical problem of farmers in utilizing the by-product. On the other hand, cost of drying is one challenge which
leads farmers to directly use wet brewery grain. It is found that ensiling of wet brewery grain alone and with other
feed is ecologically acceptable, economically feasible and easily applicable technology to dairy farmers in developing
country. Therefore, reviewing different preservation mechanisms and documenting of different strategy is very crucial
for storing and utilizing this abundant feed without spoilage. The review is aimed at documenting the existing strategies
for preservation of wet brewery grain to apply strategies in the country context for tackling feed shortage, preventing
environmental pollution and improve productivity of dairy cows in the country.
