The most important constraint in dairy cattle production in Kenya is the quantity and quality of feed offered to the animals. This problem can addressed if farm by-products such as maize stover, millet and sorghum stovers are treated for utilization by cattle and other domestic ruminants. The idea is to improve the nutritive value of maize stover and straws by use of urea solution which is usually abundant in the farm.
Zero grazing or stall feeding is basically confining dairy cattle in a stall and feeding them there. There is minimum movement of cattle because they are not allowed to graze in the fields and thus the term zero grazing.
