Dairy cattle farming is a major economic activity in Kenya contributing 3.5 percent of the national GDP; and providing income, employment and food to 1.6 million smallholder dairy farmers. The country¿s milk production is low, at 5.8 billion litres against the annual potential of 16.6 billion litres. The major constraint in the dairy industry in Njoro Sub-County is inadequate utilization of management by smallholder dairy farmers leading to low milk yield. Over 80 per cent of the smallholder dairy farmers and all livestock extension staff in Njoro Sub-County own mobile phones which can be used by extension staff to pass on management skills to dairy farmers.
