The document discusses plans for a project that aims to identify a diverse group of smallholder dairy farmers in Tanzania to participate in collecting data on breed composition, productivity, and fitness in order to develop mechanisms for encouraging continued participation and adoption of improved management practices. Criteria for selecting farmers include random selection across study sites, owning a cow that recently had a calf or is pregnant, and a willingness to participate. Data to be collected includes reproductive performance, health, production, animal health, welfare, inputs, and enterprise characteristics.
