Adoption of technology, management practices, and production systems in US milk production

The introduction of new technology, management practices, and alternative production systems has resulted in rapid structural change in the US dairy industry. This paper examines adoption rates and adopter characteristics for the following dairy technologies, practices, and systems: holding pen with an udder washer, milking units with automatic take-offs, genetic selection technologies, recombinant bovine somatotropin, membership in the Dairy Herd Improvement Association, computerized feed delivery systems, computerized milking systems, use of a nutritionist to design feed rations, grazing, milking cows 3 times daily, and milking parlors. Four of these were used on a greater percentage of farms in 2005 than in 2000, but increased farm sizes and the interaction of farm size with adoption suggest a greater percentage of milk being produced under each, with the exception of grazing. Except for grazing, technologies were generally complementary.
