Adoption of rBST on Wisconsin dairy farms has been modest, and is limited by farm operations: (1) finding rBST disadvantageous given their moderate scale and lack of use of technologies and practices that improve its efficacy; (2) using alternative production systems that make rBST use less likely; and (3) working with handlers that market dairy products to consumers from cows not treated with rBST.

Key words: Adoption; dairy farm technologies; recombinant bovine somatotropin; rBST; size-bias.
