In the mid-1990s a project was undertaken to increase cheese production at
the Kaikoura Dairy Go-operative by changing the genetics of the herd to the
beta -lactoglobulin BB phenotype, which produces milk with higher casein l
evels. This paper describes the evidence for the change and presents a case
history of what happened, in the context of a change process in the dairy
industry. Today, the process is incomplete and the company has merged with
a much larger one, thus removing the raison d'etre for the project.
