The present study examined the effect of the mastitis control program (MCP) on milk production, incidence of mastitis, incidence of teat lesions, culling, log10 of the bulk tank milk somatic cell count (LBMSC) and economic returns in Valdres, Norway, during 1982-1985. The major economic impact of the MCP was due to improved milk quality and to a lesser degree due to increased milk production. This might be explained by the Norwegian policy aimed at reducing the milk surplus through production quotas. The net present value of MCP, using a 15% discount rate, for an average 12-cow herd was 5599-3372 Nkr ($800-482) for production within or above the milk production quota, respectively. Since the program was provided free of charge to the individual farmer, this was also the net benefit to the MCP-participating farmer.
