Samples of pig producers and buyers operating at Blayney Abattoir were surveyed for their willingness to pay for the pig carcase classification service which has been in operation there since 1974. The survey of producers encountered few problems. The service was valued at more then twice its cost by seventy-one respondents representing about one third of producers normally supplying Blayney. The survey of buyers was less successful and little reliance was placed on its results.
