Anyone planning a major change in the farm business should first budget that change. This involves determining the actual physical changes that would take place and getting down on paper the additional investment required, the increase or decrease in expenses and receipts expected and the change in net income that should result. This booklet is designed to be used in planning and budgeting the change from a conventional stanchion-barn, bucket-milker, hay and silage dairy chore system to the free-stall-barn, herringbone-parlor, high-silage-feeding system. It can also be used when changing to or from other types of systems if the labor requirement factors given are not used. Throughout this paper an example farm is used to show the type of calculations to make. This example farm is modeled after the 1964 average of 434 New York dairy farmers cooperating with the extension service in the dairy farm business management projects. A comparison of the example farm and the average of those farms is shown below.
