Index Lists provided by the VAMPP computer programme for dairy herd health and production control. I. Interpretation...

In a series of 4 papers the Index Lists as provided by the VAMPP computer programme are presented. The information on Index List 1, covering milk production, milk quality and udder health, is suitable to monitor actual herd performance, especially when used in connection with the other index lists. With computer programmes becoming available to veterinary control programmes, proper interpretation and prompt analysis of data is more critical. This paper outlines how deviations of index figures from reference values are detected, how analysis may be performed and how advice is built-up.
