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

In a series of four papers computerized herd reports for dairy herd health and production control purposes, the Index Lists, are presented. This third paper deals with Index List 3 on youngstock rearing and cow culling. The information from this list is suitable for monitoring rearing efficiency and culling policy in a veterinary herd health and production control programme, especially when used in combination with information from the other index lists. Methods for interpretation and evaluation of the data are provided. It is demonstrated how prompt computerized analysis of current information is used to detect deviations in index figures and to advise the farmer.
