In a series of four papers computerized herd reports on various aspects of dairy farming, the Index Lists, are presented for herd health and production control purposes. This second paper presents Index List 2, on calving, breeding efficiency and lameness. The information from this list is suitable to monitor herd performance, especially when used in combination with information from other index lists. Methods for interpretation and evaluation of the data listed are provided. Evaluations should take those aspects related to reproduction and lameness into account. The use of current information and prompt computerized analysis in detecting deviations in index figures and providing advice to farm management is discussed.
