      abstract = {Year end financial analyses from 158 Michigan dairy farms  for 2001 were studied to see if useful information about  numbers of animals could be derived.  It was found that 121  farms had records adequate to calculate turn over and cull  rates.  The average turn over rate for cows averaged 37 %.   The median turn over rate was 35 %.  The turn over rate  exceeded 42 % on 30 % of the farms.  A scatter diagram  indicated lower turn over rates might be weakly associated  with net farm income per cow.  About 8 % of the farms had  problems in reporting bull calf sales or other disposition.   Nearly 11 % of the farms appeared to not be actually  making animal counts at year end.},
