Write a message to the logfile when every n-th animal record is processed; 0 suppresses output of any animal record-specific log messages. If LOGfreq is set to 1 a record will be written to the logfile for each lactation processed. This can consume large amounts of storage if you're processing lots of records.
LOGfreq = 0
