4 Proactive farm management via
the Herd Navigator 100 system
Traditionally, farm management is based on
here-and-now actions from observations made in
the herd, together with information from the farm
management system and other data sources.
By analysing progesterone, Herd Navigator 100
creates alarms for heats, pregnancies, abortions
and reproduction disorders.
The Herd Navigator 100 biomodel tells the sys-
tem when different cows need to be sampled.

4.1 Biomodel

The Herd Navigator 100 biomodel:
n Tells the system when different cows need to
be sampled.
n Processes the results from the milk sample
analysis.
Updates the state of each cow, whenever a
n
new measurement result is received.
n Self-learns, which means that estimations
and predictions of the state of individual cows
improve each time the cow is measured.
n Sets heat alarms, along with an estimate of
the quality of the heat.
n Adjusts the reproduction status from anoes-
trus, to cyclic and then to potentially pregnant
depending on progesterone measurements.
n After insemination, confirms pregnancy and
checks for possible abortions.
n Issues warnings of abortions.
n Issues risks for prolonged anoestrus, follicu-
lar cysts, and luteal cysts.
Note! To get proper results, it is very important
to continuously update the cow calendar in Del-
Pro Farm Manager software. Reproduction
events, latest calvings, inseminations and preg-
nancy checks need to be registered in the system
daily.

4.2 Distribution of cows in the herd

The system is developed for all year calving and
not for strict seasonal calving.
