Detection of health disorders
Acute cases
Acute health disorders change the milk fast. HerdLine raises a warning when the numbers move together, so the farmer can act the same day.
How the warning works
An Acute warning is an initial diagnostic aid. It appears when deviations occur in at least two of three measurement groups:
Compositionfat, protein, lactose and the F/P ratio
Daily yieldmilk per cow per day
Temperaturemilk temperature at milking
Early warnings let farmers respond quickly and limit losses.
Common causes
- Sudden diet changes that disrupt rumen fermentation and can cause acute milk fat depression.
- Stressful events — transport, abrupt environmental changes, pathogen exposure.
- Toxic plants or contaminated feed.
- Metabolic disorders such as ruminal acidosis or ketosis.
- Infectious diseases including mastitis, pneumonia, foot rot and metritis.
- Heat stress in hot, humid conditions, causing dehydration and reduced feed intake.
- Trauma — wounds, fractures, internal injuries.
- Poor housing, overcrowding, inadequate ventilation and harsh weather.
On the farm
- 6 April
The in-line analyser detects a significant rise in the F/P ratio and a drop in milk yield. HerdLine raises an Acute warning.
- Shortly after
Ketosis is diagnosed and treated immediately.
- Following days
The cow's health indicators and milk yield return to the healthy range.
