Plant and Cleaning thresholds can be adjusted in Herd-man. Go to Summary Reports -> Plant/Cleaning Report -> Sensitivity Settings.
Mastitis
|
| Mastitis Ratio |
The ratio of a single cows mastitis measurement compared to the rest of the herds measurements. It is measured over a 5 day period. A ratio of 1 indicates a cow that is unlikely to be infected. The higher the ratio the higher the possibility of infection.

| Prime Mastitis Ratio |
A ratio that compares a single cows mastitis measurement against her own measurement from 7 days ago. A ratio of 1 indicates no change in measurements and she is unlikely to be infected. The higher the ratio, the higher the possibility of infection. The acceptable range of measurements is 0.95 - 1.05.

Yield
|
| Yield Ratio |
A ratio enabling you to track a single cows performance against the herd average. The average producers are given a ratio of 1. A cow with a ratio of 0.5 is thus producing 50% of the average cow in the herd.

| Litres |
The volume in litres the average cow is producing after you have entered your vat pickup information.

| Milk Efficiency |
To be used in conjunction with live weights (Walk over Weighing needed). The cow's production adjusted for her weight over 7 days, and averaged at 100. Cows below 100 are producing less volume per weight than the average cow in the herd.

| Yield 2wks |
A change in the yield ratio measured against the cow's yield ratio 2 weeks ago.

Cleaning Performance
|
| Volume Ratio |
Sufficient quantity of water over the cleaning cycle to sweep out milk residues in pipework. Ratio begins at 0 with a recommended setting of 2.0. Volume Ratio errors occur when the ratio is outside of 1.7 - 2.5 and may be due to insufficient hot water in hot water cylinder, blocked jetters or broken rubberware. |
| Flow Ratio |
Speed of water needed to clean corners and pipework efficiently. Ratio begins at 0 with a recommended setting of 0.8. Flow Ratio errors occur when the ratio is outside of 0.72 - 1.00 and may be due to blocked jetters, incorrectly balanced jetters or folded rubberware. |
| Hot Water Temperature |
Average Hot Water wash temperature of all the bails. Measured in degrees Celcius with a recommended setting 65°C. Hot Water errors occur when the temperature is colder than 61°C and hotter than 81°C and are due to the hot water wash not being up to temperature, or being too hot. |
Plant Performance
|
|
Slip Ratio
|
Small bubbles of air seen in the milk through the bail. Slip ratio begins at 1 with a recommended setting of 2. Slip Ratio errors occur when the ratio is outside of 1.8 - 2.5 and may be due to broken or split liners. |
| Air Ratio |
Gulps of air seen in milk through the bail. Air ratio begins at 1 with a recommended setting of 1.3. Air Ratio errors occur when the ratio is outside of 1.2 and 2.0 and may be due to a claw bowl hole, loose claw bowl or split rubber. |
| Duration (Slow) Ratio |
Time a given bail takes to milk out a cow vs other bails. Duration (Slow) Ratio begins at 1 with a recommended setting of 1.2. Duration (Slow) Ratio errors occur when the ratio is outside of 1.1 - 2.0 and may be due to a faulty pulsator, incorrect air flow or low vacuum. |
