Comparing a cow’s SCC at the previous test day to the current test day SCC in her current lactation in a scatter-plot graph shows the prevalence of cows in these 4 categories:
- Not infected – previous and current SCC < 4.0
- New infection – previous SCC < 4.0 and current SCC >=4.0
- Cure – previous SCC >=4.0 and current SCC < 4.0
- Chronic – previous and current SCC >=4.0
In addition to summarized SCC herd data, the Udder Health Monitor report includes lists of infected cows that may need specialized attention. Milk samples may need to be collected and cultured, cows may benefit from treatment or other action may be required.
The Udder Health Monitor report (DHI-427) is available on a monthly or quarterly basis. More information about these reports can be obtained from the herd’s DHI information specialist or technician.
Managing udder health in dairy herds requires routine monitoring of individual cow and herd SCC information. The Udder Health Monitor can be a valuable tool for herd owners and managers as well as herd veterinarians to identify potential problems in the herd mastitis control program and opportunities for improvement.
