Differential Somatic Cell Count: Value for Udder Health Management

Area of Science:

• Veterinary Medicine
• Animal Science
• Dairy Herd Health

Background:

• Intramammary infection (IMI) causes mastitis, a significant economic and health issue in dairy cattle.
• Somatic cell count (SCC) is a standard indicator for IMI, reflecting immune cell presence in milk.
• Differential somatic cell count (DSCC) has potential for IMI detection but lacked automated measurement until recently.

Purpose of the Study:

• To review insights on DSCC measured by two new automated machines.
• To evaluate the potential value of DSCC in udder health management for dairy cattle.
• To identify future research directions for DSCC in improving udder health.

Main Methods:

• Literature review of available data on DSCC measurement.
• Analysis of insights from two newly introduced automated DSCC machines.
• Exploration of the utility of DSCC as an indicator for IMI.

Main Results:

• Two new machines now offer automated milk DSCC measurement.
• DSCC shows promise as an additional indicator for IMI detection.
• The insights suggest DSCC's potential role in dairy herd udder health management.

Conclusions:

• Automated DSCC measurement is now feasible with new technology.
• DSCC may enhance the ability to manage udder health in dairy cattle.
• Further research is needed to fully establish the value of DSCC for IMI and udder health.
