Knowing Your Bug to Choose Your Drug
December 6, 2024The dairy industry is undergoing significant changes in milk markets and pay structures across the globe. However, one principle remains constant: milk quality still matters. While some may overlook milk quality due to the absence of premium payments, maintaining high standards is essential for herd health, customer trust, and the industry’s long-term sustainability. Producing high-quality milk isn’t just about chasing premiums—it’s about preserving the integrity of the industry and ensuring its social license to operate in the future.
Why Milk Quality Matters
Milk quality extends far beyond financial gain. While higher quality milk may not always fetch direct premiums in the mailbox, it has a profound impact on cow health, dairy profitability, and consumer trust. Ensuring milk quality can be the difference between a sustainable, thriving operation and one that struggles to remain viable. Regulatory pressures and consumer expectations are also increasing, making milk quality a potential requirement for continued industry participation in the near future.
The Role of Somatic Cell Count (SCC)
Somatic cell count (SCC) serves as a key indicator of milk quality and cow health. SCC measures the level of infection that cows are battling at both the individual and herd levels. High SCCs indicate the presence of infection, even in the absence of clinical signs of mastitis. This is critical because when cows fight infections, the damage to their udder tissue is often irreversible. Scar tissue replaces damaged tissue, permanently affecting milk production, milk quality, and overall cow health. Monitoring and managing SCC is vital to prevent long-term harm to the herd and sustain milk production.

Tracking and Managing SCC
Effective SCC management starts with data collection. Dairy operators should track bulk tank SCC, individual cow SCC, stage of lactation SCC, and bulk tank cultures. Each of these metrics provides insight into herd health and highlights areas for intervention. The most effective approach is to maintain individual cow-level data through test day records. This allows producers to pinpoint issues within specific groups, such as transition cows, fresh cows, or heifers. Identifying patterns in SCC data can reveal problems for example in heifer raising programs, parlor procedures, or potential contagious mastitis outbreaks.
Relying solely on clinical mastitis cases, bulk tank SCC or cull rates to assess milk quality is too late in the process. By that point, damage has already occurred. Early intervention and continuous monitoring at the individual cow level are essential to reduce SCC and prevent long-term production losses.
Preventative Management for Milk Quality
Proactive management of milk quality should be a top priority for all dairy operations. Prevention is always more effective than treatment, and the industry is already signaling the shift toward stricter quality standards. To avoid falling behind, operators should leverage existing tools and resources for continuous quality improvement.
- Routine Testing and Data Collection: Track SCC at the bulk tank and individual cow level. Use this data to identify trends and potential problem areas before they escalate.
- Collaborate with Industry Experts: Consult with herd veterinarians, milk quality specialists, and vendor representatives who have a vested interest in supporting your success.
- Review Parlor Procedures: Parlor management plays a vital role in milk quality. Ensure milking protocols are followed, and train staff to reduce the risk of mastitis transmission.
- Enhance Heifer Management: Young stock programs have a significant impact on milk quality. Pay close attention to heifer nutrition, environment, health, and development to establish a strong foundation for future milk production.
Actionable Strategies for Improving Milk Quality
To ensure consistent milk quality, dairy operators should employ a structured approach that focuses on prevention, intervention, and continuous improvement. Here are key strategies to implement:
- Data-Driven Decision Making: Use SCC data to guide management decisions. If a spike in SCC is detected, identify the affected group (e.g., fresh cows, heifers, or transition cows) and implement corrective actions.
- Employee Training: Ensure milkers understand the impact of SCC and their role in maintaining milk quality. Consistent training on proper milking procedures, parlor hygiene, and mastitis prevention is essential.
- Routine Equipment Maintenance: Regularly check and maintain milking equipment to avoid issues that could compromise milk quality, such as faulty pulsators or liner slippage.
- Biosecurity and Contagion Control: Limit the spread of contagious mastitis pathogens through segregation and culling strategies. Identify cows with persistent high SCC and take action to prevent infection spread.
The industry’s expectations for milk quality are evolving, and future regulations may mandate it as a requirement for continued dairy production. Dairy operators must stay ahead of the curve by tracking SCC, improving herd health, and employing proactive management practices. The resources for addressing milk quality issues are readily available through herd veterinarians, milk quality advisors, and software tracking tools. By prioritizing milk quality, producers protect not only their herd’s health but also the future of their operations.
Don’t wait for the industry to demand it—the message is clear: milk quality is non-negotiable. Invest in it now to ensure a sustainable, profitable, and respected dairy business for years to come.
