Discover how teat sealant excretion post-calving impacts udder health and ease of milking. Are you optimizing your dairy cow treatment for better results?

For dairy producers, maintaining ideal udder health is vital. A healthy udder leads to higher milk outputs, excellent cow health, lower vet expenses, and constant milk quality. Still, elements like mastitis may compromise udder condition.  As we strive to reduce antibiotic usage in cattle, herd management techniques are evolving. Selective dry cow treatment programs are gaining prominence, a superior alternative to blanket dry cow treatments with antibiotics. Based on the cow’s somatic cell count (SCC), these programs utilize internal teat sealants (TS) either with antibiotics or alone. This approach, in line with antibiotic stewardship guidelines, reduces antibiotic consumption and helps maintain udder health, leading to improved milk quality.

Revolutionizing Dry Period Management: The Role of Selective Dry Cow Treatment (SDCT) in Modern Dairy Farming 

Maintaining udder health throughout the dry period—when a dairy cow is not lactating—is vital in the dairy business. This time frame helps prevent diseases that can compromise the health of the herd or a cow’s output. Mastitis was historically prevented by antibiotics during drying out (DO). However, more rigid EU rules and issues with antibiotic resistance have resulted in selected dry cow treatment methods (SDCT).

SDCT uses internal teat sealants (TS) alone or with antibiotics based on individual cow infection risks: 

1. High Somatic Cell Count (H-SCC) Cows: Cows with high somatic cell counts (SCC) are prone to infections and are treated with both antibiotics and TS (H-ABTS). Antibiotics treat existing infections, while TS prevents new ones. 

2. Low Somatic Cell Count (L-SCC) Cows: Cows with low SCC, at lower infection risk, receive TS only (L-TS), providing a barrier against pathogens without using antibiotics. 

This method guarantees that high-risk cows receive the required therapy and helps reduce antibiotic consumption. However, its success relies heavily on the vigilance of dairy producers and veterinarians in monitoring SCC levels and udder health. By emphasizing their integral role in optimizing SDCT procedures, dairy producers can feel more involved and committed to maintaining udder health.

Unveiling the Secrets of Teat Sealant Excretion: A Comparative Study of High and Low SCC Dairy Cows Post-Calving

Aiming to expose how internal teat sealants (TS) are expelled after calving and their effect on udder health and milking equipment cleanliness, the research Postpartum excretion of internal teat sealant following selected dry cow treatment of dairy cows intended compared TS excretion in low SCC cows treated alone with TS to TS in high somatic cell count (SCC) cows treated with antibiotics. It also measured how well lab staff members and farmers could find TS residues after milking and calving.

The approach was meticulously crafted for consistent understanding. The research included four German herds and 192 cows from Dutch herds three-wise. While low SCC cows (L-TS, n=99) were treated with TS alone, high SCC cows (H-ABTS, n=93) were given antibiotics and TS.

They collected 50 mL pre-milk samples from every udder quarter during the first 15–16 milkings after calving. This technique permitted a thorough study of T’s visibility, amount, and excretion patterns during the first milkings.

Decoding the Visibility of Teat Sealant Residues in Pre-Milk: Insights from Farmers and Laboratories

One of the most critical research results is pre-milk teat sealant (TS) residue visibility. Lab staff members and farmers reported TS residue in 72% of quarters during the first milking post-calving. This notable incidence of detection emphasizes the ubiquitous existence of TS residues in the early postpartum period. It also underscores the necessity of careful surveillance and control, making dairy producers feel responsible and proactive in maintaining udder health and milk quality.

The research initially revealed the farmers’ remarkable sensitivity in spotting teat sealant (TS) residues. In 74.5% of the instances, producers found TS remains during the first milking. However, this capacity experienced an apparent fall during the next three milkings, falling to only 8.3% by the final three milkings. This notable decline emphasizes the difficulties and possible discrepancies in identifying TS residues without expert knowledge or a laboratory environment.

The next milkings clearly showed a change in discharge patterns. Compared to cows in the L-TS group (4.6%), cows in the H-ABTS category showed a greater mean adjusted TS percentage excretion (8.5%) during the second milking. H-ABTS cows showed 1.8% TS excretion. In contrast, L-TS cows showed much lower excretion levels at a 0.4% trend until the third milking. This result implies a clear difference in the pace and persistence of TS excretion between the two groups, suggesting that treatment type and somatic cell count category play significant roles in the post-calving excretion dynamics.

The multivariable model outputs identified essential variables affecting the occurrence of teat sealant (TS) residues in the first three milkings. Especially during the first and second milkings, parity became a significant factor, indicating that multiparous cows were more prone to show TS residues. Furthermore, the research group was strongly linked to T’s presence at the second and third milkings, suggesting that the type of cows—whether treated with antibiotics + TS or TS alone—also greatly affected the appearance and excretion patterns of TS post-calving.

Fascinatingly, the univariable model looking at udder health found no correlation between udder health outcomes and teat sealant (TS) residue present during the first milking. This implies that the general state of the cow’s udder is not immediately affected by the first appearance of TS, which is a crucial realization for farmers considering the advantages and drawbacks of TS application.

Empowering Dairy Farmers: Strategic Insights for Managing Teat Sealant Use and Maintaining Udder Health 

Understanding the post-calving teat sealant (TS) excretion for dairy producers is critical to refining their selected dry cow treatment (SDCT) strategies. The fact that TS residues are most noticeable during the first milking post-calving is a crucial insight. This knowledge helps farmers plan to prevent contamination of milking equipment and anticipate cleaning difficulties, thereby maintaining udder health and milk quality. The need for customized hygiene measures is underscored by the increased TS excretion observed in cows treated simply with TS (L-TS) compared to those treated with antibiotics plus TS (H-ABTS).

Farmers may teach employees to recognize and handle TS wastes, particularly in first milkings when residue visibility is maximum. The research indicates that the difference in residue detection between farms and labs closes with time, implying the advantage of rigorous early monitoring followed by consistent but less frequent inspections. Farmers that follow these guidelines may safeguard udder health and follow the rules on antibiotic restrictions, improving animal welfare and milk quality.

The lack of a clear correlation between TS residue presence at the first milking and udder health confirms that well-controlled TS use does not jeopardize the dairy herd’s health. Optimizing SDCT procedures depends on proper training and equipping farm staff to control TS wastes; so, balancing efficient udder health management and operational effectiveness also depends on this.

The Bottom Line

With an eye on post-calving milking practices, the research emphasizes essential aspects of teat sealant (TS) excretion in dairy cows. Significant results reveal a clear bimodal excretion pattern wherein TS remains are more evident during the first milking. Although their udder health was not much affected, L-TS cows had a greater TS excretion rate (45.5%) at the first milking than H-ABTS cows (32%).

These revelations stress farmers’ need to carefully clean milking equipment to prevent residue development. Farmers can identify TS residues well during the first milking, yet their capacity declines in later milkings. This implies that better training or procedural modifications are needed to maintain milk cleanliness.

Knowing that T’s presence does not compromise udder health lets farmers boldly follow chosen dry cow treatment guidelines. This approach guarantees udder health and farm output by supporting effective herd management and antibiotic reduction policies.

Key Takeaways:

• Internal teat sealants (TS) are being increasingly used in European dairy farms to comply with antibiotic restriction policies and maintain udder health.
• Post-calving TS residues can attach to milking equipment, making cleaning difficult and deterring some farmers from using TS across all cows.
• A study across herds in the Netherlands and Germany compared TS excretion in high SCC cows treated with antibiotics and TS (H-ABTS) versus low SCC cows treated with TS only (L-TS).
• TS residues were visible in 72% of quarters during the first milking, with farmer sensitivity to spot TS dropping significantly after the first milking.
• The study found a higher percentage of TS excretion in low SCC cows (L-TS) at the first milking compared to high SCC cows (H-ABTS).
• TS excretion quantities exhibited a bimodal pattern, with greater excretion in multiparous cows and no link to udder health issues at the first milking.
• Effective management of TS excretion can empower dairy farmers to optimize udder health and enhance milk quality while adhering to antibiotic restrictions.

Summary: Dairy producers need to maintain optimal udder health for higher milk outputs, good cow health, lower vet expenses, and consistent milk quality. Selective dry cow treatment programs (SDCT) are gaining popularity as an alternative to blanket dry cow treatments with antibiotics. These programs, based on the cow’s somatic cell count (SCC), use internal teat sealants (TS) with or without antibiotics. This approach reduces antibiotic consumption and improves milk quality. The success of SDCT relies on the vigilance of dairy producers and veterinarians in monitoring SCC levels and udder health. A study of high and low SCC dairy cows post-calving revealed how internal teat sealants (TS) are expelled and their effect on udder health and milking equipment cleanliness. Customized hygiene measures are necessary, as cows treated with TS had increased TS excretion compared to those treated with antibiotics plus TS. Farmers can teach employees to recognize and handle TS wastes, especially in first milkings. Following these guidelines can safeguard udder health and improve animal welfare and milk quality.
