Three Ways to Optimize Swine Health

Maximizing swine herd efficiency through animal health has become a crucial topic, especially following the recent discussions at the World Pork Expo. This year, several new research findings and innovative products were unveiled that promise to improve swine health and, consequently, the overall profitability of herds. Here, we explore three essential strategies to optimize swine health: focusing on foot health, upgrading air filtration systems, and keeping feed clean.

### Focus on Foot Health

Foot health is often overlooked in swine management, yet recent research indicates that foot lesions are alarmingly common. A comprehensive study by ZinPro Corporation analyzed 30,000 sows across 300 different farms, revealing that an astonishing 90% of these animals had some form of foot lesion. Among these, about 40% experienced severe lesions and inflammation, as noted by Ton Kramer, a business manager at ZinPro.

From a welfare perspective, the implications of foot health issues are significant. Not only are almost all sows affected, but these lesions can adversely impact reproductive performance and the longevity of the animals. Commonly identified problems include white line lesions and heel overgrowth, which are exacerbated by a variety of factors ranging from barn flooring to nutrition and water quality.

Kramer advises regular assessments of herd foot health every six months, ideally conducted during farrowing. While there are no easy remedies like topical strengtheners, the quality of hoof tissue is determined largely by nutrition. Ensuring that sows receive a balanced diet is vital for maintaining strong hooves.

When considering replacement gilts, specific criteria such as proper alignment and weight distribution should be prioritized. Avoid selecting animals that exhibit difficulty in walking, as this can be indicative of underlying foot health issues.

### Upgrade Air Filters

Another critical component in optimizing swine health involves enhancing barn biosecurity through upgraded air filtration. The economic repercussions of outbreaks such as porcine reproductive and respiratory syndrome (PRRS) can be devastating for hog producers. As the virus continues to evolve, integrating new management strategies becomes essential.

American Air Filters (AAF) has introduced high-efficiency air filters designed to mitigate airborne pathogens. A study from the University of Minnesota highlighted that barns utilizing filtered air saw a remarkable 50-60% decrease in PRRS outbreaks. Cesar Corzo, a swine veterinarian and professor at the university, emphasizes that air filtration is a vital layer in comprehensive biosecurity systems, especially in regions with high hog densities.

Though retrofitting barns may involve an upfront investment—around $500,000 for installations on a 5,000-head farm—the long-term benefits far outweigh the costs. Once installed, these filters typically last between four to six years. Carlos Lora, the global director of animal science at AAF, notes that while the initial costs can be steep, the potential savings from preventing outbreaks make air filtration a necessary investment for sustained swine production.

### Keep Feed Clean

The importance of feed hygiene cannot be stressed enough when it comes to maintaining swine health. Animal feed can unknowingly carry disease pathogens that threaten entire herds. To combat this issue, Furst-McNess has developed an additive known as FeedARMOR, designed to minimize the risk of viral disease transmission.

FeedARMOR is an innovative, formaldehyde-free solution that can effectively manage key diseases such as PRRS and porcine epidemic diarrhea virus. Frederick Sandberg, director of research and development at McNess, states that just two pounds of FeedARMOR per ton of feed is sufficient for effective treatment, making it both a cost-effective and practical option.

At less than $5 per ton, FeedARMOR is an affordable measure compared to alternative solutions, ensuring that swine producers can maintain high standards of health without breaking the bank. For optimal results, Sandberg recommends initially mixing FeedARMOR with 15 to 25% of the feed ration before incorporating other ingredients. This method ensures even distribution and effectiveness.

### Conclusion

In conclusion, optimizing swine health is not only essential for animal welfare but also directly correlates with increased profitability for producers. By focusing on foot health, upgrading air filtration systems, and keeping feed clean, swine producers can significantly enhance their herds’ health and productivity.

These strategies, as highlighted by recent developments in the field, are not mere options but fundamental approaches that every producer should incorporate into their management practices. The potential for improved reproductive performance, reduced disease outbreaks, and overall herd efficiency makes these initiatives not only beneficial but necessary in today’s competitive market. As we continue to explore advancements in animal health, it is clear that prioritizing these strategies will set a solid foundation for future success in the swine industry.
