The Johnson County livestock community gathered on May 12, 2025, for a crucial discussion led by Keeley Clark, president of KC Livestock Consulting. The meeting focused on three significant threats to livestock production: grass tetany, environmental contaminants, and rabies.

Clark began by addressing grass tetany, a metabolic disorder affecting cattle, particularly pregnant cows and those under stress. This condition arises from low blood magnesium levels, often triggered by grazing on lush pastures. Early signs include twitching and a stiff gait, but if untreated, it can lead to severe symptoms and even death. Clark emphasized the importance of magnesium supplementation and monitoring pasture grasses to prevent this disorder.

The conversation then shifted to environmental contaminants, specifically PFAS (per- and polyfluoroalkyl substances). Clark highlighted a concerning trend where fertilizers, particularly those derived from biosolids, have introduced these harmful chemicals into the environment. Reports indicate that PFAS contamination has led to health issues in livestock and chronic conditions in farmers. Clark urged ranchers to reconsider their fertilizer choices to avoid long-term damage to their land and livestock.

Lastly, Clark discussed the risks associated with rabies in livestock. Although rare, rabies can be fatal and is often misdiagnosed in animals. The meeting underscored the importance of vaccination, especially for animals that interact with humans, to prevent outbreaks and protect both livestock and handlers.

In conclusion, Clark's presentation aimed to equip ranchers with knowledge to safeguard their herds against these invisible threats. By addressing these issues proactively, the livestock community can enhance animal health and ensure sustainable farming practices in Johnson County.
