Atypical Interstitial Pneumonia in Cattle Grazing Perilla Mint

A severe type of pneumonia, often resulting in death, can result from the ingestion of the leaves and seeds of perilla mint. The time of year when perilla mint reaches the seed stage often corresponds to periods when pasture is scarce, enticing cattle to consume plants they normally avoid. The flowering or seed parts of perilla mint contain the highest concentration of perilla ketone, considered the most toxic agent involved.

Summer Reminders

With the hot summer weather now in full swing, remember to review your grazing program to reduce heat stress and provide adequate forage for your cattle.

Providing Water for Beef Cattle in Rotational Grazing Systems With Tire Waterers

Location of a watering source in a grazing system is critical. Watering sources can influence grazing, compaction, and manure/nutrient deposition patterns. Tire waterers located in a central location can be used to provide water to many paddocks in a grazing system.

Tips for Stockpiling Fescue

Stockpiled fescue is an option to provide quality grazing during the early winter period when forages are not actively growing. To take advantage of this practice, a field needs to be selected in August and not grazed again until November or December.
