Episode SummaryIn this episode of Pneu-Adventures, host Josh dives into the critical differences between subcutaneous (SubQ) and intramuscular (IM) injections in the remote delivery system space. Drawing from years of experience with white-tailed deer, Josh explains how to choose the right cannula (needle) length for various species, weights, and seasonal conditions. He shares real-world examples from deer farming and livestock management, emphasizing that needle size is not a one-size-fits-all decision. Whether you’re administering antibiotics to cattle or sedation to deer, this episode breaks down when to use ½-inch, ¾-inch, or 1-inch gel collar cannulas to ensure the most effective and humane delivery.Show NotesTopic: SubQ vs. IM – Choosing the Right Cannula Length in Remote DeliveryHost: Josh – White-tailed deer farmer & remote delivery expertKey Points Covered:Defining SubQ vs. IM:- SubQ (subcutaneous): Injection beneath the skin into the fatty layer.- IM (intramuscular): Injection deep into the muscle.Species & Weight Considerations:- Smaller animals (e.g., young deer, fawns): Shorter cannulas like ½-inch or ¾-inch.- Larger animals (e.g., 250–300 lb bucks, cattle): Longer cannulas, often 1-inch, for IM work.Seasonal Adjustments:- Winter coats & added fat may require longer cannulas for effective IM delivery.- Summer: Thinner hides and reduced fat make shorter cannulas sufficient.Application Examples:- Deer sedation: 1-inch for deep muscle injection in larger bucks.- Cattle antibiotics: ½-inch for consistent SubQ delivery in the neck region.Best Practices:- Match RDD volume and cannula length to species, size, and intended injection type.- Consider anatomy and seasonal changes before selecting equipment.Pro Tip:- The “ozone” spot (neck forward of the front shoulder) is ideal for SubQ in most livestock.
