Episode Summary:
In 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 Newton 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 Notes:
Topic: SubQ vs. IM – Choosing the Right Cannula Length in Remote Delivery
Host: Josh – White-tailed deer farmer & remote delivery expert
Key Takeaways:
- 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.

Episode Highlights:
“It’s not one-size-fits-all — needle length should match the animal, the season, and the job.”
“Half-inch is king for SubQ; one-inch is your go-to for reliable IM in larger animals.”
“Look for that little neck pocket — it’s the sweet spot for SubQ.”
