Your horse tested positive for the Px variant -- now what?
This 6-page starter diet template was created by Stephanie Carter, FNTP, IHP, author of Managing Muscle Mayhem and Equine Functional Nutrition, to help you take the first step toward supporting your Px horse through species-appropriate, functional nutrition.
The Px variant affects the calcium channels responsible for telling muscles when to contract and when to relax. The result is muscles that cannot fully turn off, creating chronic tension, hypersensitivity, and reactive behavior that is often mistaken for a training problem. Px also amplifies other MIM variants, making multi-variant horses significantly harder to manage without dietary intervention. This template addresses those root causes through targeted nutritional support designed specifically for the Px variant.
What's included:
- Plain-language explanation of what the Px variant does and how calcium channel dysfunction affects behavior and performance
- Key dietary principles specific to Px
- Twice-daily feeding chart with serving ranges based on an 1,100 lb horse (scalable by body weight)
- Region-specific product recommendations for the US, Canada, UK/Ireland, EU, and Australia/NZ
- 4-week transition schedule for safe diet changeover
- Label-reading quick reference to identify ingredients to avoid, including Px-specific restrictions
- Important transition notes including detox expectations
This template is designed for single-variant Px horses. If your horse carries multiple variants, has metabolic challenges, or is not responding after 8-12 weeks, a personalized nutrition consultation is recommended at stephaniecarterntp.com.
