High Octane Fitter 52
Aggressive, fast-acting fat trimming and muscle definition — used when time is short and a lamb is too fat
Always read and follow product labels for feeding and sheep safety.
Overview
Fitter 52 is Purina’s aggressive fat-trimming supplement — the faster, harder-acting counterpart to Fitter 35. Where Fitter 35 works gradually over extended time, Fitter 52 is formulated to produce maximum results in a short window, making it the tool of choice when a lamb is too fat and the show is approaching. Both are safe for sheep with no added copper. Fitter 52 appears to be a newer addition to the High Octane lineup alongside Fitter 35.

How Experienced Feeders Actually Use It
Fitter 52 is the emergency version of Fitter 35 — pulled out when a feeder realizes a lamb is too fat with limited time to fix it. Because it works faster and more aggressively, it is not typically run for the full duration of a program the way Fitter 35 might be. Feeders use it as a 2-4 week correction tool, then ease off as the lamb sharpens up. The same rule applies: reduce energy feeds simultaneously or results are counteracted.
Real-World Feeding Rate
- Typical rate: 8–16 oz/day for the correction period
- Introduction timeline: Immediate — no ramp needed. Run until lamb reaches target condition, then back off.
Common Deviations from Label
Feeders often use Fitter 52 for a defined short correction period (2-4 weeks) rather than as an ongoing supplement. Pulling it too close to show day without re-introducing bloom support can leave the lamb looking sharp but flat.
Breed-Specific Notes
Same applications as Fitter 35 — more commonly used with naturally fleshy breeds. The more aggressive action of Fitter 52 suits situations where a naturally heavy-fleshing lamb has gotten out of control on cover.
Phase Protocols
Weeks 8–6 | Condition Building Phase
- Rate: 8–16 oz/day
- Purpose: Aggressive cover correction if lamb entered this phase too fat. Reduce Golden Ticket and energy grains simultaneously.
Weeks 5–3 | Fill & Shaping Phase
- Rate: 8 oz/day tapering — ease off as lamb reaches target condition
- Purpose: Fine-tune leanness, transition back toward bloom supplements as cover normalizes
Weeks 2–1 | Final Prep Phase
- Rate: Use with caution at 4–8 oz/day only — easy to over-lean a lamb this close to the show
- Purpose: Last resort sharpening only
Stacking Protocols
Conflict — Fitter 52 + Golden Ticket at full rate: Direct opposition. Reduce or pause Golden Ticket and energy supplements when running Fitter 52 aggressively.
Fitter 52 + Champion Drive: Compatible. Champion Drive runs throughout.
Fitter 35 vs. Fitter 52 — when to choose:
- 4+ weeks to show, moderate problem: Fitter 35 (gradual)
- Under 4 weeks, significant cover problem: Fitter 52 (aggressive)
- Both available: Some feeders start with Fitter 52 to get initial results, then switch to Fitter 35 to maintain — not confirmed as common practice, flag for community input
Budget Alternatives
- High-protein base feed + reduced energy grains achieves a slower version of this effect
- No commodity equivalent for the concentrated protein level
