Afterburner®
51% protein fat-burning pellet for trimming condition and building muscle definition in over-conditioned show livestock — L-Lysine, probiotics, multi-species including sheep
Always read and follow product labels for feeding and sheep safety.
Overview
Afterburner is Kalmbach’s fat-burning, muscle-definition supplement — a 51% protein pellet designed for show animals that have too much condition and need to be leaned out and tightened up. It directly competes with Kent ShowBoss Fit N Finish (52% protein) and Show-Rite Sculpt (50% protein) in the fat-burning/muscle-definition category. Multi-species labeled. Contains L-Lysine for amino acid balance, probiotics (Lactobacillus, Bifidobacterium, Bacillus), and yeast culture. Packaged in a 20 lb pail.

How Experienced Feeders Actually Use It
Afterburner is reached for when lambs are getting heavy up front or losing muscle expression under a layer of fat. The 51% protein with L-Lysine drives muscle while the very low fat (2.8%) contributes to the trimming effect. Used in the 6–8 week window when there is still time to reshape. Start at 2 oz/day and watch condition; increase to 4–8 oz/day if animals need more aggressive trimming.
Real-World Feeding Rate
- Typical rate: 4–6 oz/day for most show lambs; 8 oz/day for heavily over-conditioned animals
- Introduction timeline: 6–8 weeks out when condition correction is needed

Phase Protocols
Weeks 8–6 | Condition Building Phase
Introduce if front-end condition is already excessive. Start at 2–4 oz/day.
Weeks 5–3 | Fill & Shaping Phase
Increase toward 6–8 oz/day if trimming is still needed. Monitor muscle tone weekly.
Weeks 2–1 | Final Prep Phase
Taper or hold based on presentation. Discontinue if lamb becomes too lean.
Stacking Protocols
Conceptually conflicts with Moonshine Cherry (which adds fat cover) — do not run both at full rates simultaneously. Afterburner pairs well with Opti-Ferm XL for gut health support during a high-protein trimming phase.
Cross-Brand Notes
Direct competitors:
- Kent ShowBoss Fit N Finish — 52% protein fat-trimmer (nearly identical concept)
- Show-Rite Sculpt — 50% protein pellet fat-burner
- Umbarger Star Glo — 40% protein powder fat-burner
Budget Alternatives
- Soybean meal (commodity) — high protein, no fat; much cheaper but lacks the probiotic/L-Lysine stack
