SPILLERS Stamina+ Cubes 20kg – Low Starch Super-Fibre Performance Feed

Spillers Stamina+ Cubes – 20kg

Endurance riding poses a specific nutritional problem: the horse needs hours of usable energy, but the cereal starch that supplies it quickly also makes the horse sharp and upsets the hindgut. Stamina+ Cubes answer it by moving the energy into fibre and oil — 19% fibre, 6% oil, and 11.5 MJ/kg of digestible energy.

It is molasses free, with sugar down at 3% and starch at 11%, and Spillers include probiotic live yeast and prebiotic oligo-fructose to keep the hindgut working through long, hard days. Wheatfeed, dehulled soya bean hulls, oatfeed, sunflower seed meal and rice bran do the work; there is no whole cereal grain in the list.

Performance & Benefits

• 19% fibre and 6% oil at 11.5 MJ/kg — endurance energy that does not arrive as a starch spike.
• Molasses free, with sugar at just 3%.
• Starch held to 11%, low for a feed of this energy density.
• Probiotic live yeast with prebiotic oligo-fructose for hindgut health.
• 13% protein for muscle maintenance and topline through a long season.
• Vitamin E at 500 iu/kg with 0.3 mg/kg selenium for antioxidant cover.
• Cubed rather than mixed, so a horse cannot sort out the bits it likes.

Suitable For

• Endurance horses, eventers and horses in medium to hard work.
• Horses that turn sharp on cereal-based mixes.
• Horses needing sustained energy over distance.
• Performance horses with sensitive digestive systems.
• Not for a laminitic or insulin-resistant horse at 11% starch — Spillers Speedy-Mash Fibre is the low-starch feed we stock for those.

Feeding

• 500kg horse in medium work: 3.5kg a day, split across at least two meals.
• 350kg pony in medium work: 2.5kg a day, split across at least two meals.
• Feed alongside ad-lib forage and adjust to condition and workload.
• Introduce gradually, as with any new feed.
• Clean, fresh water at all times.

• Typical analysis: digestible energy 11.5 MJ/kg, protein 13%, oil 6%, fibre 19%, starch 11%, sugar 3%.
• Vitamins and minerals: A 11,000 iu/kg, D3 1,500 iu/kg, E 500 iu/kg, selenium 0.3 mg/kg, copper 35 mg/kg, zinc 130 mg/kg.

• The only certification mark Spillers show for Stamina+ Cubes is BETA NOPS. Claims of natural or bio-available vitamin E appear on some retail listings; Spillers publish no such distinction, so none is made here.

Care & Caution

• At 11% starch this is a performance feed, not a laminitis feed. It is not suitable for a horse or pony with laminitis, EMS or diagnosed insulin dysregulation.
• Cut the ration back on rest days. A full performance ration fed to a horse standing in is a recognised risk factor for tying up.
