The 7 Golden Rules Of Feeding Horses
How should I feed my thin horse?
Data basis: This report aggregates feedback from dozens of written reviews and several video demonstrations collected between 2018–2025. Most feedback came from written reviews, supported by video clips and buyer Q&A posts, with a mix of recent and older buyer experiences.
| Outcome | UltraCruz Equine | Typical mid-range |
|---|---|---|
| Weight results | Inconsistent gains reported; some buyers saw little change after weeks. | More reliable results generally expected from mid-range, fortified feeds. |
| Palatability | Mixed acceptance with multiple reports of refusal or selective eating. | Usually neutral flavor in typical oils, so horses accept feeds faster. |
| Packaging | Messy pour and occasional leakage noted during use and storage. | Cleaner dispensing designs are common in comparable bottles. |
| Shelf life | Higher rancidity risk reported after days or weeks open versus expectations. | Longer stability is typical for mid-range oils when stored per directions. |
| Regret trigger | Palatability & rancidity together create the main buyer regret: wasted feed. | Lower regret because typical alternatives balance taste and shelf stability. |
Top failures

Will my horse refuse it because of smell or taste?
Regret moment: Many buyers report the bottle's aroma is noticeable on first pour and can trigger refusal.
Pattern: This is a commonly reported primary issue across written reviews and videos, appearing at first use or after short storage.
Usage anchor: The problem often shows up on first feeding or after the bottle has been opened for a few days.
Category contrast: Most mid-range feed oils are described as neutral-smelling, so this smell feels worse than buyers usually accept.
Does it reliably add weight to my horse?
- Primary pattern: Several buyers report inconsistent weight changes despite weeks of use.
- Early sign: No visible bulking after 2–4 weeks is commonly mentioned as an early indicator.
- Frequency tier: This is a secondary issue—less common than smell problems but more frustrating when it occurs.
- Cause clue: Users tie inconsistent results to short dosing or switching feeds mid-trial, according to multiple posts.
- Fixability: Extended trials or pairing with calorie-dense feeds is a workaround, but that adds cost and effort.
Why is the bottle so messy or leaky?
- Frequent report: Buyers commonly describe drips and leaks when pouring from the gallon container.
- Early sign: Sticky residue around the cap appears after first few pours.
- Impact: Mess leads to wasted product and extra cleanup time in the barn.
- User attempts: Many users switch to a squeeze bottle or use a separate pour spout to reduce spills.
- Hidden cost: Extra funnels or transfer bottles are a common add-on, increasing total expense.
- Category contrast: Compared to mid-range alternatives, this one is less user-friendly for daily barn use.
Does it go bad quicker than expected?
Hidden requirement: Proper storage is a repeated caveat; buyers say cool, dark storage matters much more than expected.
- Persistence: Rancid or off smells are persistent for some buyers after only a few weeks open.
- When it worsens: Warm barn temperatures and long open periods make spoilage appear faster.
- Scope: This appears across written reports and video checks, not limited to one seller batch.
- Workaround: Refrigeration or rapid consumption is recommended but is a hidden requirement many buyers did not expect.
- Why worse: Oils in this price range usually tolerate normal barn storage better, so this product demands extra care.
- Real cost: Needed storage steps or faster turnover create ongoing time and fridge space costs.
- Edge-case: A minority report long stability when stored perfectly, but that is the exception.
Illustrative excerpts

Excerpt 1: "Bottle smelled strong and my mare pushed her feed away immediately."
Note: Reflects a primary pattern of palatability issues.
Excerpt 2: "No visible weight after three weeks despite daily dosing."
Note: Reflects a secondary pattern about inconsistent efficacy.
Excerpt 3: "Cap drips every time; needed a separate pourer to stop mess."
Note: Reflects an edge-case packaging and usability pattern.
Who should avoid this

- Refusal-prone horses: Avoid if your horse is picky; palatability complaints are a leading regret.
- No-fridge setups: Avoid if you cannot provide cool storage, since spoilage risk increases rapidly in warm barns.
- Minimal-mess buyers: Avoid if you need a clean pour, because the packaging often requires extra gear.
Who this is actually good for

- Experienced handlers: Good for people willing to refrigerate and rotate supply to prevent rancidity.
- Supplement experimenters: Works for owners willing to run a longer trial and pair with higher-calorie feeds.
- Cost-conscious buyers: Acceptable if you can tolerate messy packaging and transfer to better dispensers.
Expectation vs reality
- Expectation: Buyers reasonably expect a neutral-smelling oil that mixes easily into feed.
- Reality: Many report a noticeable odor and mixed acceptance on first use, which is worse than category norms.
- Expectation: A gallon bottle should pour cleanly for barn use.
- Reality: The actual experience often requires extra pourers or transfer bottles, adding time and cost.
Safer alternatives
- Choose neutral oils: Pick products labeled for barn stability to reduce palatability and rancidity risk.
- Smaller containers: Buy smaller sizes to avoid long open times and lower spoilage chance.
- Better dispensers: Use a dedicated pourer or pump bottle to prevent mess and waste.
- Trial pairing: Trial with a calorie-dense feed to test effective weight gain before committing to a gallon.
The bottom line
Main regret: Buyers most often regret the combination of smell/palatability and shorter shelf stability leading to wasted product.
Why worse: These issues exceed normal category risk because they require extra storage and cleanup efforts not typical for mid-range feed oils.
Verdict: Avoid if you need a fuss-free, reliably palatable feed oil; consider it only if you can commit to strict storage and extra dispensing steps.
