Sentinel — Guardian of Equine Health

No horse like your horse.

Sentinel® builds purposefully formulated nutrition around the horse in front of you — gutWise™ digestive support, stable vitamins and bioavailable trace minerals, and low-starch recipes across five lines. Every bag is on the floor at Hatchet Farm in Nassau, NY.

Guarded with gutWise™ technology — a Sentinel shield drawn around a horse at pasture, over three pillars: Prebiotics & Probiotics, Bio-Available Marine-Sourced Calcium, and NutriVantage® for Horses.

Why choose Sentinel®?

Purposefully formulated nutrition that addresses your horse’s specific needs.

Digestive Health

To help your horse maintain total digestive and gut health, we use proprietary blends, like gutWise™, and the nutritional power of natural, wholesome ingredients.

Immune Support

Antioxidant nutrients including stable vitamins and biologically available trace minerals help maintain normal health and metabolism.

Whole Body Wellness

To support well-rounded health, our expert nutritionists have crafted specialized formulas that are scientifically designed for whole body equine well-being.

The Sentinel line-up

Pick your Sentinel.

Six families under one shield. Pick a tile to open that part of the line — the story, what makes it different, and every formula we stock. The three feed families also have full guides of their own.

Sentinel 100% Extruded

100% Extruded

The flagship line, and the reason the bag says 100% extruded: every nugget is pressure-cooked from finely ground ingredients into a light, airy shape that breaks down faster and chews easier than a pellet. Horses eat extruded feed more slowly and more thoroughly — which supports a healthier rate of intake, reduces bolting, and may lower the risk of feed-related choke.

Under the hood every formula carries the full Sentinel stack: gutWise™ prebiotics and probiotics, marine-sourced calcium for gastric balance, built-in fiber (soybean hulls, beet pulp, alfalfa meal), “cool” energy from fat and fermentable fiber instead of starch, NutriVantage® research-driven nutrition, and the amino acids, omega fatty acids and trace minerals that carry topline, joints, skin and coat.

  • Light, airy nuggets — easier chewing, slower intake, gentler on the foregut
  • Low starch & sugar across the line — “cool” calories from fat and fermentable fiber
  • gutWise™ + NutriVantage® in every formula
  • Six formulas covering every life stage, foal to retiree

Feed by weight, not volume. Extruded nuggets are far less dense than pellets — the same 2 lb is roughly 2.5 quart-scoops of Sentinel versus 1.5 of a pelleted feed. Weigh your scoop once and mark it.

100% Extruded FAQs

What does “100% extruded” actually mean?

Extrusion pressure-cooks finely ground ingredients with moisture into a light, airy nugget — larger and less dense than a pellet. Kent’s claim: the nuggets encourage slower eating and more thorough chewing, break down faster in the foregut, lower the risk of feed-related choke, and are made with low-starch, low-sugar ingredients.

How much should I scoop?

Feed by weight, not volume: a one-quart scoop holding 2 lb of pellets holds only about 2 lb per 2.5 scoops of extruded nuggets. Weigh your scoop once with your feed and mark it — the guide table above has the comparison.

How do I switch my horse onto it?

Transition over 7–10 days, replacing a little more of the old feed each day. Keep forage and fresh water constant, and confirm the final ration with your vet or equine nutritionist — especially for metabolic horses.

Sentinel Extruded Textured

Extruded Textured

For horses — and horse people — that want a textured feed, this is the textured feed done the Sentinel way: “a complete line of specialized textured feeds which combine low-starch ingredients with fat, fermentable fiber, and exclusive extruded nuggets.” Shredded beet pulp is built into the bag, so the fiber comes with the feed instead of being soaked in a separate bucket.

The beet pulp, soybean hulls and alfalfa meal “may help maintain healthy hindgut fermentation while providing extra calories in a safe and natural form” — performance calories without the starch load of a classic sweet feed, with gutWise™ and NutriVantage® carried in the extruded nuggets.

  • Real texture with built-in shredded beet pulp — no separate soaking
  • Low-starch ingredients + fat + fermentable fiber = “cool” performance energy
  • Exclusive extruded nuggets carry the gutWise™ technology

Formerly known as Sentinel XT. Kent dropped the XT name — the line is now simply Sentinel Extruded Textured, just like the ribbon under the shield on every bag. Same line, same formulas.

Extruded Textured FAQs

Is this the same as Sentinel XT?

Yes — XT was Kent’s earlier name for this line. Kent has since dropped the XT and brands it simply Sentinel Extruded Textured: exactly what the ribbon under the shield prints on every bag. Same line, same formulas — Fiber Show and Fiber Pro were once XT Show and XT Pro.

Do I need to soak beet pulp separately?

No — the shredded beet pulp is built into the bag, so the fiber comes with the feed instead of being soaked in a separate bucket.

Which textured feed fits my horse?

Open the Situations-to-Solutions chart above — Fiber Pro covers all life stages and hard keepers, Fiber Show is the show-condition formula, and Mare & Foal carries growing foals and lactating mares.

Sentinel Performance Pellets

Performance Pellets

The pelleted side of the line: Carb-Guard runs an exceptionally low maximum of 5.5% dietary starch and 4.5% sugar — the numbers veterinarians ask about first for metabolic horses. Secure pairs high fat and high fiber with a 10% starch / 5% sugar cap for hard keepers, and Growth brings the same pelleted, low-NSC approach to growing horses, lactating mares and show condition.

Both carry gutWise™ — prebiotics, probiotics, marine-sourced calcium and NutriVantage® — and both run a fixed formula, so the gut sees the same feed bag after bag.

  • Carb-Guard: max 5.5% starch / 4.5% sugar — Kent’s lowest-NSC horse feed
  • Secure: high fat + high fiber, max 10% starch / 5% sugar
  • Growth: growing horses, lactating mares and show condition
  • Fixed formulas — consistency bag after bag

Performance Pellets FAQs

Are these feeds low starch?

That’s the point of the line: Carb-Guard runs a maximum of 5.5% dietary starch and 4.5% sugar — Kent’s lowest — and Secure caps at 10% starch / 5% sugar (published values). Check each product page for the full guaranteed analysis.

Which one for a metabolic horse?

Carb-Guard is the one veterinarians ask about first for EMS and Cushing’s horses — bring its guaranteed analysis to your vet and confirm the total ration before switching.

Sentinel Forage Extender

Forage Extender

When hay is short, poor, or priced like gold, Hay Stretcher is the pressure valve: a high-fiber pellet that “may be used to replace up to half the hay in the horse’s diet on a pound-for-pound basis.” The analysis is the same in every bag — balanced calcium and phosphorus, less dust and no mold surprises.

The large pellet slows consumption and supports chewing and saliva production; the small pellet is the same formula for horses and feeders that prefer it. It stretches forage — it doesn’t replace grain, and it shouldn’t be the whole diet.

  • Replaces up to half the hay ration, pound for pound
  • Consistent analysis, less dust, no mold surprises
  • Large pellet slows intake; small pellet, same formula

Hay math: a 50 lb bag stands in for 50 lb of hay — roughly a bale. Swap gradually over 7–10 days, and keep at least half the forage as real hay or pasture.

Forage Extender FAQs

How much hay can it replace?

Up to half the hay in the diet, pound for pound — one pound of pellet for one pound of hay. Swap gradually over 7–10 days.

Can Hay Stretcher be the whole diet?

No — it’s not a complete feed and it doesn’t replace grain. Keep at least half the forage as real hay or pasture.

Sentinel Care Supplements

Care Supplements

“Supplements designed with a solution in mind.” Sentinel Care is the targeted end of the line — pelleted supplements that each do one job, fed alongside the ration rather than replacing it: gastric health, immunity, hooves, easy-keeper calories, omega fat, and vitamin–mineral balance.

They address what Kent calls “developmental, physiological, digestive, metabolic or performance concerns” — the horse that needs one thing fixed, not a different feed. Pick the concern, add the scoop.

  • One job per bag — targeted support, not another complete feed
  • Fed alongside your existing ration
  • Same Sentinel low-starch, gut-first philosophy

Not sure which one? Gastric trouble → Gastric Support. Hard keeper or dull coat → OmegaTin. Easy keeper on little grain → Simply Lite or a MultiSentials balancer. Ask in store — we feed this stuff too.

Care Supplements FAQs

How do I feed a Care supplement?

Alongside the ration your horse already knows — each Care product does one job and is dosed by the bag’s directions, not fed as a complete feed.

Which one does my horse need?

Start with the situation, not the bag: open the Situations-to-Solutions chart above and match the concern — gastric, weight, immunity, hooves or mineral balance. For an active medical issue, involve your vet first.

gutWise™ Technology

Equine gut health, done right.

gutWise™ is the technology layer inside Sentinel — “a proprietary blend of digestive-supporting ingredients … designed to support equine gut health as part of a complete feeding program.” The horse’s digestive system is complex and sensitive: the gut drives digestion, nutrient absorption, immune support and day-to-day comfort, and stressors like training, travel and routine changes can throw it off balance.

The blend works in four parts. Prebiotics and probiotics “aid in maintaining stable digestive health and microbial fermentation for sustained digestibility, absorption and assimilation.” Marine-sourced calcium — bio-available calcium that helps support gastric pH and overall balance. NutriVantage® for horses — exclusive components that aid nutrient availability, support a healthy gut environment and offer immune support. And where many supplements focus only on the hindgut, gutWise is built for whole-tract support — balance through the entire digestive tract as part of the daily ration.

A supported gut lets a horse hold consistent intake and digestion, make better use of its nutrients, stay comfortable through routine and seasonal changes, and perform at its peak. You don’t buy gutWise™ separately: it’s built directly into Sentinel feeds — for most horses, no separate gut-health supplement is needed for everyday digestive support.

  • Prebiotics + probiotics — stable fermentation, sustained digestibility
  • Marine-sourced calcium — gastric pH and balance
  • NutriVantage® — nutrient availability + immune support
  • Whole-tract support — foregut AND hindgut, not hindgut alone

Where to get it: every bag on this page carries gutWise™ — nothing extra to buy. Pick your family above: extruded, textured, pellets or supplements.

gutWise FAQs

What exactly is gutWise™ Technology?

It’s Kent’s built-in digestive-support package — a proprietary blend of prebiotics, probiotics, marine-sourced calcium and NutriVantage® — designed to keep the gut’s microbial balance steady as part of the daily ration. It isn’t something you buy separately: it comes baked into the feed.

Which Sentinel products carry it?

The 100% Extruded line, Performance Pellets, Extruded Textured and select Sentinel Care supplements all carry gutWise built in — look for the mark on the bag. If your horse eats Sentinel, the gut support is already in the scoop.

Does it work on the hindgut too?

Yes — Kent designed gutWise to support digestive balance along the whole gastrointestinal tract, hindgut included, not just the stomach.

So does my horse still need a separate gut supplement?

For everyday digestive support, usually not — that’s the point of building it into the feed. Kent’s exception is horses with specific challenges: ulcer-prone animals, frequent travellers and hard campaigners may still benefit from Sentinel Care Gastric Support fed alongside. Your vet knows your horse best.

Pelleted vs. extruded

Light, airy nuggets for improved digestibility.

Extrusion takes our high quality, finely ground ingredients and pressure cooks them with moisture into airy nuggets. They’re lighter, larger and have more volume than pellets, encouraging a healthier rate of intake. They also break down much easier, lowering the risk of feed-related choke and certain digestive upsets.

Before you buy

Straight answers.

Which Sentinel line is right for my horse?

100% Extruded is the everyday answer for most horses — six complete feeds from foal to retirement. Extruded Textured suits horses that do better on a textured feed, including growing foals and lactating mares. Performance Pellets are the low-NSC pick for metabolic-sensitive horses, plus Growth for young stock. Forage Extender stretches hay, and Care Supplements target one job each, fed alongside the ration.

The bag prints its line right under the Sentinel shield — and each family’s own FAQs live on its tab above. For ration specifics, your vet or equine nutritionist has the final word.

How fresh is the feed?

We keep Kent Blue Seal orders flowing constantly, so bags turn over fast — from the mill to our floor to your barn, not months in a warehouse. That steady rotation is also how we handle special orders: if Kent Blue Seal makes a formula we don’t keep on the floor, ask and we’ll add it to an upcoming order — and if you buy it regularly, we’ll start stocking it for you.

Can you deliver it?

Yes — we run our own farm delivery within about 30 minutes of a Hatchet store, free over $300, with weekly to seasonal standing orders. Or order online for same-day pickup in Nassau. Open a farm account →

My horse has Polysaccharide Storage Myopathy (PSSM) — where do I start in the Sentinel line?

Horses with PSSM are typically managed on a low-starch, low-sugar diet, and that’s the design brief behind several Sentinel formulas. Kent’s nutrition team points owners to its low-NSC options — Performance LS and Senior on the extruded side, and Carb-Guard, which carries the lowest starch guarantee in the line (5.5% max). PSSM management is individual, so have your vet sign off on the final ration.

My senior has Cushing’s and insulin resistance. Can he stay on Sentinel Senior, or should I go forage-only?

This comes up a lot, and Kent’s own nutrition team fields it too — their guidance is that Sentinel Senior’s controlled starch and sugar make it a solid fit for metabolic horses, and that a program that’s keeping the horse well doesn’t need changing. Because Cushing’s and insulin resistance vary in degree and shift over time, this is one to manage with your vet: they’ll tell you if and when a forage-based or lower-starch approach makes sense for your horse.

Can a horse with worn-down teeth still eat Sentinel?

This is what the extruded nugget was designed for — it breaks down with very little chewing, and it soaks into a soft mash in minutes, which is exactly how Kent’s nutritionists recommend feeding it to horses with poor dentition. For a senior who has also dropped weight, the higher-fat formulas like Performance LS (12% fat) are built to restore condition without leaning on starch. If the chewing trouble is new, a dental check comes first.

What should a good senior feed actually deliver?

Kent builds its senior formulas around four jobs: easy chewing, easy digestion, safe calories and gut support. In practice that means the soft extruded form, starch and sugar kept low, energy drawn from fat and fermentable fiber rather than grain starch, and added digestive support for an aging gut. Sentinel Senior is the retired-horse version; Active Senior keeps the same brief with more working energy.

Is there a right age to switch to a senior feed?

The rule of thumb Kent’s nutritionists use is to go by the horse, not the birthday. The signals that matter: weight getting harder to hold, slower or messier chewing, or needing more grain to keep condition. Many horses land there in their late teens — but their advice for a twenty-year-old thriving on the current ration is don’t change for change’s sake.

My horse came out of winter with less topline. Feed more, or feed different?

Topline is muscle, and rebuilding it takes quality protein and amino acids as much as calories — which is why Kent makes Topline 30, a 30%-protein balancer designed for exactly this. The feeding chart on every Sentinel bag gives target rates by body weight; work up toward them gradually rather than all at once. If the topline doesn’t come back over a few weeks, that’s a conversation for your vet.

How should I feed a broodmare through pregnancy and into lactation?

Kent’s guidance breaks it into stages. Through early and mid-gestation, a mare in good condition usually stays on her normal ration. The demands come late: the foal does most of its growing in the final two to three months, so her protein, vitamin and mineral needs climb — the job Topline 30 is designed to fill without excess calories. In the last few weeks before foaling, the recommendation is to transition onto a lactation-and-growth formula such as Safe Start or Mare & Foal, so she’s settled on it when milk production peaks. Keep your vet in the loop through any pregnancy.

Do ponies and miniatures get their own feeding rules?

Same feeds, smaller math. Sentinel feeding charts scale by body weight, so ponies and minis eat the same formulas at much smaller rates — and the common pitfall is overfeeding, since most are easy keepers. Watch body condition closely and favor the controlled-starch formulas; Simply Lite exists for exactly this animal, delivering full vitamins and minerals at a reduced calorie load.

How do I switch feeds without upsetting my horse’s gut?

Slowly — a horse’s hindgut hates surprises. The standard practice, and what Kent recommends, is to blend a new feed in over 10 to 14 days, shifting the ratio a little each day, and to give major hay changes the same respect. Spring grass is the classic trap: short grazing windows at first, stretched out gradually over several weeks.

General guidance drawn from the feed maker’s published materials and standard horse-keeping practice — not veterinary advice. Your vet or an equine nutritionist should sign off on any ration change.
