The Sentinel line-up
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
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.
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.

Retired seniors
The classic senior — high-fiber, low-NSC nutrition in an easy-chew nugget.
100% Extruded FAQs
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.
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.
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
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.
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.
Read the full Extruded Textured guide Open the Extruded Textured pickerAll stages & hard keepers
Performance nutrition for horses of all life stages and hard keepers — the lowest NSC in the textured line.
Show horses
The show formula of the textured line — condition and bloom on low-starch energy.
Foals & lactating mares
Performance nutrition for growing foals and lactating mares — last trimester through weaning.
Extruded Textured FAQs
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.
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.
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
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.
Metabolic horse? These are the two bags to ask your vet about — bring the guaranteed analysis from the product page. NSC figures are Kent’s published maximums.
Open the Performance Pellets pickerStarch-sensitive
For starch- and sugar-sensitive adult horses — max 5.5% starch, 4.5% sugar.
Hard keepers
High-fat, high-fiber pellet — yearlings through seniors, hard keepers included.
Growth & show condition
For growing horses, lactating mares and added show condition — low-NSC energy with biotin for coat and hoof.
Performance Pellets FAQs
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.
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
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.
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.
Open the Forage Extender pickerForage stretch
The classic — large pellet slows consumption and supports chewing.
Forage stretch
Same formula, smaller pellet — easy in any feeder.
Forage Extender FAQs
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.
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
“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.
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
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.
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
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.
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
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.
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.
Yes — Kent designed gutWise to support digestive balance along the whole gastrointestinal tract, hindgut included, not just the stomach.
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.

Before you buy
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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
