Watching your horse struggle to maintain weight despite endless meals is genuinely heartbreaking. You want that gleaming coat and lively energy back without the risk of grain-induced heat or colic.
I’m Mo Mahin — the founder and writer behind Furric. I’ve spent countless hours analyzing equine nutritional science, evaluating veterinary safety protocols for fat digestion, and scouring feedback from dedicated stable owners to find what truly works for hard keepers.
This guide reveals the best high fat horse feed choices based on rigorous ingredient analysis and real owner feedback for optimal health.
How To Choose The Best High Fat Horse Feed
Buying horse feed is not just about grabbing the bag with the highest number. You need to consider your horse’s specific workload, metabolism, and any underlying health conditions. A high fat feed can transform a ribby rescue into a glossy powerhouse, but only if you pick the right formula.
Fat Content & Calorie Density
Look for feeds with a crude fat percentage above 20%. Fat provides more than twice the calories of an equal weight of grain or hay, allowing you to boost energy intake without filling your horse up on bulk. This is especially critical for seniors or horses with reduced gut capacity.
Palatability & Ingredients
A feed is useless if your horse refuses to eat it. Ingredients like flaxseed meal, coconut oil, and rice bran not only boost fat content but also add natural flavor and smell that horses love. Avoid feeds that rely heavily on added sugar or molasses to mask poor-quality ingredients.
Overall Health Support
The best high fat feeds go beyond calories. Look for added probiotics to support digestion during weight gain, vitamin E as a natural antioxidant for the extra fat in the diet, and omega fatty acids for coat and hoof health. A holistic supplement supports lasting results.

1. Horse Guard Super Weight Gain 10 lb
This 3-in-1 formula is exactly what hard keepers and seniors need. It combines full-fat extruded soybeans, a robust probiotic package, and essential vitamins into one powerful supplement that targets weight, coat, and digestion simultaneously.
The extrusion process makes the soy highly digestible, meaning your horse can actually absorb the nutrients without overworking their sensitive digestive system. It also includes prebiotics and yeast to support gut health, which is often compromised in underweight horses.
If you are looking for visible topline improvement and a shiny coat in a single bag, this is your best bet. It is trusted by rescue organizations for rehabbing starved horses because it delivers rapid, safe results without causing metabolic upset.
Why we love it

2. DAC Oil Gallon Jug
Sometimes the simplest approach is the most effective. Pure fat supplementation with added Vitamin E offers a direct path to weight gain and a stunning coat without altering your horse’s existing grain ration.
Fish oil provides essential DHA and EPA fatty acids, which are powerful anti-inflammatories that support joint health and overall immunity. The added Vitamin E acts as an antioxidant to protect the fats from oxidation inside the body.
It is an easy, mess-free addition to any feeding routine. Owners report significant improvements in coat glossiness within weeks of adding this oil to their horse’s daily feed.
Why we love it

Farnam has created a powerhouse formula with 50% crude fat, providing more calories per pound than grain without the sugar spike that leads to unwanted energy or metabolic issues.
The inclusion of flaxseed meal and heat stabilized rice bran delivers omega-3s for that glossy coat while promoting calm, focused energy. This makes it an excellent choice for performance horses that need weight but tend to get hot on grain.
It is a stellar choice for owners wanting maximum fat intake without a premium price tag. The powder mixes easily into a mash, making it ideal for seniors with dental issues.

Because it provides cool energy, it is excellent for performance horses who need weight but tend to get hot or fizzy on grain. The highly palatable formula means even picky eaters will clean their bucket.
For underweight horses who struggle to finish their grain, this concentrated source is a lifesaver. A little goes a long way, making this one of the most cost-effective options on the market today.

A trusted name for over 25 years in the equine world, this oil is a fantastic daily topper for overall health and shine. It is unflavored so it blends well with any feed.
Why we love it
- Unique blend of coconut and soybean oils

Safety & Care Tips
Proper Storage is Key
Opened bags of high fat feed and oil bottles are susceptible to rancidity. Always store them in a sealed container placed in a cool, dry area away from direct sunlight. Rancid fats not only taste bad but can cause digestive upset or vitamin deficiencies in your horse.
Monitor Body Condition
Adjust the feeding amount based on your horse’s actual workload and body condition score. A high fat diet can lead to obesity if not managed carefully. Weigh your horse or use a condition scoring chart every two weeks to ensure you are hitting the sweet spot with your supplementation.
