Every herd has that one animal — the hard keeper that drops weight in winter, the senior whose ribs start showing, or the show prospect that just won’t fill out no matter how much grain you pour. Getting the right calories into them without disrupting their rumen is the real challenge, and it starts with choosing a supplement designed for their specific metabolic needs rather than just dumping more corn.
I’m Rikta — the co-founder and writer behind Gadgets Feed. I spend my time comparing the nutritional profiles, fat percentages, and digestibility ratings of livestock supplements so you don’t have to sort through the marketing hype yourself. (And Homer 🐱 supervised the weigh-in from atop the supplement tub, unimpressed by anything under 50% fat).
This guide breaks down the top formulations for putting weight on cattle, horses, and other livestock, with a focus on calorie density and palatability. Whether you are prepping for show season or nursing a rescue back to health, understanding the key specs will help you pick the best beef cattle feed for your specific situation.
How To Choose The Best Beef Cattle Feed
Not all weight-gain supplements are created equal. The wrong formula can cause digestive upset or be flat-out refused by a picky animal. You need to match the supplement’s fat source, calorie density, and form to the specific animal’s age, health status, and feed routine.
Fat Percentage and Calorie Density
The most effective weight gain supplements pack a high fat percentage — often 40% to 99% — to deliver concentrated calories without the bulk of grain. Fat provides more than twice the energy of carbohydrates per gram, which means you can add significant calories without overloading the stomach. Look for supplements that list crude fat content prominently, as this directly correlates to how quickly an underweight animal can regain condition.
Form: Powder, Liquid, or Crumble
Powdered supplements mix easily into grain rations and are ideal for horses and cattle that are already on a consistent feed schedule. Liquid supplements like high-calorie oils can be poured over hay or feed and are often more readily accepted by animals with dental issues or reduced appetite. Crumbles and pellets work well for animals that are accustomed to textured feeds, but some picky eaters may sort them out. The best choice depends entirely on what your animal already eats and how easily they accept new ingredients.
Digestive Support and Gut Health
Adding concentrated fat and calories to an animal’s diet can disrupt the rumen or hindgut if done too quickly. The best supplements include probiotics, prebiotics, or fiber sources to support digestive function during the transition. This is especially critical for senior animals or those recovering from illness, as their digestive systems are already under stress. A supplement that only adds calories without supporting digestion can cause more harm than good.

In‑Depth Reviews
1. Farnam Weight Builder
Farnam Weight Builder hits a sweet spot with its 50% crude fat formulation, delivering more than double the calories per pound compared to standard grain. The powdered form mixes seamlessly into a horse’s regular ration, which means even the pickiest eaters rarely detect it. The inclusion of omega-3 fatty acids from flaxseed meal and stabilized rice bran adds a skin and coat benefit that owners notice within weeks.
This supplement is specifically designed for horses that need to maintain or gain weight without the risk of sugar-induced metabolic issues. At a 4-ounce serving per day, a single 7.5-pound bucket provides a full 30-day supply, making it easy to track intake. The calming energy profile also makes it suitable for performance horses that need extra condition without becoming hot or fidgety.
Customer feedback consistently highlights its effectiveness for senior horses and hard keepers, with many owners reporting visible improvements in body condition within three to four weeks. The high-fat formula is gentle on the digestive system when introduced gradually, and the alfalfa flavor tends to be well accepted across different breeds and age groups. For a straightforward, proven weight gain solution, this is the benchmark.
Why it’s great
- 50% fat delivers rapid calorie density without bulk feeding
- No added sugar protects against metabolic issues
- Omega-3s improve coat condition and skin health
Good to know
- Powder form requires mixing into grain; not for straight hay diets
- Some horses may need gradual introduction to avoid sorting
2. Horse Guard Super Weight Gain
Horse Guard Super Weight Gain stands apart because it is a true 3-in-1 formula that combines full-fat extruded soybeans, a probiotic-prebiotic blend, and a comprehensive vitamin-mineral package in a single granule. This means you are not just adding calories — you are actively supporting the digestive system to absorb those calories more efficiently. The extruded soy provides a high-quality protein source that helps build topline muscle alongside fat gain.
Each 10-pound bag delivers approximately 20 servings for a 1,000-pound horse, and the included scoop makes dosing consistent. The 1,500 IU of Vitamin E per serving provides immune support, which is especially valuable for stressed, recovering, or senior animals. The granule form is easy to mix into feed and has a palatable profile that even picky eaters tend to accept without hesitation.
Owners of rescue horses and ex-racehorses report that this supplement delivers faster results than standalone fat supplements, likely due to the probiotic component improving gut health. The formula has been trusted since 1978, and the manufacturer’s customer support is noted for being responsive. The only downside is that the bag can go stale if not stored in an airtight container, so transferring to a sealed bucket is recommended.
Why it’s great
- Probiotics and prebiotics improve nutrient absorption
- Extruded soy builds muscle as well as fat
- High Vitamin E content supports immune function
Good to know
- Requires airtight storage to maintain freshness
- Serving size is larger than some pure fat supplements
3. PetAg Dyne
PetAg Dyne is a high-calorie liquid nutritional supplement designed for all classes of livestock, from cattle and horses to goats, pigs, and even dogs. Its liquid form makes it uniquely suited for animals that are reluctant to eat, recovering from illness, or dealing with dental problems. The high-fat, low-volume formulation means you deliver a dense energy source without filling the stomach with bulk.
The gallon jug provides enough supplement for multiple animals or extended use with a single animal. It can be poured directly over grain, mixed into feed rations, or even syringed for animals that are not eating at all. The added vitamins help fill nutritional gaps during periods of stress or recovery, and the formula is designed to be safe for animals from weaning age through adulthood.
Farmers and show competitors alike praise Dyne for its ability to quickly improve body condition in underweight livestock. One user reported taking a pig from severely underweight to a competitive 214 pounds for show fair using twice-daily dosing. The product is also significantly cheaper through Amazon compared to feed store or veterinary supply prices, making it a cost-effective choice for multi-animal operations.
Why it’s great
- Liquid form works for sick, old, or non-eating animals
- Approved for multiple species including goats and pigs
- High calorie density in a small volume
Good to know
- Some animals need a gradual introduction to the taste
- Shake well before each use to ensure consistent dosing
4. DAC Bloom
DAC Bloom delivers a high-fat formula at a price point that makes it accessible for owners managing multiple hard keepers. The 5-pound bag is compact but concentrated, and users consistently report that even notoriously picky eaters accept it without hesitation. The supplement is designed to support weight gain while also enhancing coat shine and skin health, making it a popular choice for show barns.
Many owners switch to DAC Bloom from more expensive brands like Platinum Performance, noting that the results are comparable at a significantly lower cost. The powder mixes cleanly into grain rations without leaving a greasy residue, and the palatability means less waste from animals sorting out their feed. Senior horses and those with reduced appetite seem to respond particularly well to this formulation.
The main consideration is that the 5-pound size may not be the most economical for long-term use with large animals, as buying a larger bulk size directly through alternative suppliers can reduce the per-pound cost. However, for owners who need a reliable, high-fat supplement that their animals will actually eat, DAC Bloom is a strong contender that punches above its price tier.
Why it’s great
- Very palatable — even picky eaters accept it readily
- Adds noticeable coat shine alongside weight gain
- Competitive price compared to premium brands
Good to know
- Smaller bag size may not be cost-effective for large operations
- Larger quantities available from other retailers at better value
5. Formula 707
Formula 707 has been a trusted name in equine nutrition since 1948, and the Weight Gain Crumble formulation continues that legacy. Unlike pure fat supplements, this crumble provides a balance of vegetable fat for digestible calories and high-quality protein for muscle development. The result is weight gain that includes improved topline and muscle tone, not just a fat layer over the ribs.
The crumble form is distinct from pellets, offering a texture that horses tend to find highly palatable. Users report that even horses that have struggled with weight for years start showing improvement within weeks of adding Formula 707 to their ration. The inclusion of fiber helps keep the digestive system functioning smoothly during the transition to a higher-calorie diet.
Senior horses and miniatures are particularly well served by this formula, as the crumble is easy to chew and digest. Owners of extremely hard keepers who have tried multiple other supplements often cite Formula 707 as the only product that actually delivered. The 7-pound bag provides a solid trial period, and the manufacturer’s Colorado-based production ensures consistent quality.
Why it’s great
- Protein and fat combination builds muscle, not just fat
- Highly palatable crumble texture
- Proven track record since 1948
Good to know
- Not a pellet — crumble texture may be unfamiliar to some horses
- Requires consistent feeding schedule for best results
6. Manna Pro Cool Calories 100
Manna Pro Cool Calories 100 is essentially pure fat — 99% fat content — making it the most calorie-dense option in this lineup. This concentrated energy source provides more than twice the calories of an equal weight of carbohydrates, meaning you can deliver substantial energy without increasing feed volume. The “cool energy” profile means it provides sustained, focused energy rather than the hot, fizzy response some grain-based supplements cause.
This supplement is specifically designed for hard-keeping horses, seniors, and performance animals that need extra condition. The fatty acid profile supports glossy coat condition and healthy skin, which owners of older horses particularly appreciate. At 8 pounds, the bag offers a good trial period, and the dry form is shelf-stable and easy to store.
Owners of horses in their late twenties and thirties report that Cool Calories has been the key to maintaining body condition when nothing else worked. The sweet flavor profile is highly palatable without adding sugar, which is a genuine engineering achievement. It is also a cost-effective option for those who need a pure calorie boost without the additional ingredients found in multi-purpose supplements.
Why it’s great
- 99% fat provides maximum calorie density per serving
- Cool energy profile — no sugar highs or behavioral changes
- Supports coat and hoof health with fatty acids
Good to know
- Primarily a fat supplement — lacks protein for muscle building
- May need to be paired with a vitamin-mineral balancer
7. DAC Oil
DAC Oil is a liquid fish oil supplement that delivers a powerful dose of omega-3 and omega-6 fatty acids alongside its calorie content. While it is effective for weight gain, its primary strength lies in improving skin health, coat condition, and joint mobility. Owners of horses with itchy skin, stiff joints, or dull coats report transformative results within a few weeks of adding this oil to their animal’s diet.
The liquid form makes it easy to pour over feed, and the gallon size provides excellent value for multi-animal households. Unlike some fish oil products that horses reject, DAC Oil has a palatable profile that most animals accept readily. The added Vitamin E acts as a natural preservative and provides additional antioxidant support for aging or stressed animals.
Some users note that the oil can cause weight gain as a side effect even when that is not the primary goal, so it is best suited for animals that need both conditioning and skin/coat support. The liquid can be messy if not dispensed carefully, and using a quality pump is recommended to avoid leaks and waste. For owners dealing with a horse that looks dull despite adequate nutrition, this is the targeted solution.
Why it’s great
- Omega fatty acids dramatically improve coat and skin condition
- Supports joint health and digestive regularity
- Highly palatable liquid form
Good to know
- Can cause unintended weight gain in easy keepers
- Liquid form requires careful dispensing to avoid mess
