LMF Digest 911®

  • Best Trait = yeast product ingredients have research backing
  • Worst Trait = unclear at this time how product quality and consistency is ensured

Consider this product if…

  1. You know that your forage quality is poor
  2. You’d like to add a safe, uncomplicated digestive aid
  3. Your horse has a hard time gaining weight and you’re already adding massive amounts of calories to his diet
  4. Your fortified feed product does not already contain yeast products
  5. You’d like to prevent digestive upset during feed changes

Why Review LMF Digest 911?

Digestive aids such as LMF Digest 911 are reasonable supplements for most horse owners to top-dress for the following reasons; they won’t hurt, they might work, and they won’t break the bank. I generally approve of digestive aids like LMF Digest 911, because they are simple, straightforward, and contain ingredients that have been studied by researchers and show promising results (Garber et al., 2020). The LMF Digest 911 uses both a prebiotic (Mannan-Oligosaccaride) as well as a probiotic (living yeast culture) in order to attempt to stabilize 70+ feet of the horse’s digestive tract by promoting the “good” bugs and removing the “bad” bugs. Whether or not this digestive aid produces any meaningful results for your horse will depend on many factors such as current forage quality, current level of nutrition, goals for using, and a little bit of luck.

Company Information & Communication

Rating: 4 out of 5.

I’m going to state up front, that I have been long familiar with both the brand LMF as well as the company that produces the ingredients put into LMF Digest 911. Since I knew their representatives and nutritionists, it was relatively easy for me to get answers to my questions and acquire support materials. It is noteworthy that two highly skilled and experienced PhD nutritionists support this product. When asked to supply 1-3 peer reviewed studies to support product claims, they were able to do so quickly. Two of the four articles sent to me were intriguing. Though both studies were supported in some way by a supplement company, they both included fistulated horses and used strong scientific methods (Jouany et al., 2009 & Medina et al., 2002).

I find the information on their website to be fair and reasonable. LMF Digest 911 is mixed and packaged in a legit mill, so I trust it’s safety and consistency.

As they state on the bag, be sure to always store this product in a cool, dry place as there is supposed to be living organisms in there!

Feeding Directions

Rating: 4 out of 5.

LMF recommends one to two ounce servings per horse per day. There are recommendations for various life stages as well as other species as this product is safe to be fed to cattle, goats, dogs and even fish. Studies that explored the effect of Saccharomyces cerevisiae supplementation in horses used between 4-10 grams per day per horse. Considering that 10 grams is 0.35 ounces and one serving size is 1-2 ounces, it is reasonable to conclude that there is enough actual yeast culture in this product to be relevant . Note that these daily serving recommendations are likely for horses at maintenance with no symptomatic disease, so consider increasing the daily serving if your horse suffers from digestive ailments. Doubling the daily dosage of LMF Digest 911 is safe and reasonable. The only thing that it will harm is your pocketbook.

Ingredients List

Rating: 4 out of 5.

The ingredients list of LMF Digest 911 reveals products known to support immunity and metabolism including the two digestive aids and multiple B vitamins. The yeast products are supported by numerous feeding trials in multiple species, but the necessity and inclusion rate of the B vitamins raises some questions. For example, why add 1 mg of biotin when this B vitamin is known to require 20 mg per day to benefit? They use distillers dried grains as a carrier and include a couple ingredients to stabilize the product while they sit on feed store shelves. All of these ingredients are reasonable.

Distillers Dried Grain with Solubles, Saccharomyces Cerevisiae Yeast Culture, Hydrolyzed Yeast, Choline Chloride, Organic Vegetable Oil, Calcium Pantothenate, Riboflavin Supplement, Thiamine Mononitrate, Pyridoxine Hydrochloride, Folic Acid, Biotin, and Vitamin B12 Supplement.

Guaranteed Analysis

Rating: 4 out of 5.

The guaranteed analysis on LMF’s website is unclear. Under “Regional Formulas” the column says “Typical Analysis” which begs the question, what is a typical analysis? Is it the one ounce scoop or 2 ounce serving? I had to go to the Amazon page to see a bag label that confirmed that it was a 2 ounce serving.

Cost

Rating: 4 out of 5.

Three websites agree (Amazon.com, Farmstore.com, and lmffeeds.com) that you should pay $39.99 for a 5 lb bag. This popular size contains 80 one ounce servings and 40 two ounce servings at $0.50 and $1.00 per day respectively.

How does that compare to other products on the market? Well the FORCO product previously reviewed costs the exact same amount for two ounces, but contains fewer ingredients. Therefore, the LMF Digest 911 may be the better deal especially if you can get it locally at your feed store and do not pay shipping costs.

Summary

Rating: 4 out of 5.

Overall, LMF Digest 911 is a great digestive aid supplement when ingredients, dosage, and cost are all taken into consideration. These products are safe to feed to all horses and won’t break the bank. As with all digestive aids (and all supplements for that matter), I would be very specific about your reason for adding this supplement before you spend $365 per year to feed.
