Nutri-Bloom Advantage™

Nutri-Bloom AdvantageNutri-Bloom AdvantageTM is a unique combination of ingredients that results in a healthier digestive system so your horses will look and feel better.

  • Expect increased bloom with more muscle tone, better body condition, a shinier coat and improved overall health.
  • Makes it easier for horses to digest and absorb nutrients, which also helps them extract more energy from existing hay in their diet.
  • Horses may benefit from better feed efficiency with up to 15% increase in neutral detergent fiber (NDF) digestibility.
  • Featured in SafeChoice® Senior horse feed.
The Research Behind Nutri-Bloom Advantage™:

Test Parameters: Dr. Josie Coverdale of Texas A&M University, in collaboration with Dr. Emily Lamprecht, an Innovation Development Manager for Cargill Animal Nutrition, conducted a study with the specific purpose of testing the efficacy of a feed additive in mature horses.

  • Twenty-seven geldings were assigned to three treatment groups, 9 horses per trt group, in a randomized block design.
  • Horses were fed whole oats, pelleted feed, or pelleted feed with a proprietary additive blend containing prebiotics and probiotics.
  • Measurements included body weight, body condition score (BCS1; Henneke et al., 1983), % body fat2 (Westervelt et al., 1976), total feed intake, and total fecal output.

Hay, concentrate and fecal samples were analyzed for dry matter (DM), organic matter (OM), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), gross energy, and apparent digestibility of the total diet was determined.3 (Coverdale et al., 2013)

Nutri-Bloom Research Graph

Different superscripts indicate differences (P ≤ 0.05) between treatment groups; an asterisk suggests differences (P = 0.13) between fortified vs. plain pellets – e.g., take 100 horses, 87% of time, we are confident that these results would be replicated.


Treatments elicited differences in apparent digestibility of ADF and NDF dietary components.

The data suggest:

  • Horses fed pellets with the additive blend demonstrated greater (P = 0.13) apparent digestibility of NDF and ADF compared to horses fed pellets without the additives.
  • Using pelleted ingredients vs. whole grains improves digestibility of dietary NDF and ADF components (P ≤ 0.05)
  • There is a numerical change towards improved DM digestibility with fortification compared to unfortified diets.


Overall data supports that horses given the specific additive blend containing prebiotics and probiotics in pelleted concentrate digested dietary fiber, including that in the forage – comprising the bulk of most common equine rations – more efficiently than those eating an unfortified pelleted concentrate plus hay or whole oats plus hay. This improved efficiency meant that they extracted more nutrition from the same relative fiber intake. This is part of the science behind Nutrena’s new exclusive Nutri-Bloom Advantage™ that has been shown to support increases in dietary fiber digestion up to 15% for better health and bloom.
