The Microbes

Four Native Rumen Microorganisms

Four proprietary, native rumen microbes sourced from elite high-producing cows. Each contributes discrete metabolic pathways, but their dominant mode of action emerges from community-level interactions that reshape the rumen microbiome.

The Research

Performance Validated by Leading Dairy Research Institutions

Our rumen-native microbial technologies were developed and evaluated in collaboration with leading academic and independent dairy researchers. Across more than 12 independent controlled research trials, these studies have helped design and validate microbial strains that support rumen fermentation and dairy cow performance.

Following academic validation, our microbial programs were tested in commercial dairy systems through controlled on-farm treatment vs. control trials. To date, these evaluations have included more than 60,000 cows across over 60 commercial trials.

Academic Trials

The studies below evaluate Galaxis™ Frontier, our full microbial program, across nine independent university-led trials conducted throughout the lactation curve. These controlled studies examined the effects of daily supplementation on milk production, feed efficiency, and lactation persistency. Access to the peer-reviewed manuscripts and trial details is provided for each study below.

Dr. Alfonso Lago:
40-week trial : avg starting 50 DIM
+8 lbs ECM, +2.8 lbs DMI, +0.04 pts FE
Holstein study where lactating dairy cows were started on Galaxis 1.0 or Galaxis Frontier early in their lactation. Production and efficiency effects were tracked while cows were fed product for the following 40 weeks of their lactation. Here, we saw a more persistent lactation curve from cows fed Galaxis Frontier daily over their lactation.

20-week trial: avg starting 61 DIM
+4.4 lbs ECM, +0.4 lbs DMI, +0.08 pts FE
Holstein study that observed an increase in milk yield, ECM, milk fat, and milk total solids, as well as improved feed efficiency for Galaxis 1.0 and Galaxis Frontier. A second manuscript is in preparation, which will include additional analyses on digestibility, changes to the rumen microbiome, and analysis of metabolic biomarkers.

Dr. Mike Vandehaar:
16-week trial : avg starting 90 DIM
-0.9 lbs ECM, -1.8 lbs DMI, +0.04 pts FE
Holstein study where cows were started on Galaxis Frontier (label dosage or increased dosage) starting mid-lactation and followed while fed product for 20 weeks. These cows did not show large production gains (in line with the lactation stage-specific effects identified in our study with Dr. Drackley), but they did show trending improvements in feed efficiency due to decreased dry matter intake.

Holstein study that observed improved production and efficiency from cows fed Galaxis 1.0 or Galaxis Frontier; importantly, this study also highlights a correlation between the magnitude of production effects & the stage of lactation in which a cow starts on Frontier.

20-week trial: avg starting 105 DIM
-0.7 lbs ECM, -1.1 lbs DMI, +0.03 pts FE
Holstein study where cows were blocked into five pairs of pens based on their starting DIM, with treatment pens delivered Galaxis Frontier daily through the TMR for the following 20 weeks of the lactation. Production, intakes, and milk composition were measured. Manuscript in preparation.

Dr. Johan Osorio:
3 weeks closeup + 16 weeks lactating : avg starting -21 DIM
+3.75 lbs ECM, +1 lbs DMI +0.11 pts FE (milk/DMI)
Holstein study where treatment cows were started on Galaxis Frontier approximately 3 weeks before calving and continued daily feeding through 16 weeks in milk. The cows fed Galaxis Frontier showed trending improvement in ECM compared to control cows, driven by milk yield increases that were strongest post-fresh (+9 lbs/day/cow milk yield). Component concentration differences between control cows and those fed Galaxis Frontier were not found to be statistically significant, nor were differences in intake. Feed efficiency (milk yield/intake) tended to be higher overall (+0.11) in cows fed Galaxis Frontier and was significantly higher (+0.18) during post-fresh production.

Dr. Jimena Laporta:
Prepartum through early lactation : avg starting -28 DIM
+4.5 lbs colostrum, +0.99 lbs protein, +5.96 lbs calf weight
Holstein study utilizing 60 dry, pregnant multiparous cows to evaluate the effects of prepartum Galaxis Frontier supplementation on colostrum outcomes. The experimental design combined two control groups into a single “Control” group (n=40) that did not receive the supplement before calving, compared to the “Frontier” group (Pre+PostG, n=20) that did receive the prepartum treatment. Cows receiving Galaxis Frontier produced significantly more colostrum with higher protein content, and their calves were heavier at birth. The study also examined mammary tissue, finding 20% more alveoli, 10% more mammary epithelial cells, and a 30% reduction in cell apoptosis in treated cows.

Dr. Kyle Thompson:
Prepartum through calving : avg starting -21 DIM
Colostrum outcomes: +2.4 lbs yield, +1.05% fat, +54 g IgG
Holstein study conducted on a commercial 6,500-cow California dairy evaluating prepartum Galaxis Frontier supplementation on colostrum outcomes. Cows entered the close-up pen approximately 21 days prior to calving and were assigned to treatment or control pens based on ear-tag ID (odd = treatment, even = control), with four pens per treatment. Treatment pens received the standard close-up ration supplemented with Galaxis Frontier, while control pens received the same ration without supplementation. Colostrum outcomes were evaluated from a random subset of mature cows per group. Cows receiving Galaxis Frontier produced significantly more colostrum (+2.43 lbs; p = 0.03) with greater fat concentration (+1.05%; p = 0.007) and higher fat yield (+0.33 lbs; p = 0.0013). Protein and IgG measurements were numerically higher but not statistically different between groups.
