Our Technology Story

Innovative Technologies for Livestock & Crops

Ralco’s natural solutions are built to solve real-world challenges for producers with precision and consistency. Backed by decades of research and field testing, our technologies are designed to improve health and performance across livestock and crops.

Protects Beneficial Microbes

Our technologies help safeguard the good microbes animals and plants depend on, supporting digestion, nutrient uptake and stronger defenses against everyday production stress.

Promotes Competitive Exclusion

By feeding the right microbial populations and improving the gut or root environment, our solutions create an environment where beneficial microbes can thrive.

Delivers Targeted Formulations

We match plant-based ingredients to specific production challenges using mapped NEXUS™ profiles. Every solution is built for a purpose, not just a one-size-fits all approach.

Strengthens Natural Immunity

Ralco technologies help reinforce structural barriers in the gut and reduce inflammation, giving animals the internal support needed to fight back and recover faster.

Helps Hosts Prepare for Challenges

Healthier systems, whether in the gut or soil, respond better under pressure. Our innovations promote balance and defense at the cellular level, helping operations stay on track during high-stress periods or challenges.

Consistent Performance

With patented delivery systems, strict quality control and decades of field-proven success, Ralco delivers reliable performance in commercial agriculture, season after season.

Dairy Farmer
Minnesota

800 Head Nursery Operation

Dairy Farmer

“Every Ralco product we’ve ever tried has worked, and that’s rare.”

3,600 Head Sow Operation
Pennsylvania

“Essential-Lyte™ has completely changed the way I wean piglets. I used to battle major issues with pigs going off feed, getting sick and even losing animals, sometimes in over half of my litters. Since using Essential-Lyte, those problems have virtually disappeared. It’s been a total game-changer for my operation. I can’t imagine weaning without it!”

Andy
Pennsylvania

“Weaning time has always brought some health challenges, runny noses, respiratory issues, calves going off feed. But after using Fight Strong® Pellet, everything changed. The calves came to the bunk every day, even through tough weather swings. I didn’t treat a single one of the 140 head that turn. Not having to put a needle in a single calf, that’s worth a lot.”

Dean
Feedlot Iowa

“Mortality during finishing was ranging as high as 8-10% with most cases when my hogs weighed 150 – 300 lbs. Since using Regano® EX, outbreaks have completely stopped.”
