Our Philosophy

Agri-King's philosophy is to help the livestock producer get the most out of each pound of feed and each head of livestock through accurate, precise feed analyses and ration formulation.

Our Concept

Del Curley, a retired farmer, who believed there was a better way to feed livestock, founded Agri-King in 1968. He saw the success farmers were having by testing their soil and fertilizing accordingly. He knew farmers' livestock would benefit if their forages and grains were tested and, using those results, a balanced ration was developed. He was right!

Since 1968, Agri-King continues to lead the way in visionary nutritional technology.

Agri-King was the first to:

  • Utilize x-ray technology to analyze for forage minerals;
  • Develop a viable artificial rumen utilized for the digestibility of feedstuffs;
  • Develop analyses for starch;
  • Develop analyses for lignin;
  • Routinely analyze for electrolytes to balance cation/anion ratios;
  • Develop NIR calibration sets for amino acids; and
  • Regularly utilize manure analyses for problem solutions.

Agri-King's main purpose is to improve your herd health through highly fortified and properly balanced diets while increasing your bottom line. Don't be fooled by least cost rations or quick fixes, they may cost you your future.

Assisting with Environmental Concerns

Environmental concerns are becoming a top priority to the farming community and Agri-King has stepped forward to assist the farmers in becoming better stewards of their land.

In Dairy and Beef

Silo-King®, our premier forage and grain treatment, ensures greater digestibility. Improved nutrient digestibility increases available energy for rumen bacteria and milk production and may reduce the amount of feed required to produce milk. Less feed fed results in lower manure production and thus less phosphorus and nitrogen which is a major environmental concern.

In Swine

The dawning of the antibiotic era in animal agriculture brought successful growth promotants and therapeutic feed additives to the farm. After over 50 years of antibiotic use, however, we now realize that low-level feeding of antibiotics will increase the population of single and multiple antibiotic resistant bacteria. Therefore, many antibiotics are no longer effective against certain strains of bacteria.

There is now a move to return some aspects of animal agriculture and human medicine to the pre-antibiotic era. Several years ago, Agri-King's research scientists began exploring effective alternatives to emerging antibiotic resistance issues. This led to the development and release of Agri-King's direct fed microbial feed additives for livestock. These direct fed microbials in return, have spawned a new awareness in the critical role microbes and microbial nutrition play in maintaining animal health and decreasing pathogens associated with food born illnesses at processing. Furthermore these direct fed microbial products do not contribute to antibiotic resistance in pigs, cattle, or humans.

These products have been shown to enhance the population of beneficial bacteria in the gut while significantly reducing the harmful pathogenic population.

Our History

Agri-King...

an idea conceived by farmers...a company developed by farmers and, today, owned and operated by its employees for today's livestock producers and related industries.


Del Curley
Founder of Agri-King

DEL CURLEY, a lifetime livestock producer, was 48 when he developed an idea based on the success farmers realized by testing their soil and fertilizing accordingly. That concept, he theorized, should work to balance rations for livestock.

AND...IT DID! The year was 1968.

AGRI-KING'S PHILOSOPHY IS SIMPLE: Help the livestock producer get the most out of each pound of feed and each head of livestock through accurate and precise feed analyses and ration formulation.

CURLEY FOUNDED a company successful primarily because all employees were treated like family and a work environment that stimulated innovation and creativity. In return, these people concentrated on quality, detail, service and results. These principles still prevail and have contributed to our long term sustained growth. Our motivation is the desire to help our clients succeed, and our reward is the pride we feel when we are recognized by them as the leader in animal nutrition and on the farm service.
