A History of Performance...

At Stewart's Duroc Farm, our genetic emphasis has always been on improving pig performance. Since we started raising Durocs in 1942, it has been our goal to produce high performing boars and gilts that would work in the commercial industry and for other purebred breeders. Sticking with this philosophy for over 60 years has brought great results. Purebred breeders, breeding companies and commercial producers from all over the world have visited our farms and purchased genetics.

Stewart's Duroc Farm and Stein and Stewart Genetics currently produce Duroc, Yorkshire, Hampshire and crossbred boars and gilts. We farrow year-round for a continuous supply. Our pigs represent some of the elite genetics available in the world today. Sound, durable, heavy muscled boars with tremendous performance are available. Our gilts are sound, structurally correct and productive. We have been measuring 21 litter weights on all our litters since 1976.

You are invited to visit one of our farms to personally select your breeding stock or we can do it for you and deliver the animals on approval. All animals are fully guaranteed.

We are very proud of the fact that our genetics have been used to improve the performance of swine throughout America and the world.



Commercial semen is available from our current herdsires that we have retained for semen sales. New young sires are kept often so semen from the latest, most genetically advanced boars is available. All semen is PRRS and PRV free. Volume commercial contracts are available and semen is priced around $6 per dose. Prices do not include delivery or shipping.


Swine producers from around the world looking for high health, high quality, large selection and the best performance records in America come to Stewart's Duroc Farm in Waverly, Iowa, and Stein and Stewart Genetics in Odessa, Missouri.

All the Durocs, Yorkshires and Hampshires we produce are pedigreed through the National Swine Registry (NSR) in West Lafayette, Indiana. All pedigrees can be transferred to purchaser if requested at the time of purchase.
