History of Sydenstricker Genetics
The Sydenstricker story starts with farm machinery, not cattle. Ralph Sydenstricker opened an International Harvester dealership in Paris, Missouri, in 1944. In the summer of 1952, two registered Angus cows with heifer calves came to the family as part of a tractor trade, and a trade magazine feature describes the business as starting from the sale of a Farmall tractor. In 1960 Ralph bought the John Deere dealership in Mexico, Missouri, and the family moved the cattle there.
The Angus program grew under the name Sydenstricker Angus Farms, with Eddie Sydenstricker continuing it and hiring Wayne Kestler as herdsman. In December 1974 the family brought 20 females from Canada to Mexico. The first annual production sale was held in November 1978, selling 141 lots. Later honors include the CAB Beef Commitment to Excellence Award in 1997, the 2001 BIF Outstanding Seedstock Producer award, and a listing among the American Angus Association's Heritage Award winners.
What Sydenstricker Genetics Grows and Raises
SydGen runs a large registered Angus cow herd on fescue-based pastures in Missouri's humid climate. The American Angus Association reports that the cow herd grazes rotationally without grain supplementation, so females must perform on forage. Ben Eggers manages the herd, and the operation uses data heavily: it submits more than 12,000 weights and measurements each year to the Association's Angus Herd Improvement Records system.
The breeding goal is genetics that do many things well rather than one trait at the extreme, and the program has consistently earned Certified Angus Beef premiums. Customers are commercial and registered cattle producers, and the Association reports a repeat customer rate of about 80 percent. That figure suggests buyers see value in the bulls and in the service behind them.
How Sydenstricker Genetics Makes Money
Bull and female production sales
The main revenue stream is selling bulls and females at its annual November production sale, the tradition that began in 1978. In 2025 the fall sale was scheduled for November 22, and the operation also held a spring SydGen Influence Sale on April 15 with guest consignors of bulls and females.
Semen and genetics
SydGen bulls have generated retail semen and certificate sales, and six have each topped $1 million. Marketing proven sires through semen turns a successful bull into income that continues beyond the bull sale, though it depends on the bull's performance and on trust in the program.
Repeat commercial customers
A repeat customer rate of about 80 percent means much of the demand comes from buyers who return. The operation's data reporting and carcass performance records give those buyers evidence for their purchasing decisions.
Farm Insight: What Other Operators Can Learn from Sydenstricker Genetics
First lesson: let data carry the sales pitch. Reporting thousands of weights and measurements each year gives commercial buyers objective numbers, and a documented record of carcass premiums supports bull prices better than a catalog photo does.
Second lesson: build for forage-based conditions. Females that thrive on fescue pastures without grain supplementation suit the environment most Missouri cow-calf producers use. Third, widen the market around the core sale. Guest consignors, a second sale and semen marketing extend the reach of a single herd.
Mexico, Missouri, is home to a cow herd that gets by on fescue and good sense, and to bulls whose semen sales have passed seven figures, which is a better record than most of us have with a savings account. For readers who enjoy farm satire, farm humor, ranch humor and farm jokes, farm.FM is the place to go, and the idea of a family that started with a tractor trade and ended up with a famous bull lineup is exactly its kind of story. Even the cows would agree that was a good deal.
