Sustainable Stock: Reviving Legacy Genetics

Episode 27: Volatile Markets, Reliable Cattle with Chengetai Mukosera 
-Full video episode available on YouTube-
What happens when unstable markets force you to rethink what actually holds value?
In this episode, we sit down with Chengetai Mukosera of Zimbabwe, an accountant turned cattleman who entered the industry with spreadsheets and theory, only to have real world conditions reshape his entire approach. 
Starting with Simbrah in a commercial system, Chengetai quickly began noticing a pattern. Taller, later maturing cattle struggled to hold condition, delayed reproduction, and required more input to maintain. Meanwhile, moderate framed, adapted cattle were quietly outperforming them where it mattered most, fertility, efficiency, and survival under pressure.
From there, the conversation turns practical.
We discuss selection for fertility, visual indicators like sexual dimorphism, and how environmental pressure, from seasonal forage swings to tick load, forces honest decisions. In a system where inputs are limited, cattle either function or they do not.
As Boran cattle began outperforming in his environment, Chengetai redefined what improvement meant. Not more growth, but less work. Not bigger cattle, but better cattle.
We also touch on the loss of local Mashona genetics, the push toward larger carcasses, and the long term consequences of selecting for market signals instead of biological function.
At its core, this episode highlights a simple reality.
Profit is not created at the market. It is built into the cow, and lives in the herd.

Episode 26: The Gap Between Function and the Show Ring
-Full video episode available on YouTube-
What happens when the traits rewarded in the show ring drift away from the traits that keep cattle productive in the pasture?
In this episode, Patrick Powers is joined by Grant Vassberg and John Atkinson to discuss Grant’s recent trip to Thailand, where he judged cattle and got a firsthand look at how show ring priorities influence breeding decisions.
The experience sparked a broader conversation about how selection pressure shapes cattle populations over time. When breeding decisions begin to prioritize appearance, trends, or marketing, the traits that matter most in the pasture such as fertility, efficiency, structural soundness, and longevity can slowly fall out of focus.
From there, the discussion widens to examples from around the world including the Philippines, Brazil, and Australia, where industry incentives and breeding trends have pushed cattle in very different directions. Again and again, the same pattern appears. When selection pressure moves away from biological function, producers often end up compensating with more inputs, more management, and lower overall fertility, ultimately draining profit from the operation.
At its core, this episode explores the growing gap between what is rewarded in the show ring and what actually works in real production environments.

Episode 25: Panama’s Fertility Paradox with Roderick Murray
-Full video episode available on YouTube-
What happens when a country selects cattle for trophies instead of calves?
In this episode, we sit down with Dr. Roderick Murray to unpack hard numbers, hard lessons, and a practical path back to fertility and profitability on grass. Drawing from herd-level observations and long-term production data, we discuss why birth rates have remained stuck between 35 and 60 percent, why age at first calving has stretched past 42 months, and why steers often take more than three years to finish, even as nutrition and management improved.
Roderick explains how a 1990s push for larger frames and heavier carcasses, reinforced by show ring culture and a government backed sire program, unintentionally selecting for later maturity, contributed to cattle that struggle outside high input systems. The result has been declining fertility, calving challenges, udder issues, and animals that perform well on paper but fall short under real pasture conditions.
We also talk about what is changing. Research and producer herds in Panama are re evaluating local Creole genetics for early maturity, fertility, and adaptation, then using thoughtful crossbreeding, including Nelore, to improve reproduction and calf vigor without increasing inputs.
The solution is not always imported. Often, it is already adapted to the environment and available right in your backyard.
If you care about cattle that work where they live, this conversation offers data, perspective, and a clear look at how incentives shape outcomes.

Episode 24: Matching Cattle to Country with Matt Robbins 
What if the fastest path to profit is choosing cows that match your weather, then letting grass lead the schedule? We sit down with Matt Robbins to unpack how his family left hay dependence, heavy inputs, and misaligned genetics behind and built a resilient, profitable herd for hot, humid Arkansas.
Matt explains why management and genetics have to move together. We dive into a Mashona-led composite built for heat, humidity, and parasites, paired with a 45-day breeding season and Zietsman’s two-three standard that selects for true fertility under pressure. On the ground, ultra-high-density grazing includes about four moves a day at up to a million pounds per acre. This approach drives uniform utilization, deeper rest, stronger stockpiles, and fewer days feeding hay. We talk practical numbers from cow size to supplemental protein costs, and how rotating by recovery, not the calendar, keeps forage quality and animal performance aligned.
This conversation tackles myths head-on. We discuss why EPDs fade across environments, how warm-season forage often labeled “poor” can support excellent production with the right cattle, and where a one-time amendment can ethically and profitably jump-start a tired pasture. The unexpected wins are everywhere. Soils become spongier, native grasses return, drought resilience improves without destocking, and wildlife and water quality benefit as the land breathes again. If you’re curious how to run more cows on the same acres, reduce inputs, and buy back your time with a tight calving window, this is your playbook.

Episode 23: Small Acreage, Big Results with Joseph Klotz 
What if a 12-acre ranch could outlast drought, dodge input spikes, and still raise fertile, gentle cattle that pay their way? That is the story Joseph Klotz tells from Seely, Texas, a rancher who proves you do not need a thousand acres or a show banner to build a profitable, resilient herd. We dig into how his family’s weekend Brahman operation shaped a lifelong filter: if a cow cannot calve, rebreed, and stay sound without help, she does not stay.
Joseph breaks down his three F’s: function, fertility, and friendly, and shows why moderate-frame cows can deliver more pounds per acre with less risk than giant frames ever could. He walks us through the pivot to regenerative grazing: tighter rotations, long rest, and three years with no synthetic fertilizers, herbicides, pesticides, fungicides, or wormers. The results are tangible and repeatable: deeper roots, more earthworms, cooler soil, minimal flies, and grass that carries through dry spells while neighbors feed hay.
We also explore the move to Red Brahman for dual-purpose advantages, the reliable tenderness and flavor of calves raised on forage and mama’s milk, and the power of strict culling for soundness and temperament. On the business side, Joseph shares a practical approach to profitability: track cost per exposed cow, leverage direct-to-consumer beef, and use old-school, low-cost tools from pickup stock racks to a modified rotary mower to keep margins wide and debt light. Mentorship, windshield time, and a relentless “what and why” mindset tie it all together.
