Donor Cows in San Antonio, TX
Our embryo donor cows are carefully selected for superior genetics, strong maternal traits, structural quality, performance, and bloodline consistency. These donor programs are designed to help San Antonio breeders create stronger future generations with confidence — whether you’re hauling embryos back to your place near Leon Springs or starting a new herd out by Medina Lake.
Semen Donor Bulls in San Antonio
Our semen donor bulls represent proven bloodlines selected for strength, performance, longevity, and herd improvement potential. Every sire program is built to support long-term breeding success and genetic advancement.
For ranchers in San Antonio, this matters more than you might think. The climate here — that mix of hot summers and mild winters — demands cattle that can thrive. Our bulls are chosen with those very conditions in mind. We’ve seen breeders from near Loop 1604 drive out to Groveton looking for genetics that actually hold up in Bexar County’s environment. And they keep coming back because the results speak for themselves.
Honestly, if you’re running a operation anywhere around San Antonio, you don’t want just any bull. You want one whose lineage has been tested. Our donor bulls come from bloodlines that have proven themselves in Texas conditions — not just in a show ring but out on real pasture. Whether you’re breeding for meat quality, heat tolerance, or maternal traits, we’ve got the genetics that deliver.
- HORSE BREEDING OPERATIONS
Horse Breeding Operations Guided by Selection in San Antonio
At Casaray Ranch, our passion for excellence extends beyond cattle. Our horse breeding program is built on the same values that define our Red Brahman operation — quality genetics, structural soundness, performance, and careful selection.
We focus on raising horses with strong bloodlines, athletic ability, great temperament, and lasting value, always prioritizing functionality, beauty, and adaptability.

- Future Breeding Programs
If you’re near San Antonio and looking for a horse with real substance, you know the struggle. It’s not easy finding a breeder who understands what actually works on Texas soil. We’ve had folks from Stone Oak all the way down to Southside come through our gates. They want horses that can handle our terrain, our heat, and our way of life. That’s exactly what we deliver.
Our program isn’t about flashy sales pitches. It’s about bloodlines that have earned their keep. We’ve raised horses that work cattle, that ride trails out near Government Canyon, and that hold their own in performance events across Texas. Every mare and stallion in our stable was selected because they bring something real to the table — structure, temperament, and that hard-to-define quality that makes a horse a partner, not just an animal.
- LIVE ANIMAL SALES
Elite Genetics Available from San Antonio Worldwide
Casaray Ranch offers live animal sales designed for breeders, ranchers, and livestock investors looking to strengthen breeding programs with carefully selected cattle and horses. Every opportunity is backed by responsible breeding practices, genetic integrity, and a commitment to long-term livestock value.
Whether you are expanding your ranch, improving herd performance, or investing in future bloodlines, our team is committed to helping you find the right livestock opportunities for your goals.
Here’s the thing about folks from San Antonio: they don’t mess around when it comes to their livestock. We hear it all the time from buyers driving up from I-10 or down from 281. They’ve been burned before by animals that look good on paper but fall apart in the field. That’s not what happens here.
When you buy a live animal from us, you’re getting more than just genetics. You’re getting an animal raised with care, handled with respect, and backed by a operation that’s been doing this for years. We’ve sold to breeders in the San Antonio area who’ve used our cattle to transform their entire herd’s performance. One rancher near Helotes told us our donor cow line single-handedly improved his calf crop within two seasons. That’s the kind of result we’re after.
We keep things straightforward. You tell us what you need — whether it’s a proven bull, a young heifer prospect, or a horse with specific bloodlines — and we’ll help you find the right match. No pressure. No games. Just good livestock and honest advice.
San Antonio Events & Activities at Casaray
2026 Bluebonnet Kick-Off Classic July 28 to August 1, 2026
2026 International Brahman Cattle Selection & Judging Course
Texas Hosts Cattle Selection and Judging Course
Just days before the world-renowned Houston Livestock Show and Rodeo, Texas became the global epicenter for Brahman cattle excellence with the Bilingual Brahman Cattle Selection and Judging Course, held February 28 and March 1.
The program took place in Groveton at Rancho Casaray, and on its second day in Hungerford at Heritage Cattle Co., two leading operations that reflect the strength, tradition, and genetic influence of the Brahman breed in its place of origin.
The event, organized by Brahman Friends and FLG Agrisolutions, brought together participants from across the Americas for an intensive, hands-on educational experience focused on evaluation, functional selection, and the future of Brahman cattle in the global beef industry
A highlight of the course was the participation of prominent American cattlemen and educators, including renowned judge and breeder Judd Cullers, who hosted the day at Heritage Cattle Co., and Dr. Joe Paschal, one of the most respected academic voices in cattle evaluation and selection.
At Casaray Ranch, the program is led by Dr. César Castro, a Venezuelan veterinarian and international Brahman breeder whose program has produced national
and international champions in the United States. His farm in Groveton has become a benchmark for progressive Brahman genetics and a bridge between North and Latin America.
The international panel also included prominent Colombian cattle professionals Julio Gutiérrez, Fernanda Linares, and Jorge Silva, whose experience in tropical production systems provides a valuable practical perspective on breed selection and functional efficiency.
This unique educational initiative highlights the importance of combining the knowledge of cattle professionals from tropical countries where Brahman plays a fundamental role in beef production with the genetic, technical, and historical foundation developed in Texas, the birthplace of the American Brahman.
Today, Brahman cattle are present in numerous countries worldwide, and it is from Texas that this genetic progress continues to expand, influencing herds and improving productivity in diverse environments.
By connecting leading U.S. operations with experienced cattlemen from tropical regions, the course strengthens international collaboration, accelerates genetic advancement, and solidifies Texas as the epicenter of Brahman innovation and the global development of the breed.
For breeders in San Antonio, events like this aren’t just news — they’re opportunities. If you’re serious about Red Brahman genetics, you want to be connected to a program that’s shaping the breed’s future. That’s what we’re doing right here. And it’s accessible to anyone in the San Antonio area willing to make the short trip out to Groveton to see what excellence looks like up close.

Protecting Bloodlines. Building the Future in San Antonio.
At Casaray Ranch, breeding is more than production — it is a long-term commitment to preserving the strength, health, consistency, and value of future generations. Every donor cow, sire, embryo, and horse represents years of planning, selection, and responsible breeding decisions focused on building livestock programs that stand the test of time. San Antonio breeders know the drill: Brangus and Angus have their place, but Red Brahman genetics from Casaray bring hardiness and heat tolerance that thrive in Bexar County’s hot summers.
