Exploring the Nexus of Livestock Genetics

Breaking Boundaries: USLGE Ventures Beyond Borders

In February 2024, Monterrey, Nuevo León, Mexico, witnessed a historic moment in the livestock industry as the United States Livestock Genetics Export (USLGE) held its annual meeting outside the United States for the first time since its inception in 1994. The event, attended by approximately 70 participants, marked a significant milestone in international collaboration within the livestock genetics sphere.

USLGE, a nonprofit trade association representing various sectors of the U.S. livestock industry, serves as a pivotal bridge connecting international producers with superior genetic resources in the United States. With its diverse membership encompassing dairy, beef, swine, horse, small ruminant breeding industries, and embryo and semen sectors, USLGE stands as a beacon of expertise and collaboration in genetic selection and trade.

Unveiling Excellence: A Journey Through Rancho San Juan


The annual meeting provided a platform for participants to engage in insightful discussions, exchange knowledge, and forge meaningful partnerships. Notably, the event witnessed a record attendance of in-person representatives from the United States Department of Agriculture Foreign Agricultural Service (USDA-FAS), underscoring the commitment to fostering international cooperation in livestock genetics.

A highlight of the gathering was the opportunity to visit Rancho San Juan in Pesqueria, Nuevo León, Mexico, graciously hosted by Arnulfo de la Garza Montemayor and supported by David Hobbs of the American-International Charolais Association and the Asociación Charolais Charbray Herd Book de México. Rancho San Juan, a beacon of excellence since its establishment in 1960, has continually raised the bar in livestock genetics, particularly in Charolais and Charbray cattle.

Arnulfo de la Garza Montemayor shared invaluable insights into the ranch’s journey towards genetic enhancement, showcasing the remarkable strides made through the strategic integration of Charolais genetics sourced from various breeders in the United States. This collaborative effort exemplifies the synergy USLGE fosters, where international producers can access a diverse pool of superior genetics to elevate their breeding programs.

Embracing Innovation: Harnessing Technology for Genetic Advancements

Situated in the semi-desert region of northeast Mexico, Rancho San Juan is a testament to dedication and excellence in livestock breeding. With a steadfast commitment to quality and professionalism, the ranch has invested significantly in facilities, technology, and genetic advancements to offer its clientele top-tier Charolais cattle.

The tradition of honesty and integrity ingrained in Rancho San Juan’s ethos is reflected in its continued success, evidenced by numerous accolades and championships in Mexican livestock exhibitions. As a leading center for Charolais and Charbray genetics, the ranch exemplifies the ethos of USLGE — facilitating global access to superior genetics while upholding the highest standards of integrity and excellence.

The USLGE annual meeting in Monterrey, Mexico, served as a testament to the power of collaboration and knowledge sharing in advancing livestock genetics on a global scale. Through initiatives like these, stakeholders across borders can harness the collective expertise and resources to drive innovation and excellence in the livestock industry.

As we reflect on the insights gained and connections forged during this momentous gathering, it is evident that the future of livestock genetics lies in continued collaboration, innovation, and a shared commitment to excellence. Together, we can shape a brighter future for the livestock industry, one superior genetic trait at a time.
