At Spinelli Angus Ranch, we are committed to building a productive and balanced herd rooted in elite genetics. The foundation of our program consists of fifteen carefully selected females sourced from some of the most respected operations in the Angus breed — Schaff Angus Valley, Byergo Angus, Square B Ranch & Cattle Company, and Gardiner Angus. By incorporating genetics from these leading programs, we are able to produce cattle that not only excel in EPD profiles but also meet our high standards for phenotype, soundness, and structural integrity.
We utilize a progressive breeding approach that combines Artificial Insemination (AI) with the strategic use of a herd sire to optimize both genetic potential and diversity. Our AI program is centered around top-performing sires in the industry, allowing us to advance each generation with intentionality and performance in mind.
Through careful selection and disciplined breeding, Spinelli Angus Ranch continues to develop cattle that perform in the pasture
