Welcome back to Better Beef. Today Kaid Panek and geneticist Dr. Lane Giess, focused on practical cattle genetics, crossbreeding strategy, and the evolving role of data in the beef industry. Giess begins by outlining his background growing up in a South Devon seedstock operation, his long-running involvement with the National Western Stock Show, and his academic path through Kansas State University and Colorado State University. He explains how early exposure to livestock judging, meat judging, and seedstock marketing classes shaped his interest in genetics, structure, and economically relevant traits, eventually leading to graduate work on feet and leg soundness and a PhD project on multi-breed heifer pregnancy within the IGS system. Giess describes how his family’s program transitioned from primarily purebred South Devons to composite bulls designed for commercial cow-calf producers seeking practical heterosis and breed complementarity. He explains why they no longer pull their very best yearling bulls out of contemporary groups for shows, noting that altered management skews performance data and weakens genetic evaluations. Throughout, he emphasizes the production-first philosophy: cattle must look the part, but performance and data are non-negotiable. A major portion of the discussion covers heterosis and crossbreeding. Giess quantifies hybrid vigor in terms of added weaning weight and highlights the often-overlooked maternal benefits in fertility, longevity, calf vigor, and adaptability. He reviews the historical “wrecks” from early continental crossbreeding and how that legacy still shapes producer attitudes. He then explains how three-breed composite systems can deliver maximum heterosis and breed complementarity while simplifying replacement female management. The conversation moves into modern genetic tools, including EPDs, genomically enhanced evaluations, and private versus association-run genetic systems. Giess outlines the economic payoff of DNA testing, the increased accuracy for yearling bulls, and why some large integrated operations are building their own proprietary evaluations. He closes by stressing the importance of selection indexes that weight multiple economically relevant traits, the need to balance phenotype with performance, and the role of improved feed efficiency in both profitability and sustainability.
