Producers who still select by looks risk investing heavily in low-potential heifers while leaving real profit on the table. The text explains how genomic testing enables early economic sorting, supports smarter beef-on-dairy strategies, and aligns breeding decisions with long-term financial performance. It also warns about rising inbreeding levels and heat stress…
