## Resource

A major breakthrough in cattle genetics has been uncovered: a previously undetected gene variant causing hornlessness in Brahmans, now added to commercial DNA tests. For years, producers struggled with hornless cows testing as having horns — a mystery solved by researchers at the University of Queensland. With four known hornless variants and tests only checking for two, this new variant, originating in Brazil, finally closes the gap. The demand for naturally polled cattle is soaring — safer, cheaper, and easier to manage, especially in tropical conditions. Now, breeders can trust their genetic results, boosting confidence and herd efficiency. But a new question emerges: how did this gene make its way into Australian herds? The updated testing is already available, poised to transform breeding practices nationwide. Support the show: Get a discount at https://solipillow.com/discount/dnn.
