Study shows Hereford heterosis advantage http://www.cattlenetwork.com/cattle-resources/genetics/Heterosis/study-shows-hereford-heterosis-advantage-113924119.html Preliminary research shows a $78 advantage for Hereford-sired calves compared to Angus-sired calves in a real-world commercial setting. Creating a chronic http://www.cattlenetwork.com/cattle-resources/genetics/Heterosis/creating-a-chronic-113986049.html All chronic feedlot animals may not be defined the same.

It's time to capture direct, maternal heterosis http://www.cattlenetwork.com/cattle-resources/genetics/Heterosis/its-time-to-capture-direct-maternal-heterosis-114054794.html Longevity, rebreeding and calf survivability are gaining importance as the nation’s cow herd becomes more straightbred. Animal scientists say that is because commercial cow-calf producers have forgotten or ignored hybrid vigor (heterosis). Cattle Breeds: Crossbreeding “Revisited” http://www.cattlenetwork.com/cattle-resources/genetics/Heterosis/cattle_breeds_crossbreeding_revisited_132082488.html The benefits of crossbreeding systems in the beef sector have been extensively researched over the years, and the practical implications of the benefits of crossbreeding are as relevant and important today as they were 25 years ago. Purchasing versus raising replacement females http://www.cattlenetwork.com/cattle-resources/genetics/Heterosis/Purchasing-versus-raising-replacement-females-136376188.html The recent decline in the national beef cowherd has increased interest in replacement female decisions.
