Dairy calf research in the preweaned phase has been plentiful in the past few decades. However, there is now much to be learned in the relatively unchartered nutritional territory of the post-weaning phase.
When raising replacement heifers, cost per pound of gain is a far more important metric than daily feed cost, according to Tamilee Nennich, dairy nutritionist and board member for the Dairy Calf and Heifer Association.
Researchers at UC-Davis have developed a handy, easy-to-use diagnostic tool to streamline monitoring of calves for respiratory disease, so they can be detected and cared for early in the disease process.
Data gathered in a recent study by the USDA’s National Animal Health Monitoring System also yields important information regarding colostrum delivery, calf nutrition, ventilation and maternal heat stress.
