In an ongoing series of studies, researchers at Texas A&M and West Texas A&M have presented a convincing case that shipping and receiving stress cause calves to lose the “antioxidant” vitamins E and A. Antioxidants have also been shown to be important components of a healthy immune system in human medicine.
A weaning practice that has received increased attention both in terms of research and producer experience is fenceline weaning. It’s a simple process: calves and cows are separated but can still go nose-to-nose and see, hear and smell one another.
Research suggests some non-traditional approaches can help reduce weaning stress. Studies at University of California at Davis compared weaning seven-month old calves by one of five methods:
Research continues to draw the connection between mineral status and immune-system response to keep feeder calves healthy and growing. Now, three recent trials on over 1,000 calves demonstrate that connection in the field.
