A new Calf Note has been posted at Calf Notes.com.

In Calf Note #171, entitled "Immunity in Jersey calves," author Jim Quigley discusses a common query he gets when he visits with calf raisers, especially those who raise both Jerseys and Holsteins. That question is, “Why do I have more challenges with my Jersey calves?”

What are some of the reasons why Jersey calves seem to differ from Holsteins?

“Some recent research suggests that both nutrition and immunity effects may be involved,” Quigley says.
