We’re pleased that over half of our first-calf heifers bred to Wagyu bulls have calved in the first thirty days, and relieved that they have instinctually set up nurseries early-on. I’m hoping that last spring’s bumper crop of ground squirrels will keep the coyotes occupied with easier prey, but nonetheless these new mothers seem especially vigilant after calving this year.
Typically a cow or two will stay with a group calves while the other mothers graze to be later relieved of duty after an hour or two. Just how these new mothers communicate and delegate duties is a mystery, but they do. My own unscientific and unproven theory is that the newest mothers whose fresh calves need more constant attention are usually selected to babysit the bunch. After being raised in nurseries, the calves learn the security of the herd and remain quiet and well-behaved until their mothers return. However, back and forth to the water trough in the mornings and early evenings with their mothers, the calves become untrained, running in all directions as they find their legs.
