DPhillips,

Since the last post, I heard back from the biologist and he stated further that the cows coming into estrus, are affected, as you've said, by hours of light, feed, and also fat layer.......so they have it pretty easy this winter, plenty of forage, and as you can see in the picture, they're in good shape. He also said that there is a cow moose on record, in captivity, that came into estrus in March.

So, many things come into the mix......weather certainly has an influence on some of the things......really interesting.
