Just to be clear, in our location there is only one hay cutting. Very rarely do we get a second cutting, and for sure not this year either.
One cutting all the years that I have had goats, which is only 4 years. 3 out of these we had dry years, and this year spring started late. Maybe we will see a second cutting one day. 😊I'm impressed with your observations, and stalwartness to the cold (1 cutting!! Even in WI we usually get 3) but I don't have much to add. I'd think the carbs would be especially attractive to ruminants in the winter.
