❄️Winter changes the math.
A hard cold snap, wind, or mud can push a cow's energy needs well past what she needed in the fall, right as she heads into late gestation. LNAS adjusts for weather and conditions and shows whether your ration keeps pace with her needs, so you can make adjustments before you see it in body condition.
Who it's for
Know where your cow herd stands going into winter and calving.
Thin cows at calving cost you at breed-back and again at weaning. See where your ration stands against your cows' needs going into winter and calving.
