4. Extreme Weather - COLD
Adapted heavy hair coat cattle have a critical temp of 15 degrees F with dry hide
For each degree below, energy required goes up 1%
Cows partially compensate by increasing intake
Provide additional feed (to -10 F) and/or higher quality feeds (> -10 F)
Minimize wind chill with protection
Cows in good condition have some reserve and greater insulation
