213 = Diets were formulated to meet the net energy and crude protein requirements of 220 d of gestation.
Control BW, kg = the body weight (kg) of the control cow in each body weight pair used to calculate maintenance and gestation requirements (NASEM, 2016).
NEm provided, Mcal/d = net energy for maintenance provided to each pair that was adjusted weekly (Mcal/d).
CP provided, g/d = crude protein provided to each pair that was adjusted weekly (g/d).
