^a Standard error of mean
^b Equations from Noblet and Etienne [11]
- Milk production (g) = 2.50 × piglet ADG (g) + 80.2 × initial piglet BW (kg) + 7
- Milk DM (g) = 0.401 × piglet ADG (g) + 12.9 × initial piglet BW (kg) + 19
- Milk energy (kcal) = 2.54 × piglet ADG (g) + 78.7 × initial piglet BW (kg) + 153
^c Equations from Perrin [17]
- Milk energy (cal/100gl) = 9.11 fat(%) + 5.86 protein(%) + 3.95 lactose(%)
