To determine whether feeding a calcium-deficient diet during the prepartum period prevents parturient paresis by activating calcium homeostatic mechanisms in dairy cows.
Compared 12 parturitions of dairy cows fed a calcium-deficient diet for approximately 14 days prepartum to 13 parturitions of control cows.
Formulated a palatable experimental diet containing corn silage, ground shelled corn, dried molasses, urea, and monosodium phosphate, providing 8 g of calcium daily per 450 kg of body weight.
Plasma calcium initially decreased upon introduction of the calcium-deficient diet but returned to normal concentrations within 4 days via homeostatic compensation.
Prepartum dietary calcium restriction successfully prevented parturient paresis across all 12 experimental parturitions.

Implication

Controlled study demonstrates that a prepartum calcium-deficient diet prevents parturient paresis in dairy cows, indicating that early homeostatic sensitization protects against milk fever.
