Parturient Paresis. I. the Incidence of Parturient Paresis and Changes in the Total Blood Serum Calcium at Parturition in Prepartum Milked Cows

Abstract

Forty-six cows were prepartum milked from 2 to 16 days. Nine of these cows had parturient paresis. Prepartum milking did not significantly reduce the incidence of parturient paresis. It would seem from the results of this study that factors in addition to the initiation of milk secretion are involved in causing parturient paresis. The incidence of parturient paresis is not seasonal in this herd. © 1947, American Dairy Science Association. All rights reserved.
