Abstract :The effects of an anionic versus cationic insert ignore into journalissuearticles values(control); diet on plasma mineral levels and health status were investigated in 24 dry pregnant Holstein-Friesian cows during the last 3 weeks of pregnancy. The cows were in their third or fourth parity, had a moderate level of milk production in their previous lactation, and did not have a history of milk fever. The anionic diet significantly improved plasma calcium status, as compared to the control insert ignore into journalissuearticles values(2.18 vs. 1.99 mmol L-1); and nonsignificantly reduced the incidence of subclinical hypocalcemia insert ignore into journalissuearticles values(1/12 vs. 5/12); without affecting other periparturient diseases. Other plasma mineral levels were unaffected, except chloride, which was higher in the anionic group. The results show that an anionic diet could improve calcium status around the time of parturition and reduce the incidence of subclinical hypocalcemia when fed to moderate producing dairy cows not predisposed to milk fever.
