EFFECTS OF REDUCING DIETARY CATION-ANION BALANCE FOR PREPARTUM DAIRY COWS WITH SPECIFIC REFERENCE TO HYPOCALCEMIC PARTURIENT PARESIS

A Dairy Herd Case Investigation with Very Low Dietary Cation–Anion Difference in Prepartum Dairy Cows

During the periparturient period, subclinical hypocalcemia (total plasma Ca concentration <2.0 mmol/l) is a potential problem for the dairy cow; consequently, its prevention is essential for success of fertility and productive performance. Dietary cation-anion difference (DCAD) has been defined as the difference in milliequivalents of cations (Na, K) and anions (Cl, S) per kilogram of dry matte...

Enfluence of increasing dietary cation-anion balance on the performance of lactating dairy cattle

Effects of dietary cation-anion difference on milk fever, subclinical hypocal- cemia and negative energy balance in transition dairy cows

Objective of this study was to determine the effects of varying dietary cation-anion differences (DCAD) in prepartum period on milk fever, subclinical hypocalcemia and negative energy balance in dairy cows of Urmia, Iran. Ninety nine Holstein cows assigned to three groups (n=33) were fed diets with DCAD of -24 (anionic), +80 (cationic) and +230 (cationic) mEq/Kg dry matter for 3 weeks before ex...

effect of dietary cation-anion difference on acid- base balance, calcium homeostasis and performance of holstein dairy cows

this study was conducted on 24 holstein cows in close-up period, in a split-plot in time design, with a 2×2 factoriel arrangement and in a completely randomized framework to evaluate the effect of pre and postpartum dietary cation-anion differences (dcad) on homeostasis of calcium, acid-base balance and the subsequent lactation performance. the first factor was prepartum dcad for which the anim...
