Prepartum Negative DCAD Diets – They’re Not Just for Milk Fever Anymore
نویسنده
چکیده
Hypocalcemia is presented in two forms, the less common clinical disease called milk fever and the more common form called subclinical hypocalcemia (SCH). Depending upon how it is defined and the frequency of blood sampling for diagnosis, SCH can affect 25 to 40% of primiparous and 45 to 80% of the multiparous cows. Cows with SCH have reduced dry matter (DM) intake, suppressed measures of innate and acquired immune function, compromised energy metabolism, and increased incidence of other periparturient diseases. This is why hypocalcemia is considered a “gateway” disease for dairy cattle.

Effect of Pre-partum Dietary Cation-anion Difference on the Performance of Transition Sahiwal Cattle
Dietary cation anion difference (DCAD) is an important aspect of dairy nutrition, especially in the transition period. Sahiwal cattle is the highest milk producing breed among Zebu cattle. We planned first study on transition Sahiwal cattle to determine the effects of feeding varying levels of negative DCAD. For this purpose, twenty pregnant cows (at the 250th day of gestation) were selected an...

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...

Twenty four periparturient cows were used to determine the effects of DCAD on acid-base balance, plasma and urine mineral concentrations, health status, and subsequent lactation performance. Each group of 12 cows received either a diet containing -100 DCAD or +100 DCAD for 21 d prepartum. Both anionic and cationic groups were divided into two groups, one received a +200 DCAD and the other +400 ...
متن کاملDCAD: It’s Not Just for Dry Cows
For more than 20 years, dairy producers have been using low DCAD diets in their dry cow feeding programs to prevent milk fever and subclinical hypocalcemia during the transition period. The use of low DCAD diets in dry cows has virtually eliminated the incidence of milk fever in most dairy herds. While dairy producers are well aware of the importance of proper DCAD concentrations in the dry per...
متن کاملDiet-induced pseudohypoparathyroidism: A hypocalcemia and milk fever risk factor.
Subclinical hypocalcemia may affect half of all multiparous cows, and clinical hypocalcemia or milk fever affects approximately 5% of dairy cows each year. This disorder of calcium homeostasis can be induced by several dietary factors. Recent studies implicate high dietary potassium and high dietary cation-anion difference (DCAD) with increased risk of milk fever. The hypothesis tested in this ...
