The peripartum period is characterized by dynamic shifts in metabolic, mineral, and immune
metabolism as the dairy cow adapts to the demands of lactation. Emphasis over the past …

The objective of this experiment was to determine the effects of altering the dietary cation-
anion difference (DCAD) fed for the last 21 or 42 d of gestation on glucose metabolism and …

Background Vitamin D is essential for the reproductive efficiency in animals. There are
indications that 1, 25-vitD influenced the farrowing process and thus can decrease …

Background Milk fever (MF), a metabolic disorder in dairy cows characterized by low blood
calcium concentrations postpartum, is well‐recognized clinically. However, comprehensive …

Objectives of the experiment were to determine the length of exposure to an acidogenic diet
that would elicit changes in acid-base balance, mineral digestion, and response to …

Simple Summary Mineral metabolism is altered with the onset of lactation, and a reduction in
concentrations of calcium (Ca) in blood, particularly when it persists for days, is associated …

The onset of lactation represents a challenge for both mineral homeostasis and energy
metabolism in high-performing dairy cows. It has been shown that subclinical and clinical …

The objectives of the present study were (1) to evaluate the effect of prepartum
cholecalciferol treatment on serum Ca concentration during the first 10 d after calving and …

Abstract Providing tablets of 1, 25-dihydroxyvitamin D 3 (1, 25 (OH) 2 D 3), the biologically
active metabolite of vitamin D 3, in a rumen bolus may be used as prevention for …

Vitamin D is a common nutrient in the diets of dairy cows that does not receive much
attention because it is inexpensive, and it uses little space in the ration. Cows are efficient at …
