The progression from gestation into lactation represents the transition period, and it is
accompanied by marked physiological, metabolic, and inflammatory adjustments. The entire …

Simple Summary Modern dairy cows have elevated internal heat loads caused by high milk
production, and the effects of accumulating incremental heat are exacerbated when …

The objectives were to characterize the prevalence of periparturient diseases and their
effects on reproductive performance of dairy cows in seasonal grazing farms. A total of 957 …

Dairy cows suffer blood Ca losses as lactation begins and might be affected by
hypocalcemia in its clinical (total serum Ca concentration< 1.50 mM) or subclinical form …

Our aim in this Journal of Dairy Science centennial review is to describe the evolution of
focus on metabolic indicators, from discovery and description to evaluation at the individual …

Total blood calcium (Ca) concentration in the adult cow is maintained between 8.5 and 10.0
mg/dL (2.1 and 2.5 mmol/L). Nearly all cows will experience some degree of hypocalcemia …

The transition period is the most critical phase in the life of high yielding dairy cows. Within a
few weeks, cows are submitted to many challenges (physiological, nutritional, psychological …

In the last decade, several new aspects of the inflammation of the bovine endometrium have
been investigated and described, including a new definition of subclinical endometritis. This …

The objectives were to study the effects of induced subclinical hypocalcemia [SCH, blood
ionized Ca (iCa 2+)< 1.0 mM, without recumbency] on physiological responses and function …

Our objectives were to evaluate the association of subclinical hypocalcemia (SCH)
dynamics with the risk of early lactation disease, removal, and milk production. We …
