Contents Dairy cow fertility has been declining during since the mid‐80s and this has given
rise to numerous scientific studies in which important parts of the pathogenesis are …

Contents For several decades, researchers worldwide report a decrease in fertility in high‐
yielding dairy cows, most probably based on conflicting metabolic and reproductive needs …

The effects of lactation stage, negative energy balance (NEB), and milk fat depression (MFD)
were estimated on detailed milk fat composition in primiparous Holstein-Friesian cows. One …

We determined the relationships among ketosis, serum metabolites, body condition, and
reproductive disorders and performance in dairy cows. Blood samples from 213 dairy cows …

In the current Dutch protein evaluation system (the DVE/OEB1991 system), two
characteristics are calculated for each feed: true protein digested in the intestine (DVE) and …

There is a need to develop simple ways of quantifying and estimating CH4 production in
cattle. Our aim was to evaluate the relationship between CH4 production and milk fatty acid …

The objective of this study was to obtain information on variation between dairy cows in
muscle and fat tissue mobilization around parturition and to study the association between …

Increasing the availability of glucogenic nutrients relative to lipogenic nutrients has been
hypothesized to decrease the production of milk fat, to improve the energy balance (EB), and …

The aim of this study was to determine the methane (CH 4) mitigation potential of 3-
nitrooxypropanol and the persistency of its effect when fed to dairy cows in early lactation …

Negative energy balance-related metabolic disorders suggest that the balance between
available lipogenic and glucogenic nutrients is important. The objectives of this study were …
