In light of increasing global protein prices and with the need to reduce environmental impact
of contemporary systems of milk production, the current review seeks to assess the feasibility …

Heat stress (HS) has adverse effects on the body: it decreases body weight, feed efficiency,
feed intake, carcass quality, and nutrient digestibility. Chromium (Cr) can prevent lipid …

The objective of this review was to explore the relationship between lactational performance
and health. We focused on lactational incidence rates (LIR) of the production diseases that …

The efficiency of N utilization in ruminants is typically low (around 25%) and highly variable
(10% to 40%) compared with the higher efficiency of other production animals. The low …

Sixteen Holstein cows in midlactation were randomly assigned to treatments in a replicated
4× 4 Latin square. Two levels of CP (16.1 vs. 18.8%) with or without supplemental …

The objectives of this experiment were to investigate the effects of two ruminally degradable
protein (RDP) levels in diets containing similar ruminally undegradable protein (RUP) and …

The concept of improving animal performance by going beyond simply meeting
requirements and synchronizing ruminal availability of protein and energy has been with us …

Metabolizable protein (MP) supply and amino acid balance were manipulated through
selection of highly digestible rumen-undegradable protein (RUP) sources and methionine …

The review is based on a compiled data set from studies quantifying liver release of glucose
concomitant with uptake of amino acids (AA) and other glucogenic precursors in …

A database reviewing the metabolism of nitrogen (N) compounds from absorption to milk
has been compiled from 14 published and unpublished studies (33 treatments) that …
