Ruminant-based food production faces currently multiple challenges such as environmental
emissions, climate change and accelerating food–feed–fuel competition for arable land …

Because animal agriculture has been identified as a major source of nonpoint N pollution,
ways to reduce the excretion of N by production animals must be examined. The objective of …

This experiment was conducted to evaluate different microalgae species as protein
supplements in the nutrition of lactating dairy cows in comparison to soya bean meal. Four …

The objective of this study was to evaluate the effects of supplementing a metabolizable
protein (MP)-deficient diet with rumen-protected (RP) Met, Lys, and His, individually or …

Providing essential amounts of balanced nutrients is one of the most vital aspects of
livestock production. Among nutrients, protein has an essential role in many physiological …

Eighty-four Holstein cows were assigned to a randomized block experiment to determine
effects of supplementing pre-and postpartum diets containing highLys protein supplements …

A meta-analysis of published studies was used to investigate the effect of rumen-protected
methionine (RPM) added to the diets of lactating dairy cattle on dry matter intake, milk …

The objectives of our study were to evaluate the productive response to methionine
supplementation in lactating dairy cows and to define a relationship between metabolizable …

Most prediction schemes of milk protein secretion overestimate milk protein yield from dairy
cows at high protein intakes, thereby overestimating milk protein yield response to protein …

The effect of the content of lysine and methionine in metabolizable protein (MP) on lactation
performance and N utilization in Chinese Holstein cows was determined. A control diet (C) …
