Considerable progress has been made in understanding the protein and amino acid (AA)
nutrition of dairy cows. The chemistry of feed crude protein (CP) appears to be well …

This document analyzes emission of non-carbon dioxide greenhouse gases, an important
segment of the environmental footprint of animal production. It has been developed by a …

Nitrogen is a component of essential nutrients critical for the productivity of ruminants. If
excreted in excess, N is also an important environmental pollutant contributing to acid …

This review analyzes published data on manure management practices used to mitigate
methane (CH4) and nitrous oxide (N2O) emissions from animal operations. Reducing …

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 …

This study examined the effect of 3-nitrooxypropanol (3-NOP), a substance under
investigation, on enteric methane (CH 4) emission, rumen fermentation, lactational …

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 …

Two experiments were conducted with the objective of investigating the effects of rumen-
protected methionine (RPMet) supplementation of metabolizable protein (MP)-deficient or …

This experiment was designed to investigate the relation of high and low methane-yield
phenotypes with body weight (BW), dry matter intake (DMI), lactation performance, enteric …

Previous research suggested that crude protein (CP) from canola meal (CM) was used more
efficiently than CP from solvent soybean meal (SBM) by lactating dairy cows. We tested …
