At AU, Foulum, an experiment with two levels of protein and two levels of fat in the diet for heifers aged 6-13 months was conducted. In one diet both dietary protein and dietary fat were relatively low (Miljø), and in the other diet, protein and fat were both relatively high (Praksis). It was the...

Danish dairy cows account for 45% and 56% of the total animal nitrogen (N) excretion and enteric methane (CH₄) production, respectively. Authorities and the dairy cattle industry aim to reduce the negative impact of dairy cows on the environment, particularly regarding N and CH₄ emissions. The...

This article describes the progress of improved breeding and selection of dairy cows for improved immunity, heat tolerance, disease resistance, feed efficiency, methane production, reproduction and mastitis traits, as well as improvements in dairy farming and husbandry practices, which will result...

The EU 2030 climate target requires a considerable reduction in greenhouse gas emissions from society, including the non-ETS sector that also encompass agriculture. The report provides an overview of potential and effects of measures for reducing agricultural greenhouse gas emissions in Denmark....

The purpose of this analysis is to consider the regulation of ammonia emissions from livestock farms, especially in relation to Natura 2000 areas in the Netherlands, Germany (Schleswig-Holstein) and Denmark. This analysis includes both an assessment of the nature, the legal framework and the...

This report presents the findings of a cost-effectiveness analysis of greenhouse gas (GHG) reduction measures in Danish agriculture. Seven GHG mitigation measures (with their corresponding expected implementation potential) are included in the assessment: (1) biogas production from livestock...

The purpose of this study is to identify greenhouse gas (GHG) mitigation measures related to agriculture which can deliver cost-effective contributions to the targeted reduction in GHG emissions in Denmark. A total of 21 GHG mitigation measures are included in the assessment. The stipulated...

Ammonia emission is a significant source of air pollution, especially in areas with a high density of livestock, since the largest part of ammonia emission occurs as a consequence of animal production. Denmark has agreed that by 2010, it will have reduced its emission of ammonia by 43%, relative to ...

Since the mid-1980s when government attention focused on the contribution of farm animals to the undesirable levels of nitrogen and methane (from urine and manure) in the environment, attention has been paid to monitoring and reducing these levels and also those of other substances, such as...
