Methane Mitigation Strategies for Dairy Herds


Proceedings Home | W2W Home w2w17 logo

Purpose 

The U.S. dairy industry has committed to lowering the carbon footprint of milk production by 25% by 2020. A key factor in meeting this goal is reducing enteric greenhouse gas (GHG) emissions which represent about 51% of the carbon footprint of a gallon of milk. Methane (CH4) is the primary GHG emitted by dairy cows. Total methane emissions represented 10.6% of the total U.S. GHG emissions in 2014. Enteric CH4 emissions were 22.5% of …

Feed Management and Phosphorus Excretion in Dairy Cows

What Is the Connection between Phosphorus and Water Quality?

Holstein Cow

“Phosphorus (P) is an essential element for plant and animal growth and its input has long been recognized as necessary to maintain profitable crop and animal production. Phosphorus inputs can also increase the biological productivity of surface waters by accelerating eutrophication. Eutrophication is the natural aging of lakes or streams brought on by nutrient enrichment. This process can be greatly accelerated by human activities that increase nutrient loading rates to water. …

Snap-Shot Assessments of Nutrient Use on Dairy Farms

Nutrient Use Efficiency

Escalations in feed and fertilizer cost, and ebbing milk prices are motivating many dairy farmers to find new ways to improve nutrient use efficiency (NUE) on their farms. But how can NUE be determined and monitored easily on dairy farms, and what improvement in NUE can be realistically expected? Over the past several years researchers at the U.S. Dairy Forage Research Center and the University of Wisconsin-Madison have been developing and using rapid assessment methods to provide …

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and reduce the excretion of nutrients in manure.

Ethanol Co-Products Impact on Manure Nutrient Management Webcast

The rapidly expanding ethanol industry is producing increasing amounts of corn co-products that will be used in livestock and poultry diets. Inclusion of distillers grains and corn gluten feed in diets alter excretion of nitrogen and phosphorous in manure and therefore impacts nutrient planning. This webcast will explain how feeding ethanol co-products may impact manure nutrient management. The speakers are Joel DeRouchey, Kansas State University who will discuss the impacts for swine and poultry operations. Considerations for beef and dairy …
