Livestock Rumen & Greenhouse Gases

Livestock Rumen & Greenhouse Gases

LEARN: how farms can help reduce greenhouse gases (GHG) in livestock systems-- with a focus on the methane (CH4) produced in the livestock gut where microbes live and help animals digest feed.

(enteric fermentation, comparison of emissions between stall vs grazing livestock).

9am: The Magical Mystical Rumen and Dairy Cattle Sustainability presented by Dr. Larry Chase (Cornell)

Dairy cows are a biological factory that can convert a wide variety of forages and feeds into milk which is a high-quality food for humans. The key to this ability is the function of the rumen microorganisms. Many of the feeds used by the dairy cow are co-products of food processing and are not directly consumable by humans. The progress that dairy industry has made in lowering its impact on the environment and improving sustainability will be highlighted.

10am: Comparison of Confinement Vs Grazing Dairy Systems: Effect on production performance, nutrient use efficiency, and enteric methane emissions in dairy cows presented by Dr. Andre Brito (UNH)

Grazing systems perform multiple ecosystem services including food production, climate regulation, nutrient cycling, and erosion control. Consumers often associate grazing with “healthier and happy cows” and are willing to pay premiums for “grass-fed” dairy products. However, milk production and nutrient utilization generally decrease in pasture-based systems relative to confinement systems, which may reduce farm profitability depending on milk prices. It should be noted that there is limited research reporting both milk nitrogen (N) efficiency and methane emissions in confined versus grazing dairy cows. Therefore, our overarching objective was to build data sets to compare nutrient utilization in dairy cows under confinement or grazing management where milk N efficiency or methane emissions or both were reported in the same studies. Dietary strategies to mitigate methane emissions in grazing dairy systems will be also explored.

Automated message: Thanks for sharing this event! If you can, please remember to update this listing after your event with a link to the recording. You can do that by coming back to your event here in Connect Extension, clicking "Manage Event" and then "Edit Event." From there, I suggest adding the words "Recording Available Here" to the top of your event and linking out to the recording. Example: Recording Available Here

Thanks for helping us make this an awesome archive of resources for Cooperative Extension!

FAQs for Learn Calendar Users:

Will a recording be available?

That is entirely up to the host of this webinar/online event. If this is an Extension Foundation hosted event - we will update this calendar listing with a link to the recording usually within 48 hours. Keep in mind, many of the offerings found here in Connect Extension are brought to you by your colleagues across the system. While we encourage them to update their listings with recordings, it is entirely up to them.

How do I know if it is an Extension-hosted event?

Extension Foundation posts publicly our events to two calendars - the Extension Foundation Member Calendar and the Opportunities for Cooperative Extension Calendar.  All other events coming from across Cooperative Extension are posted to the Learn Calendar or to one of the regional calendars. All calendars populate to the same main calendar on Connect Extension. To tell the difference between what events are posted to what calendars easily, you'll see the name of the calendar posted above the title of the event if you scroll to the top.

What if I have trouble accessing this webinar?

Please contact the author of this calendar event. The individual that posted this event will have their username automatically listed at the bottom of the body of their post, right above the social media buttons. When you hover over that name, you are able to send them a private message.

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives.
