Planning for Resilience: Using Scenarios to Address Potential Impacts of Climate Change for the Northern Plains Beef System

Proceedings Home W2W Home w2w17 logo

Purpose

Resiliency to weather extremes is a topic that Northern Plains farmers and ranchers are already familiar with, but now climate change is adding new uncertainties that make it difficult to know the best practices for the future. Scenario planning is a method of needs assessment that will allow Extension and beef system stakeholders to come together using the latest climate science to discover robust management options, highlight key uncertainties, prioritize Extension programming needs, and provide an open forum for discussion for this sometimes controversial topic.…

Evaluation of a Model to Predict Enteric Methane Production from Feedlot Cattle


Proceedings Home W2W Home w2w17 logo

Purpose

Continual refinement of methods estimating enteric methane production in beef finishing cattle provides a more accurate assessment of the environmental impact of the beef industry.  The USDA-OCE publication “Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory” identified conservation practices and management strategies for reducing greenhouse gas emissions while improving agriculture production (Eve et al., 2014). …

Methods for Regulating Dry Matter Intake in Grazing Horses


Proceedings Home W2W Home w2w17 logo

Purpose 

Pasture dry matter intake of many horses (e.g., mature idle horses) exceeds that necessary to provide daily energy requirements creating an inefficiency. One strategy for regulating pasture intake is to restrict the herbage mass (HM) available for grazing by “pre-grazing” with horses having higher nutrient requirements (e.g., work, growth, lactation), or an entirely different species (e.g., cattle, sheep or goats) using a “leader-follower” rotational grazing system.…

A Quantitative Assessment of Beneficial Management Practices to Reduce Carbon and Reactive Nitrogen Footprints of Dairy Farms in the Great Lakes Region

w2w17 LogoProceedings Home | W2W Home 

Purpose 

Assessing and improving the sustainability of dairy production is essential to secure future food production. Implementation of Beneficial Management Practices (BMPs) can reduce carbon and reactive nitrogen footprints of dairy farms. BMPs can and have been developed for different farm components, including feed, manure management and field cultivation practices.…

Intake and Digestibility of Nutrients, Manure Production, and Nitrogen Excretion as Affected by Nonfiber Carbohydrate Sources and Rumen Degradable Protein Levels in the Diet of Dairy Cows


Proceedings Home W2W Home w2w17 logo

Purpose           

This study was to determine the effects of nonfiber carbohydrate (NFC) sources and rumen degradable protein (RDP) levels in diet on apparent total-tract nutrient digestibility, manure production and nitrogen (N) excretion in dairy cows.…

Transferring Knowledge of Dairy Sustainability Issues Through a Multi-layered Interactive “Virtual Farm” Website

Proceedings Home W2W Home w2w17 logo

Purpose

The goal of the Sustainable Dairy “Virtual Farm” website is to disseminate research-based information to diverse audiences from one platform. This is done with layers of information starting with the mSustainable dairy logoost basic then drilling down to peer-reviewed publications, data from life-cycle assessment studies and models related to the topics.…
