Beef Cattle Supplementation

Ryan Reuter, Oklahoma State University

Sustainability in grazing systems is the nexus of simultaneous improvements in profit, social capital, and environmental impact. Our research investigates ways to use supplements to increase food production while reducing enteric methane emissions, and increase profit for ranchers. This seminar will discuss preliminary data from a few experiments to show that, in general, supplementation that improves cattle ADG (profit and food production) dilutes enteric methane emissions per unit of food produced. However, technology to decrease absolute methane emissions while also improving food production and profit remains elusive.

New National Cattle Comfort Advisor

Albert Sutherland, Oklahoma State University

Cattle producers have always monitored their cattle to get a handle on weather’s impact. Now they have a tool that measures cold and heat stress levels. The National Cattle Comfort Advisor lets cattle producers closely monitor difficult weather situations and provides a way to measure severity and length of cold or heat events. This new tool uses four weather variables, air temperature, wind speed, sunlight and humidity, to calculate heat and cold index values. National maps are produced on a hourly basis at three sunlight levels. Past maps go back to January 1, 2016. Al Sutherland will cover some of the National Cattle Comfort Advisor basics and ways it can be used to monitor cold and heat stress extremes and changes.

New Insights into Flash Droughts Across the United States

Jordan Christian, Graduate Research Assistant
School of Meterology, University of Oklahoma

Flash droughts are characterized by the rapid onset and development of drought conditions. These types of droughts can adversely affect vegetation health by quickly depleting root zone soil moisture and increasing moisture stress. Significant yield loss can occur in agricultural regions if flash drought develops during sensitive stages in the growing season.

Webinar participants can expect to learn:
- What defines flash drought
- Hot spots for flash droughts in the United States
- Characteristics of flash droughts

Grazing Cover Crops in Oklahoma

Alex Rocateli, Oklahoma State University

In the long term, summer cover crops may improve soil health when introduced to a wheat-fallow system. However, they add extra costs and may affect the wheat development and yield. Grazing cover crops can be a great approach to recovering costs, and it may not have significant impacts on the cover crops benefits to soil and next wheat crop.  Join us to discuss one-year results of an on-going two-location study which evaluates eight summer cover crops under different simulated grazing regimes and their effects in the next wheat.
Webinar participants can expect to learn:
•    Information about cover crop biomass/forage availability under different simulated grazing regimes from Summer 2016.
•    Summer cover crops effects on the 2017 wheat crop yield.
•    This seminar presents partial data of an on-going study; therefore it will be discussed as a case study

​"Does Climate Change Your Plate?" Consumer Curriculum

Barbara Brown, Oklahoma State University

Many consumers have minimal understanding of where their food comes from, how it is produced and how production, particularly of beef, impacts the environment.

A program, “Does Climate Change Your Plate” was developed to address that and other issues such as the difference between weather and climate, the amount of greenhouse gasses linked to all sources including agriculture, and looking particularly at the contributions from beef production. Topics such as how changing climate may impact a consumer’s pocketbook, nutrition and health concerns associated with beef, how consumers can adapt to higher costs and better food choice options and finally how they, through their food buying and eating choices, can ensure that resources used during production are not wasted are also addressed.

Webinar participants can expect to learn highlights of:

  • The amount of greenhouse gasses EPA shows are the result of livestock production;
  • Potential impacts of climate change on consumer prices for beef and adaptation strategies;
  • Health issues consumers consider when making protein choices; and
  • The consumers’ role in reducing food waste and reducing harmful impacts on the environment.

Forage Supplementation Strategies and Methane Production of Beef Cattle

Andy Cole, Retired USDA-ARS

The nutrient composition of grazed forages frequently does not meet the nutrient requirements of the grazing animals. For example, winter forages are frequently low in protein and digestible energy whereas winter/spring grazed wheat has an excess of protein. In order to optimize use of forages producers frequently provide supplementary protein and/or energy. These generally improve forage utilization, increase carry capacity, and increase animal performance; however, the effects on greenhouse gas emissions are not known.

Webinar participants can expect to learn:

  • effects of protein supplementation to low quality forage diets
  • effects of energy supplementation on high quality wheat forage
