With rising demand and shrinking beef supply, consumers may facehigher prices at the meat case.
How will you provide the product consumers How will you provide the product consumers desire at a price they are willing to pay? desire at a price they are willing to pay?

Traditional Production
At any given time, about 15-20% of all beef cattle in the US are housed in feedlots. They account for about 10% of all corn use in the US.
80-85% of the life cycle of traditionally-raised beef cattle in the US depends on grass and forages as the sole nutritional source.
Source: 2008 http://snipurl.com/methanecartoon, Last accessed May 7, 2010
If you do the calculations based on the YAN prediction equation and account for the time, manure production, and total meat production from 20% forage to 100% forage in the diet, the methane production increases by
500%
Per pound of beef produced.
Canadian, US, and Australian studies have confirmed these results.
The bigger picture is more than methane.

Grass Fed Beef is an important part of the Grass Fed Beef is an important part of the Beef industry because:Beef industry because:
1.It engages customers that may not eat any other beef.2.It meets the criteria for customers that desire information about how their food is produced3.It meets the needs of customers that do not wish to have animals confined.4.It is usually produced and marketed locally so customers are face-to-face with farmers.5.It is an important lifestyle for many farmers.
