Forages and Grazing

Feed is the greatest expense in raising livestock and often accounts for more than 50 percent of the total cost of production on a cow-calf operation. In 2005, Cattle-Fax reported total annual cow costs in the northwest United States were $379 per head. These costs have increased each of the past several years due largely to rising feed prices.

All animals need adequate nutrients, including energy, protein, minerals, vitamins, and water. Their needs vary depending on species, age, stage of production and environmental conditions.

Forages are the foundation for Idaho's ruminant livestock enterprises and provide rotational crops for sustainable production of cereals and row crops. In the future they may be a source for liquid fuels generation.  More information

corn fieldVariety Testing
Many varieties of alfalfa and corn are available to U.S. producers.  The data from these trials can be combined with industry data to help producers choose the best varieties for their growing conditions and management objectives.  More information
