Start Date: Sep 15, 2007
End Date: Sep 14, 2012
Improved germplasm from ongoing ARS programs and breeding populations under investigation will be established in small and large scale research plots. Large scale plots will be used to determine animal performance, carrying capacity and species preference based on weight gain and time spent grazing each species. Small plots will be grazed to determine animal preference among plant genotypes and relative persistence among plant genotypes under heavy grazing. Livestock preference, dry matter production and plant persistence under grazing will be utilized in plant improvement programs.
