1a.Objectives (from AD-416):
Facilitate research in forage management and livestock production at the Grazinglands Research Laboratory, El Reno, OK including cooperative research between OAES and ARS.
1b.Approach (from AD-416):
OAES and ARS will collaboratively maintain experimental herds of cattle and flocks of sheep at the Grazinglands Research Laboratory, sufficient in number and kind to meet research objectives in the areas of forage and livestock production, impacts of agriculture on the environment, and conservation of natural resources.
The Oklahoma Agricultural Experiment Station maintained a herd of about 300 cows and 200 ewes during the year for use by location scientists. A graduate student project focused on how nutrition of a pregnant cow influences the carcass merit of her calf is being supervised collaboratively by faculty at Oklahoma State University and scientists at the Grazinglands Research Lab. The herd genetics has undergone significant modification as we transitioned to a new five-year plan. The OSU regents have released the livestock inventory to ARS and OSU will no longer maintain livestock for the location. However, collaboration will continue under a new NFCA on mutually beneficial research problems for the Southern Great Plains.
