Titre : IMPROVING RUMINANT USE OF FORAGES IN SUSTAINABLE PRODUCTION SYSTEMS FOR THE WESTERN U.S.

Identification : ARZT-1370160-R50-109

Pays : Etats Unis

Durée : Oct 1, 2012 à Sep 30, 2014

Domaine : Management of Range Resources ; Desert and semidesert shrub land and shinnery ; Beef cattle, live animal ;

Partenaire : UNIVERSITY OF ARIZONA 888 N EUCLID AVE TUCSON,AZ

Objectif
Identify the shortcoming of the 1996/2000 Beef NRC for cows grazing in Western rangeland environments. Disseminate and translate research-based management strategies to stakeholders for improving ruminant use in sustainable forage production systems. Provide professional development and mentoring opportunities for committee participants, young scientists, stakeholders, and graduate students

Descriptif
We will be evaluating voluntary forage intake of cows and relating it to cow longevity. The first study will involve evaluating voluntary forage intake of older cows (over 8 years old) that have survived the range conditions at the V - V ranch. This intake will be compared to the Beef NRC which gives good estimated of average values for cows. The second study will involve evaluating residual feed intake (RFI) of heifers. We will later evaluate their forage intake and longevity. This could lead to SNP panels being developed to help producers in their selection decisions. We will document the economic value of the panels. The results will be analyzed and presented at extension meetings and published in appropriate journals.
