The incumbent will be part of a team of USDA-ARS, university, and industry collaborators who are examining the value of alfalfa in dairy cow rations. Specific research objectives for the incumbent include:
1) Evaluate the inclusion of alfalfa in the diets of high-producing dairy cows on performance, nutrient digestibility, and environmental impact.
2) Evaluate the impact alfalfa quality in the diets of high-producing lactating cows on production, nutrient digestibility, and nutrient excretion to the environment.
3) Compare these in vivo results with estimates of results predicted by in vitro laboratory analyses to better define forage quality.
