This experiment was designed to collect data in regard to the optimum
level of alfalfa hay feeding for calves wintered on bluestem pasture. One
group of heifers was fed twice as much alfalfa hay as another, but the
supplemental total digestible nutrient intake was maintained at about
the same level by feeding grain to heifers on the lower level of alfalfa hay.
Two previous tests are reported in Circulars 349 and 358.
