The way that animals are fed and managed before going into the
feed lot may influence the rate and efficiency of gain on a fattening
ration. This is particularly true with pigs. This experiment was planned
to obtain information on the response of heifers on a fattening ration
after having received different kinds of roughage in their wintering
rations. The different rations were supplemented to make them similar
in protein, total digestible nutrients, vitamins, and minerals.
