Abstract

Two studies were conducted to determine the effect of feed additives on the transit shrink of yearling cattle. In Trial I, 146 mixed-breed heifers were offered a mineral mixture containing either Terramycin® or Bovatec®, or without additive while grazing native grass pastures. Shrinkage after 300 miles in transit was lower (P.05). The small shrinkage differences observed in these two trials would not justify changes in the weighing practices of feeder cattle.
