Transporting heifers creates stress, which in turn causes animals to eat less following transport, notes Susan Eicher, a scientist with USDA's Livestock Behavior Research Unit in West Lafayette, Ind. To help heifers two months and older resume eating after transport, give them access to feed after arrival. However, wait 30 minutes before you offer water. If offered water first, animals tend to fill up on the water, and consequently, eat less.
