Effect of crude protein levels and metaphylaxis on health, growth, and performance of newly received stocker calves and subsequent feedlot and carcass performance

<p>The objectives of this study were to evaluate the effects of: (1) metaphylactic antibiotic administration (none or Excede on arrival); and (2) receiving diet crude protein levels (17.1 % or 11.9 % CP) on respiratory disease incidence, mortality, and growth performance of beef calves receive...
