Abstract

The Land O'Lakes (LOL) Research facility located in Webster City, IA receives 255-260 Holstein bull calves every 2 months from a contract buyer in Wisconsin. The majority of the calves are 4 to 8 days old at arrival. The facility started operations in 197 4, and LOL has conducted nutritional studies on over 50,000 calves since it opened. During the past 15 years, Mycoplasma bovis has reduced both the value and number of saleable calves, primarily because of otitis media and bovine respiratory disease (BRD). A study was initiated to determine milk replacer and calf starter intake, weight gain, feed efficiency, treatment costs, and performance of calves treated for BRD with either Resflor Gold or Baytril, compared with those for calves that were not treated for BRD.
