Effect of Pluronic-F68 fog solution on performance and morbidity of newly received heifer calves.

Morbidity and mortality from bovine respiratory disease (BRD) of newly received feedlot cattle continue to be problems for the feedlot industry. The objective of this study was to evaluate the effects of utilizing a novel breathing treatment containing a nonionic surfactant (Pluronic-F68) on performance and morbidity of high-risk calves during a 45-d receiving period. Angus/Angus-cross heifer calves ( = 240) were acquired in Delhi, LA, and transported (14 h) to the research facility.
