TL;DR: DRAX is a more efficacious and cost-effective metaphylactic antimicrobial than MIC or TET in feedlot calves at ultra-high risk of developing UF and two methods of calculating feedlot performance variables are presented.

An evaluation of the relative efficacy of tulathromycin for the treatment of undifferentiated fever in feedlot calves in Nebraska.
O. C. Schunicht,Calvin W. Booker,P. Timothy Guichon,G. Kee Jim,B. K. Wildman,T. J. Pittman,T. Perrett +6 more
TL;DR: In the economic analysis, the benefits observed resulted in an economic advantage of $52.50 USD/animal in the TULA group due to lower first UF relapse and overall mortality rates, even though the occurrence of yield grade USDA-4 carcasses increased and the initial UF treatment cost was higher.

•Journal Article
A comparison of 2 vaccination programs in feedlot calves at ultra-high risk of developing undifferentiated fever/bovine respiratory disease
B. K. Wildman,T. Perrett,Sameeh M. Abutarbush,P T Guichon,T. J. Pittman,Calvin W. Booker,O. C. Schunicht,Fenton Rk,Jim Gk +8 more
TL;DR: It is demonstrated that it is more cost effective to use an MLV3-BT2 vaccination program than a MLV4-BT1 vaccination program in feedlot calves at ultra-high risk of developing UF/BRD.

The effect of bovine viral diarrhea virus infections on health and performance of feedlot cattle.
Calvin W. Booker,Sameeh M. Abutarbush,Paul S. Morley,P. Timothy Guichon,B. K. Wildman,G. Kee Jim,O. C. Schunicht,T. J. Pittman,T. Perrett,John A. Ellis,Greg D. Appleyard,Deborah M. Haines +11 more
TL;DR: Although type-I BVDV infections in feedlots appear to contribute to higher mortality rates, the presence of PI calves alone does not appear to have a strong impact on pen-level animal health and feedlot performance.
