Vaccination with Pyramid 4+Presponse SQ (a 4-way viral modified live vaccine with a Pasteurella haemolytica bacterin-toxoid) tended to reduce the incidence of bovine respiratory disease (P=.2) and reduced retreatment rate (P<.06).BeefMorbidityPerformanceFeeder calvesPyramid™ MLV 4Pyramid™ 4+Presponse® SQConference paper
