Abstract:
Five hundred mixed-breed steer and bull
calves (246 lbs) were divided into two treatment
groups, with one group receiving a new
Pasteurella haemolytica vaccine (Presponse®)
at arrival.
There was no difference between groups in
terms of gain, mortality, or morbidity during
the 32-day receiving study. The Presponse
group required fewer (P<.09) medication days
per animal purchased, resulting in $1.68 less
drug cost per head than the control group.
