Other ways to enhance the
efficacy of existing
drenches
Goats metabolise drenches faster
than sheep and cattle
probably means the same dose rates
are not equally effective in all
ruminants
BZs (white drenches)
reduce feed by at least 50% 24
hours before drenching and for 24
hours after drenching BZs bind
to rumen particulate matter and
this will slow rumen emptying
and hence slow the uptake into
the blood stream so it will last
longer and be more effective
repeat dosing at 12-24 hour
period concentration of BZ in
blood similar to that of sheep
