| Summary: | Bovine gastrointestinal helminthic refugia is constituted by
eggs and larvae in pastures, so they escape exposure to
anthelmintic treatment and constitute a reservoir of
susceptibility genes to these drugs. Therefore, if treatment is
applied when there is little or no refugia, selection pressure for
anthelmintic resistance increases. This study aimed to compare
the productive performance of cattle reared on winter crops
with and without refugia, applying delayed and pre-entering
anthelmintic treatment, respectively. |
