A LONGITUDINAL STUDY OF BULK MILK SEROPOSITIVITY TO FASCIOLA HEPATICA IN A SUBSET OF IRISH DAIRY HERDS
Determination of the prevalence of Ostertagia ostertagi, Fasciola hepatica and Dictyocaulus viviparus in Irish dairy herds using bulk milk analysis and examination of the impact of these parasites on the productivity of those herds.
Monthly average S/P ratios across all study herds
Dosing required earlier than dry period
Monthly S/P ratios across ‘Dry’ study farms
Monthly S/P ratios across ‘Wet’ study farms
Only 2 active ingredients remain on the market
Albendazole (Liver Fluke only)
Oxyclozanide (Liver and Rumen Fluke)
Will require minimum of 2 doses
Third Dose probably required
Current efficacy of these products unknown
Need to promote the impact that illegal use (accidental or otherwise) could have on international markets
Some farmers currently willing to take the riskBAN ON FLUKICIDES
