These cercariae encyst to metacercariae on grass, which are ingested by the final host during grazing. Under optimal conditions, it takes 6 weeks before an infected snail starts to shed infective cercariae. hepatica is the amphibious snail Galba truncatula. In Europe, the principal intermediate host for F. The infection is transmitted by freshwater snails of the family Lymnaeidae. The liver fluke Fasciola hepatica is a parasite of cattle and sheep with a worldwide distribution.

We conclude that in dairy herds exposed to F. hepatica ELISA result on a milk sample from the previous lactation.

Milk production responses after treatment were poor in meagre animals and clinically relevant higher milk production responses were observed in first-lactation animals and in cows with a high (0.3–0.5 optical density ratio (ODR)), but not a very high (≥0.5 ODR) F.

No effects of anthelmintic treatment were found on the average protein and fat content of the milk. hepatica antibody levels from 3–6 months after treatment onwards, a higher peak production (1.06 kg) and a slightly higher persistence (9%) of the lactation, resulting in a 305-day milk production increase of 303 kg. Closantel treatment resulted in a noticeable decrease of anti- F. hepatica to 1) assess the effect of closantel treatment at dry-off (or 80–42 days before calving in first-calving heifers) on milk production parameters and 2) evaluate if a number of easy-to-use animal parameters is related to the milk production response after treatment.
#LA HAINE COW TRIAL#
Here, we present the results of a blinded, randomized and placebo-controlled trial on 11 dairy herds (402 animals) exposed to F. Effective control in dairy cattle is hampered by the lack of flukicides with a zero-withdrawal time for milk, leaving the dry period as the only time that preventive treatment can be applied. The liver fluke Fasciola hepatica is a parasite of ruminants with a worldwide distribution and an apparent increasing incidence in EU member states.
