Fluke

Liver Fluke- know the facts!

Liver FlukeLiver fluke, Fasciola hepatica, is a highly pathogenic parasite which causes severe liver damage, especially in sheep, and can result in the sudden death of previously healthy animals. Millions of pounds are lost every year by livestock producers due to liver fluke with the cost of disease per affected animal noted as £6 per lamb and £90 per calf.1

Fluke life cycle
All three stages of liver fluke damage the liver and can cause clinical disease and production losses. The lifecycle of the fluke has a portion outside of the animal and involves a mud snail which thrives in wetter areas.

It is therefore unsurprising after the prolonged above average weather experienced this summer that current guidance from the NADIS August parasite forecast predicts moderate risk in the north and west of Scotland, and low risk in all other regions. However, this doesn’t mean that there will be no, or limited, fl uke across the country in autumn, so it is important to still remain vigilant.

Consider local factors

Control programmes should always take into account the farm history, topography, geographical location and the prevailing weather. Even in years where disease challenge may be lower than normal, vigilance is still important, and special consideration should be placed on fixing any leaky water troughs, fencing off wet or boggy areas in fields and maintaining effective drainage to reduce snail habitats.

The four elements of sustainable liver fluke control are:
1. Pasture protection – to prevent liver fluke eggs reaching the pasture when snails are active
2. Pasture management – to reduce snail habitats and therefore reduce snail numbers
3. Grazing management – to avoid grazing high risk pastures with susceptible animals at high risk times of year
4. Strategic treatments for at risk animals – controlling the right stage of liver fluke, at the right time, using the right product.

Eradicating BVD in Welsh Herds

Support from the Welsh government to eradicate BVD in Welsh herds

Bovine Viral Diarrhoea (BVD) continues to negatively impact herd performance and productivity across many Welsh farms and is estimated to cost beef farmers £45 per cow per year. Support is now available by the Welsh Government to reduce the financial burden of BVD as they launched a new scheme on the 1st of September 2017 that will run for three years. Free blood sampling will now be available for youngstock during routine TB tests in order to identify infected herds with additional financial support of up to £500 available for herds found to be infected.

Restoring calcium and energy balance post calving

With the autumn/winter calving season upon us, it is important to consider ways to keep cows healthy at this crucial time. There are many challenges during the transition period but the biggest challenges can be the result of the metabolic changes that occur around calving and as the cow transitions into lactation. The main challenges are; trying to maintain hydration when water intake is reduced; mobilising calcium for colostrum and milk production; maintaining energy intake when dry matter intake is reduced.

Managing parasites for productivity during housing

Housing provides an opportunity to address the range of parasites picked up over the grazing season, to maximise cattle health and productivity over the winter.

The questions of which flukicide to use and when to treat can be challenging, complicated further by the increasing concerns over triclabendazole resistance. Understanding the properties of available flukicides is key to making informed treatment decisions.

How to body condition score ewes?

In order to increase performance in any flock, it is important to consider regular body condition scoring (BCS) in oIllustrating Transverse and Spinous processesrder to identify any drastic changes in ewe condition not noticeable through observation alone. Through this you can ensure that ewes are on target for the system and the time of year, and in turn will result in improved fertility, increased lamb performance and reduced incidence of metabolic diseases.
