While the value of data is well understood by industries, such as retail or tech, is the sheep farming industry using its own data to its full potential?

Treat parasites according to risk, not by time of the year

With no two years the same when it comes to parasite activity, farmers need to be aware of what is happening on their farm and take appropriate action based on the risk, rather than the time of year in order to prevent costly production losses.

As the year progresses, it’s time to start thinking about the autumn parasite challenges, we’ve seen some very high worm egg counts this year which could continue into the tupping season. Continuation of the current warm, wet weather could result in us seeing an earlier fluke challenge too.

Results from farms involved in the Zoetis Parasite Watch scheme shows that areas which have seen warm and dry weather followed by sudden wet weather, such as South West Scotland and Wales have seen a rise in worm egg counts.

The 2017 worm threat: It's unpredictable

For most areas of the UK, feedback suggests that last year was one with low to moderate roundworm burdens. Where this was identified using good diagnostics, economies from using fewer wormer treatments were possible with manageable risk rather than a fingers crossed approach.

Sheep Quarantine: 5 Key Tips

If new or returning sheep are not quarantined it is not only a disease risk but can also waste your time and money. Resistant worms are then much more likely to be introduced to your flock with incoming animals and your usual treatments may not kill them.

NSA Sheep Event 2016: Our Experience

Whilst we all enjoy the Great British Summer, our team made the journey to attend the National Sheep Association’s NSA Sheep 2016 event at the three counties show ground in Worcestershire. With a multitude of stands filled with things from feed to shearers, weighing equipment to drenches – it was always going to be a fantastic day for attendees. This was the case for our team on the Zoetis stand as our team spoke to so many hundreds of farmers throughout the day, mainly about our dual active Knockout drench: STARTECT.

Watch out for Nematodirosis

Parasitic gastro-enteritis (PGE) (worm scours) will affect all lambs to a greater or lesser degree and as such are a key concern for sheep farmers everywhere. It can be caused by many different worm species, but the two most important in the UK are Teladorsagia circumcincta and Nematodirus battus.
