Every farmer knows that the run‑up to calving and those first weeks after are some of the most challenging days in the whole calendar. Cows are under pressure, staff are stretched, and small problems can quickly snowball into bigger ones. At Kersia UK, we’re committed to helping farmers get through these moments with confidence, and to support them in rearing the healthiest, most productive herds possible.
That’s why our team, alongside partners like RAFT Solutions Ltd, is focused on practical, reliable tools that fit real‑world farming. One of the most effective of these is our precision bolus range, designed to give individual cows the exact support they need at exactly the right time.
As Mark Atkins, Kersia UK’s Key Account Manager, says:
“Farmers don’t need more complication, they need solutions that work, even on the busiest days.”
And that’s where boluses are proving their worth.
Why Transition Support Matters
The transition period, the three weeks before calving and the three weeks after, is the most important phase in a cow’s lactation. But it is also the trickiest. Cows can struggle with changes in diet, dropping energy levels, social stress, reduced intakes and the demands of calving itself.
This is where many common problems begin, including milk fever, ketosis, retained placenta, displaced abomasum and slower returns to breeding. When cows start off on the back foot, everything after becomes harder.
How Precision Boluses Fit In
Even with good feeding and management, some cows just don’t get what they need from the ration alone, maybe they’re timid, maybe they’re over‑conditioned, maybe they’re carrying twins, or maybe intake is reduced because of stress.
Boluses offer a simple fix: they make sure every cow gets her full share of key nutrients, no matter what happens at the feed face.
Alex Gomez, Kersia Group’s Technical Development Manager, explains:
“Boluses aren’t a replacement for good feeding, they are a safety net. They take the guesswork out of those high‑risk moments.”
Our range uses ‘Dual Bolus’ technology. That means each dose has one fast‑acting bolus that starts working within minutes and one slow‑release bolus that keeps supporting the cow for 24 hours to 10 days, depending on the product.
A Quick Glimpse of Kersia’s bolus range
Bolifast® Physiologic (10–15 days pre‑calving)
Helps prepare the liver for calving and early lactation.
Great for: over‑conditioned cows, twins, stressed heifers.
Bolifast® Rumen (right after calving)
Gives the rumen a “kick‑start” after the dry period, helping cows settle into their new diet quickly and avoid off‑feed events.
Boliflash® Fertil (15 days before service)
Supports heat expression, fertility and early embryo development, ideal for tight breeding windows.
Why Farmers Tell Us They Like Boluses
Farmers also tell us that ‘bolusing’ fits easily into existing routines; calving checks, pre‑breeding checks, fresh cow checks; without adding more work to do.
Committed to Service & Support
At Kersia UK, our focus goes beyond products. We’re constantly working with vets, consultants, RAFT Solutions Ltd and on‑farm teams to make transition management easier and more effective. Whether through training sessions, farm support, webinars or practical tools like checklists, we want to help farmers feel confident during the most demanding periods.
We know times are tough. Herd pressures, labour shortages, unpredictable weather and continued financial challenges are pushing farms harder than ever. But small, well‑timed interventions, like bolusing the right cows at the right moment, can make a real difference to productivity, health and peace of mind.
As Mark says,
“Our commitment is simple: support farmers with practical solutions that make every day work a little easier and herds a lot healthier.”
If you’d like help choosing the right bolus strategy for your herd, our team is always here to support you.
