Tom murphy Kilkenny dairy farmer talks Precision Microbes calf

Kilkenny dairy farmer sees the results short term last spring and now goes long term with PM calf with great success.
Tom Murphy, a Kilkenny based dairy farmer, and new entrant has seen the benefits of Precision Microbes calf probiotic and postbiotic liquid.
While seeing it online he used it for gut stabilization during a calf scour outbreak. With good results and a fast speed of recovery, he has now moved to more long-term usage at 30mls daily per calf for 30 days.
He still gets bits of trouble as he says himself but the recovery is much faster and they don’t get knocked back as much.
Like farmers up and down the country, he is also seeing a reduction in oral antibiotic usage on his farm. As Tom says it’s a no brainier when you think about it.

John Buckley dairy farmer sees a reduction in transition issues in calves with Precision Microbes 

We visited John Buckley a dairy farmer based in Co Cork. He has seen massive benefits in calf health and gut health since he began feeding Precision Microbes long-term from birth to his calves.

He previously had issues with calves going onto milk replacer early from whole milk as part of his Johnnes control program.

The farm has seen a huge decrease in gut health issues and scours in their young calves.

John is feeding 30mls daily per calf long term. He has also added a liquid dispenser to his automatic feeding station to feed Precision Microbes through the milk for young calves.



John Wynne, dairy farmer Co Wicklow

We visited John last week to hear how PM is working for him. A game changer in gut health. John used our unique pro and postbiotic liquid in calves during the first 5 days on halofuginone. Like many farmers, he saw a difference in claves when they came off the probiotics. When he started back-feeding Precision Micorbes he could immediately see the difference and the positive impact on calf health and vigor. He is now feeding 30mls daily for the whole period right up to weaning. There are massive benefits to calf health on farm, and John has seen a big decrease in sick calves during the period of supplementation.


Connor Creith dairy farmer Co Antrim

Connor talks about his experiences with Precision Microbes calf Pro and Postbiotics. With some minor digestive issues in young calves, Connor works with his vets at Riada veterinary hospital.

He decided to start Precision microbes 30mls daily from day 1 in young calves. He saw the difference those first 14 days and now is going to feed calves through his automatic milk-feeding system.

The big advantage for farmers with PM calf is the difference they see and by helping digestive health you can help calf health. Happy calves, happy farmers.

Michael Gowing dairy farmer Co Offaly

We visited Michael Gowing to hear how long-term usage of Precision Microbes calf is working on his busy spring-based dairy farm in Co Offaly.

The dairy farmer is really focused on getting the basics right for calves.

Attention to detail around colostrum Plenty of milk to help young calves grow Plenty of straw bedding and good hygiene

Calves are also on 30mls daily of Precision Microbes through his automatic milk feeding system.

Peter and Paula Hynes dairy farmers in Co Cork 

Tommy Heffernan vet visited the Hynes family this week to talk about calf health and microbes. A very well-known farming family and big agvocates.

They discuss successful calf rearing and the need for being consistent around the basics. They also talk about the difference PM calf pro and postbiotic liquids have made on their dairy farm.

They are now feeding 30mls per calf a day and seeing the difference in calf performance and health.

Kevin O Hanlon Dairy farmer in Co Wexford

Kevin is the farm manager of 150 cow dairy farm in organic conversion. Like every farm, calf health was challenging, with scour and pneumonia being the two big challenges. While calf mortality was not an issue, it was the setbacks calves receive following an outbreak that Kevin found the most frustrating.

He started Precision Microbes in the calves this autumn. He is feeding 30mls per calf per day right up to weaning. He is delighted with the results. Better calf performance and considerable improvements in calf health.

They have seen no disease issues in calves this autumn and a very big difference in calf thrive.

Listen to what Kevin has to say about the difference Precision Microbes has made on the farm.

Brian Delaney Co Laois on calf rearing and Precision microbes

Talks calf rearing and Precision Microbes. With the transition period for bought-in calves being challenging, Brian has seen a significant difference since putting his calves on Precision Microbes liquid pro and postbiotics.

He feeds 30 MLS daily for 4 weeks during the weaning period. Brian has seen….. Better appetites, less calf diarrhoea, and digestive upsets. Reduced infections and treatments needed during the weaning period.

Protocol for calf rearing dairy to beef is 30mls daily per calf in the milk for the milk feeding period.

Vet Philip Walsh from Orchard Veterinary Centre talks about Precision Microbes

Philip talks about what he has seen with customers using Precision Microbes. Like many vets reporting to us, appetitive and calf thrive are excellent when calves start on the product.

Most farms are using our 30mls for 30 days approach now.

30mls per calf a day from birth. 

Elaine Hickey dairy farmer talks PM pro and postbiotics

Elaine and Pat Hickey are dairy farmers in Co-Westmeath, they also have two farms in Roscommon. Elaine rears all the heifers on the home farm with a big interest in calf health.

She was even surprised herself at how effective PM was at helping calves recover from dietary upsets. They are now making PM part of their routine from birth to every calf and will be feeding it through the automatic calf feeder.

James Toner, dairy farmer in Co Armagh, talks about the results of using PM calf pro/postbiotics.

James is using precision microbes from birth in his calves. He has seen a massive improvement in calf health over the last 3-4 months.

Phelim Kavanagh Wexford farmer talks about adding PM to the calf rearing toolbox

After initially being skeptical Phelim is now adding Precision Microbes to his calf rearing toolbox. Every calf will be getting 30mls on arrival and 30mls daily up until weaning.

Better calf performance, reduced disease issues and a quick response when issues did arise.

Eamon Sheehan talks about the role PM calf pro and postbiotics is making on his farm 

A progressive dairy farmer with an interest in AMR, Eamon has been using Precision Microbes for two years in his calves. Improved performance and the reduction of any nutritional upsets for him are the big wins.

Less intervention with sick calves also and better health overall. He also discusses the use of other blends on farm and the difference they are making. 

Michael Connell Dublin dairy farmer sees the benefits of Precision Microbes

Feeding it in daily in milk to young calves Michael has seen the benefits of better health and reduced calf scour.

Listen to his feedback 

Veterinary surgeon Tadhg Gavin talks about Precision calf pro and postbiotics reducing antibiotics usage.

We visited Tadhg Gavin from Killaloe vet clinic, a member of Xlvets Ireland.

He spoke about how Precision Microbes have very positive impacts on calf health.

We were also delighted to hear him talk about reducing antibiotics in their business and for their customers.

Donal and Marie Liston from Limerick talk about Precision Microbes calf probiotic and postbiotic.

They already have bought half of next year’s supply. A strong endorsement from the Liston’s on how effective Precision Microbes has been this year. While initially using 50mls daily to help calves with scour/diarrhoea recover, they moved to long-term usage, giving 30mls daily to young calves from birth. We are delighted to see customers like Donal and Maire get the results with PM calf probiotics and postbiotics.

Elizabeth and John O’Brien discuss using precision microbes in their young calves.

The O Briens farm and milk 220 dairy cows in Co Wexford There is a big focus on calf health. In spring 2021, they used precision microbes’ unique liquid of liquid probiotics and postbiotics. They have seen increased growth rates, less scour, and a reduction in antibiotic treatments. Liz said, “We just found this probiotic unbelievable.”

Precision microbes with Michael Rossiter, farm manager in Redmond’s farm Gorey Co Wexford.

The Precision Microbes team caught up with Michael Rossiter farm manager in Redmond’s award-winning dairy to beef farm. They rear 550-600 Angus heifer calves yearly in a farm-to-fork production system. They used the probiotic and postbiotics last spring in a group of 100 calves they weren’t happy with. The product turned these calves “inside out in a couple of days” according to Michael. Continued success to Redmonds farm, and thanks for sharing, Michael

Anthony Burke talking about Precision Microbes and calf rearing.

He farms in Tipperary and is contract-rearing dairy heifers. This year is the first year he is using an automatic feeder. Anthony explains when starting to use Precision Microbes, life got easier. The calves are on 30ml daily for the first 10 days, and then he reduces the daily dose to 15 ml daily. Anthony has seen better appetites, dung consistency, and great thrives on his calves. Precision Microbes is a game-changer in calf health and works well for anyone rearing calves. Especially helping them get over the first week and the stresses associated with changing diets and environments.

Gerard McEvoy talks about the difference in his young game birds on Precision Microbes

The team at Precision Microbes worked with Gerard McEvoy on his 2000 pheasant flock. They rear the pheasants for a private shoot and were interested in rearing healthy birds with a huge focus on gut health in young chicks. The trial started from arrival to five weeks of age (0-5 weeks PM poultry daily in feed). When we visited him at 8 weeks, he said they were a week ahead of where they would normally be at 8 weeks. stronger, healthier birds. He has seen fewer antibiotics and had way less disease. he also remarkably seen a halving of mortality in the 5-week period.

Joe and Ellen O Neill talk about farming and PM microbes

Tommy went to visit Joe and Ellen O Neill last week to talk about Precision Microbes calf Pro and postbiotics. It was so uplifting to see how our calf product has made such a difference on their farm this year.

Particularly the improvement in calf health, less disease, and massive reduction in calf scour and antibiotic usage. 

Niall and John Mason talk about Precision Microbes calf pro and postbiotic liquids.

We visited John and Niall on their dairy farm just outside Tralee Co Kerry. They milk 85 cows and their attention to detail is second to none. With good calf health, they spoke about how Precision Microbes were an extra tool for them this spring to improve calf health even further.

Tom Flanagan, large animal veterinarian

For me, it was when farmers started coming back for the products themselves because of the results they saw. The feedback from farmers has been overwhelmingly positive. We also have now started seeing the benefits in more long-term use with farmers on calves being bought in and reared.

We are using 30mls for 30 days protocol which is working really well for calves.

These are exceptional products across all species in fairness.

Tom Flanagan

Bower Park Farm, Kent.

We have had great success with this product. Mainly using it as a relief when early symptoms appear in the majority of cases the symptoms have been fully cleared before the calves have taken any ill effects. The calves seem to like the taste of the product so when syringing the calves never stress and when added to milk we have never had one go off or not drink the milk. Very happy with it, will definitely be purchasing more.

Precision Microbes calf is available through Wynnstay in the UK.

Martin Crowe B.Agri.Sc Dairy farmer and Agricultural consultant Co Limerick

“I used Precision Microbes in spring 2022 initially to help calves recover from digestive upsets and scours. Having heard other farmers giving it positive feedback online, so that’s why I tried it. I was delighted with the results. I  could see them improving quickly compared to anything I’ve used previously.

I then decided to use it in a more preventive way, where I put calves on it from birth daily while they were in single pens. I was delighted with the results. It will be used again this spring for sure.”

Tom Flanagan

Padraig Brennan from Glasslyn Vets, Bandon

”From talking to clients, I have found the recovery from scours much faster in calves who receive Precision Microbes probiotics and psotbiotics. 

We also noticed calves that received probiotics from day 1, have fewer digestive upsets in times of stress.

I also contact rear dairy calves at home and most years we get an outbreak of rotavirus,  since we started giving them probiotics a week before they travel to my farm, the cases of scour are less, and recovery is much quicker. 

Next year we will administer probiotics through an automatic calf feeder so they will get them until weaning”

Francois Walch veterinary surgeon in Clifden Co Galway

Precision Microbes is selling very well and no negative feedback from farmers at all. I have always preferred a natural solution where possible and this seems to be working great.

Aoife Doogue veterinarian in Mid Kerry veterinary centre Co Kerry

“As a mixed practice vet, I have had the opportunity of using

precision microbes as a probiotic and postbiotic across a variety of

species. To say I am impressed with the product would be an


The speed of recovery from acute and chronic gastrointestinal

issues are halved, and outcomes of what can be complex cases are a

a lot more positive due to this great Irish veterinary product.

Trying to encourage owner/farmer compliance can be a huge

the challenge in veterinary medicine, but when they see rapid results

such as from precision microbes; owners and farmers alike are

hugely onboard with your treatment.

Not only as a product is precision microbes ahead of its game but as

a company as a whole. The veterinary sector is moving and

changing all the time, and precision microbes’ vision and innovation

in animal nutritional science is helping and improving our method

of treatments. Precision microbes are listening to the input and

clinical needs of vets in treating our patients, which gives great trust

in a product.

I will be continuing to use Precision microbes due to its immense

results and supportive company.”

Damien Shaughnessy Pedigree breeder Co Roscommon

The purebred Charolais calf in the picture was treated with precision microbes for a grass scour. Two days of Precision Microbes treatment were administered to the calf and the results were super. A great product to solve issues without the hassle of antibiotics and upsetting the calf’s temperament.

After using the product a few times now and I have been really impressed.

Kieran Devaney, vet with Ormonde vets Co Kilkenny

Spring 2022 was our first-time using precision microbes. Our experience is best summed up in the feedback given by one of our farming clients remarking ‘that’s mighty stuff,’ and it is. Precision microbes help prevent and treat nutritional and infectious scours in calves. I found they had a really positive impact in a number of scour outbreaks in March past, with calves bouncing back faster than in previous years. We’ve also used it to help purchased calves settle onto new feeding regimes with similar success. All in all, a fantastic product! I can’t recommend precision microbes highly enough

Sheep vet John McHugh Baltinglass Co Wicklow

We trialed Precision Microbes’ advanced gut Stabiliser for lambs in six flocks in the spring of 2021. Each flock we chose had previous issues with watery mouth in young lambs, *some also had joint ill issues*. With no oral antibiotics available and the need to move away from them, we were looking for an effective replacement.

All six flocks used the product at birth 6mls orally. We closely monitored issues like watery mouth during this period. None of the flocks using the products had any problems, and we were delighted with the results.

Along with improved management practices, this product has really delivered in our flocks. It is great to have something to work on speeding up the natural defences in young lambs.

Paul Ryan MVB MRCVS Waterside veterinary Ltd Limerick 

I found Precision Probiotics an excellent addition to the treatment of calf scour. Irrespective of the causative agent of the calf scour. I found the probiotic in conjunction with other treatments greatly improves the calf gut health during a scour episode, shortening the recovery time, and increasing survivability. Results in a positive outcome for both farmer and vet.”

Robert Tobin, dairy farmer

We had a bad Rotavirus Outbreak this spring. Calves were extremely dehydrated and off of milk completely. Before we would have just given them electrolytes and it could have taken over a week to get them back on track and in a lot of cases we would have lost calves or they would have gotten a secondary infection Now we go in orally with precision microbes for 7 days along with electrolytes and by day 3 the calves are 90% better and no longer need the electrolytes. Also, the Calves that had the rotavirus infection always would have dull coats and lag behind the calves that didn’t get the rotavirus for the rest of the year. Now with the precision microbes, we see no difference in calf performance post-infection and their coats look fantastic. We lost no calves from the rotavirus outbreak while using the precision microbes either.”

Adam Conn BVMS MRCVS CertDHH, Riada Vets, Ballymoney,

A great product to have in our toolbox against scour. Calves recover faster and thrive quicker after treatment with precision microbes. I have no hesitation in prescribing it for either part of the treatment plan or prevention against any of the causes of calf scour.

Dennis Howard vet and suckler farmer Co Cork

“As a vet and a farmer, I know the challenge of calf scour and getting calves to recover. Traditionally when we had a calf with scour the treatment would be fluids, antibiotics, and anti-inflammatories.

Since I started using Precision Microbes it’s been a game changer in gut health in my calves.

My routine now is fluids if needed, an anti-inflammatory, and oral dose of precision Microbes for a calf with scour.” I have found when I get in early, it can be a short course for 2-3 days.

The results are better, and the peace of mind of having something more effective than antibiotics. In an era when we need to reduce antibiotic usage, this is a lifesaver to have something so effective at getting calves to recover quickly and effectively.

Peter Hynes dairy farmer Co Cork

Had a nutritional scour on our farm that was causing problems with our calves. Had tried loads of different products with little success. Within 24 hours all calves were back drinking and standing up again and within 72 hours all calves were back to their full amount of milk and looking much healthier and lively. Our goal is to keep our calves as healthy as possible during their time with us and Precision Microbes helps us do that.”

David, Joan, and MJ Scallan dairy farmers Co Wexford

“We run a spring calving dairy herd in Wexford and on the recommendation of Tommy, we started using Precision Microbes on our calves this spring.

Over the last few years, we have been concerned about the use of antibiotics on our farm, especially during the spring on our calves so we were delighted to use a product that would potentially help us reduce the amount both from a cost and an antimicrobial standpoint. We would have to say the product definitely helped with the reduction of antibiotics and calves also recovered quicker and had fewer setbacks after using the treatment.

We wouldn’t hesitate in recommending Precision Microbes to other farmers on the back of our experience this spring.


Bruce Thompson dairy farmer Laois

“We were having a lot of issues with bloat and scour on our farm with calves 2-3 weeks old. Within a couple of days of using precision microbes, the calves cleared up. I found it works almost immediately for bloat. I couldn’t do without it now for calves.”


Robert Dowley pig farmer Co Kilkenny

Gut health is everything to rearing healthy pigs. We are very focused on being ahead of the curve on the challenges we face in our business.

We used Precision Microbes pro and postbiotic pig gut stabiliser in our younger and weaker pigs. Each week we targeted the weakest litters and it turned them around with weekly dosing.

It turned them around, you could see a very visual difference in the pigs and I was thrilled with the results.


Ronan Siochru dairy farmer in Dingle Co Kerry

My calves had nutritional scour and came across PM on Twitter. I put the calves on a 5-day course of PM and by the third day the calves’ scour had cleared up and their appearance and overall health had improved massively.


Ronan Kennedy veterinary surgeon Moss Vets on PM lamb AGS 

With a push to reduce antibiotics in our flocks and farmers looking for alternatives, we used precision microbes advanced gut stabiliser for lambs in several of our flocks this spring as a trial.

Precision Microbes calf pro and postbiotics was very successful on our farms. We were speaking to the company and wondered had they anything in the pipeline for lambs.

We got involved in trialing their new lamb product in several flocks.
I have to say the results were good, with no issues in any of the flocks we used it on. Along with good management, these flocks had no issues with watery mouth.

While good management plan is the key to reducing the risk of watery mouth it is nice to have something to give farmers that will promote better gut health in newborn lambs.

Since prophylactic use of antibiotics is no longer allowed the use of precision microbes advanced gut stabiliser for lambs will be an important tool in preventing watery mouth and promoting better health in our flocks

Eoin Moriarity calf rearer Co Kerry

I found this product amazing when calves transitioned from pure milk to milk replacer without any upsets to the calf when bought in and any calf that went of drinking it was definitely back drinking 24hrs after using this product.

Couldn’t recommend highly enough to anyone rearing calves.

Phelim Kavanagh calf rearer

I used precision microbes in our contract calf rearing for the first time in Spring 2022. I am a skeptic by nature and it was the calf owner’s farm manager, that gave me the product and asked me to see what I thought. I conducted an on-farm trial to monitor any significant change in treated calves. The result was a marked improvement in the general health of those who received Precision Microbes over the untreated batch. Treated calves were not as prone to illness and as a result, needed less antibiotic intervention. By extension, this led to higher live weight at weaning. The better general health in calves equaled less work in intervention thus saving valuable time. Both Michael and I agreed, Precision Microbes should be included in the calf-rearing toolbox.

Flicck Bryant & Edward Leighfield
Dairy Farm – Wiltshire – All-year round Calving

We started using precision microbes when it was recommended to us by our calf specialist after experiencing an issue with scours amongst the younger calves.
We initially started giving the calves with scours 50ml a day in the milk and we were so impressed by their recovery. Within 24-48 hours the calves were more alert,
active and there was an increased milk intake along with eagerness at feeding time.
Due to the significant results, we started giving 30ml a day to all calves up to weaning. Whilst using the microbes we saw an increase in appetite,
overall calf performance, and a reduction in calf upset. Understandably we still have our challenges with scours, however, the comeback in health and response to the microbes are impressive.
