Testimonials
Gary & Meinir Howells - Shadog
Gary and Meinir Howells over at Shadog have been using MonoShield for 2 years, and ever since have noticed significant improvements, from it being easy to use to benefitting the lambs overall health.
“When you’re tired and you’ve had enough of lambing and you haven’t got many hours in the day to do other stuff, you need something quite quick and easy to use, it is easy to use."
"I don’t think we could go off this now."
Nick Hulme - Easy Rams
Nick Hulme has been using All Guard 5in1 Bolus on his farm in Shropshire, where business is centred around producing towards 700 commercial rams a year. For 8-9 years now, Nick has been using the 5in1 bolus and has seen great results in both performance and scanning ever since.
"Follow up blood tests showed that everything was spot on, trace element wise, and our scanning percentages have been really good”
“[It] Simply has all the trace elements we require in one single capsule that's very easy to administer”
Neil Oughton
Neil Oughton runs an outdoor lambing flock of shedding sheep and highlanders and a charolais flock of around 130 ewes, over at Lymore Farm in Montgomery. Since introducing the Mayo boluses into their routine, every six months, they have noted significant improvements in their flock’s health due to the esurance of the correct vitamins and minerals being issued.
“We find them easy to give, and they work”
“We’ve done extensive blood testing before and after, forage testing, soil testing, and we’re finding the boluses are working”.
Ed Morgan
Carreg Farm’s own, Ed Morgan, milks 240 autumn calving Holsteins on his farm in Mold, North Wales. The team have been using the All Guard Iodine Max 5in1 Bolus for 6 years, and they could not be happier with the results, and how simple it was to introduce into their routine.
“I feel that through giving the bolus we know we’re giving them extra vitamins and minerals they need, and it’s just helping in the long run really with running the herd”
“It’s something simple, it’s become routine for us”
Robert Hunter
Robert Hunter milks between 160-170 jerseys all year round, with 200 cows total at West Tarbrax Farm at Shotts. Robert has been using Maycillin Boluses for around 3 years now and has been blown away by the outstanding results.
“The difference on going on to Mayo Maycillin was just night and day to what we’d been using before”
“The fact that I’m using it three years in, proves that it’s working”
Dominic Naylor - Lilburn Estate
Dominic Naylor, farm manager at Lilburn Estate in Northumberland, calves 2,100 stabilisers and has 7,000 ewes. The estate has been using a range of different Mayo boluses such as, the All Guard Iodine Max 5in1 Bolus, the All Guard 4in1 Ewe Bolus, and the All Guard 4in1 Lamb Bolus for 8 years now and has been amazed by the results and is confident that any missing elements are now being covered.
“We got on to the Mayo bolus and we have had no problems since then”
“I think a year like this, where we’ve had heavy rainfall and everything’s been washed out of the ground, it’s absolutely essential that you bolus your livestock, and the bolus for me is the Mayo bolus”
Paul Slater - Dandy Farm
Paul Slater and the rest of the team at Dandy Farm lamb between 1,600-1,700 sheep a year. Since moving onto Mayo boluses the team at Dandy Farm have not looked back, and are simply amazed by the improvements.

Sam Sawday - High Country Romneys

Since introducing Mayo All guard Ewe boluses into their routine 5 years ago, Sam is satisfied that essential trace elements are now able to be provided and is amazed with how easy they are to use.
“We started using the Mayo Bolus about 5 years ago, and really like the ease of application”
“It’s great to have that peace of mind that that bolus is in there and it’s slowly releasing those trace elements”
Dylan Roberts
Dylan Roberts, runs 130 suckler cows, on Fron Farm in Hendre, North Wales. Dylan has been using the All Guard Iodine Max 5in1 Bolus. Since introducing the bolus to their routine, Dylan and the team have spotted significant results and improvements in areas such as growth, and are assured that the cows are getting all the elements that they require.
“It’s absolutely essential that we do them two months prior to calving, it increases the quality of milk and it helps with fertility”
“Previously we used to buy minerals in 30 kilo bags, but we could never ensure ourselves that they were all taking it, with a bolus we all know that they’re taking the required amount”
Steve Pierce
Steve Pierce has been using both Rumen Proof and Maycillin Boluses at Holston Lodge Holsteins in South Leicester and is amazed with the results. He has noticed several improvements since introducing Mayo Healthcare products on his 110 Holsteins including increased milk yields and increased fertility rates.
“I really recommend it to anyone who’s looking to increase pretty much everything they want to do with a dairy cow.”
“I don’t think I’ll ever stop using it. It’s a really good product, and we’re really happy with the service.”
