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.
