PD results show 23/25 SexedULTRA 4M® pregnancies due to Kirkby PREMIER at Organic Friesian herd in North Yorkshire!

"This is the first time we've used 4M® and it has done the job absolutely brilliantly. Heifers have been served once and have held straight away. Our Genetics Sales Consultant Richard is great, and always keeps in touch! This year we are using Goonhilly JOSEPH and are looking forward to seeing the results!"
