            MDC breeding+ has published the latest production proofs for all
              UK available bulls this week (17 January). This latest data for
              specialist dairy breeds, that ranks sires on Profitable Lifetime

              and Ayrshire breeds.

              Ahlem Lemvig Abe is the new top Jersey bull. A high milk sire,
              he has a PLI of £212. He is closely followed by the previous
              number one sire Sunset Canyon Maximus. The highest new entry in
              the Jersey PLI rankings is DJ Look who comes straight in at fourth
              place, benefiting from a strong daughter lifespan proof at +0.3
              lactations. 
               
              Hunday Major Red, with a PLI of £202, takes over as top Ayrshire
              sire from Morwick Sand Ranger. Major Red’s somatic cell count
              score of -18, indicating that he has the ability to breed daughters
              with a cell count of 18% lower than the breed average, and his
              lifespan score of 0.3 have contributed to him gaining top place
              in the breed. 
               
              Peterslund remains firmly in control of the top spot in the pure
              Ayrshire listings thanks to improved daughter lifespan ratings
              now at +0.5 lactations. 
               
              Blackisle Glen Albyn holds on to top spot in the Friesian PLI rankings
              with a score of £202. He improved further on his daughter
              lifespan, now at 0.3, and fertility ratings and is now well clear
              of second placed Dovea Bass with a PLI of £159. Third place
              is shared between Sem 7 and Grietman, both with PLI’s of £136. 
               
              Jensgolden Victory Hunter remains the highest ranked bull on the
              Guernsey Merit Index (GMI) at 460, followed by a new entry Coulee
              Crest Luxury Spider. Meadow Court Red Oak ranks third, transmitting
              the best overall fitness balance of the three with a good daughter
              lifespan of +0.2 lactations and a SCC of –14%. 
               
“We are continuously improving the genetic information provided
              for specialist dairy breeds and the latest development on type
              information, which were first introduced at the last proof run,
              will assist producers in making the most accurate choices of sires,” says
              MDC breeding+ director Marco Winters. “But producers must
              not compare sires between breeds – just within them – as
            each breed uses its own genetic base.”
