New type merit sees Mogul sons and grandsons rise to the top in December 2017 Holstein ranking lists
As dairy farmers we like to learn something new every day. With that in mind, some of the most successful farmers in the dairy business will share their stories at the Semex International Dairy Conference on Sunday 14th – Tuesday 16th January 2018 at the 5-star Radisson Blu Hotel, Glasgow.
Genus ABS reaffirm their status as the leaders in delivering Profit from Genetic Progress with the addition of seven new genomic sires averaging over £717 PLI to their line up following the December proofs.
One of the top milk quality improvers of the Holstein breed, Mr Rubi-Agronaut, leads the way amongst genomic, young sires in the new AHDB Dairy indexes, with a December 2017 Profitable Lifetime Index (PLI) of £812. Retaining the position he has held throughout the year, Agronaut transmits fat and protein percentages at +0.22% and +0.09% respectively, and also has the highest Type Merit of the top 20 sires at +3.12. This type score reflects the new emphasis on bulls with smaller stature in Holstein UK’s newly revised Type Merit formula.
The number one position in the new Profitable Lifetime Index (£PLI) rankings for daughter-proven Holstein bulls is held by long-term leader, Gen-I-Beq Lavaman. This bull has almost 100 more UK daughters contributing to his figures since they were published by AHDB Dairy last August, now clocking up more than 1,000 milking in the UK. He earns a PLI of £690, reflecting his balanced breeding profile, with a very high Predicted Transmitting Ability (PTA) for protein percent (+0.18%) and low daughter maintenance costs (-9).
