Holstein UK are saddened to hear that Mike Tucker has passed away.
Mr Moviestar Mardi Gras (Mogul x Planet) maintains his lead atop the rankings for UK daughter proven sires, with +3.34 Type Merit at 93% reliability. Another Mogul son whose daughters have been pleasing the UK classifiers is Delaberge Pepper (Mogul x Planet), reflected in his +3.33 TM at 87% reliability, good enough for second place. In third is TW Goodwhone (Mogul x Alpag Iron) at +3.11 TM with high reliability (97%).
There’s a dead-heat at the top of the new genomic sire rankings which – combined with four new bulls in the top 10, 10 newcomers in the top 20 and the introduction of three newly developed genetic evaluations (see panel) – makes this month’s young sire offering of particular interest to Holstein breeders.
A new number one bull in the shape of the Morgan son, Mocon, has taken his place in the proven Holstein sire rankings, published today (3 April, 2018) by AHDB Dairy. Mocon is a German-bred maternal grandson of Snowman and his Predicted Transmitting Ability (PTA) features high milk production (826kg), low somatic cell counts (-23) and a very favourable Maintenance Index (-22), indicating his daughters have relatively low maintenance costs for feed. He earns a Profitable Lifetime Index (PLI) of £689.
Farming Connect and AHDB Dairy invite you to Aintree Holsteins to find out more about how you can manage the potentially lethal and disruptive recessive disorders and haplotypes without compromising genetic gain. Owen Tunney from Willows vets will explain how a vet led approach at Aintree helped to identify problem animals and the steps taken to avoid mating two recessive Haplotype carriers. Darren Todd from HUK will discuss what the different Haplotype codes are, where they come from and their estimated frequency within the UK Holstein population. Also Marco Winters from AHDB Dairy will present new Indexes that can help improve calf survivability and reduce lameness.
