ABOVE De-Su Penley 11839 is the UK’s number three genomic PLI sire in the UK with a score of £673 (12/14).
Pedigree
Coyne-Farms Shottle Jam (Picston Shottle) Coyne-Farms Ramos Jelly (Ramos) Coyne-Farms Mass Jill (Co-Op Bosside Massey)
De-Su 1481 (Ladys-Manor PL Shamrock) De-Su Penley 11839 (Seagull-Bay Platinum)
flushed as a heifer before being sold to De-Su Holsteins. Mass Jill is the dam of some notable sires, De-Su Altajackman, De-Su Altajohnson, De-Su Nominee and Coyne-Farms Jacey to name a few. Penley’s dam is a Ladys-Manor PL Shamrock sister to Jacey, and Jacey is the number three sire in the UK for GPLI (£579). With daughters hitting the UK top lists, he has sired six of the top 20 GPLI daughters in the UK as of December 2014. Ramos Jelly was also flushed to Badger-Bluff Fanny Freddie when his semen first became available. The flush resulted in six heifers, Coyne-Farms Freddie Jill being one of them. Freddie Jill was flushed to Marbri Face- book (Man-O-Man x Airraid) and the outcome was high genomic sons, Coyne-Farms Jetset (PLI £559) and Coyne- Farms Jabir (PLI £532).
If we take a look at the paternal side of Penley, the family tree is just as interesting. Platinum is a Flevo Genetics Snowman son and he is also a maternal brother to Seagull-Bay Supersire, Seagull-Bay Headliner, Seagull- Bay MVP, Seagull-Bay Shaw and Seagull-Bay Sargeant. He is also the full brother to Seagull-Bay Diamond as the result of a split embryo. Their full sister is the noteworthy Seagull-Bay Snow Darling VG87 who is the dam of one of the most popular genomic bulls to date, Seagull-Bay Silver (PLI £616).
PROGENY: This June 2013 born bull has no daughters as of yet, but we wait with anticipation to see
his progeny.
COGENT SAYS: David Sayce: This early Platinum son sits at number three in the UK on the
current PLI list with impressive Lifespan and Fertility Index ratings combined with high Type and a cow family renowned for its transmitting abilities through the female line. Penley suits the discerning breeder chasing the latest genetics, or the farmer chasing every day efficiency. Penley’s mother is the Shamrock daughter De-Su 1482 ET, who is out of Coyne- Farms Mass Jill ET. She is regarded as one of the Holstein breed’s leading cows for her transmitting ability through her progeny, with 13 daughters at one stage averaging an impressively high GTPI. Now with more than 20 daughters as well as various sons in AI, this family’s success has come from a focus at Coyne-Farms for breeding for productive life. The third dam is Coyne-Farms Ramos Jelly who has numerous sons and grandsons in AI.
FINAL THOUGHTS: Derived from a strong female cow family recognised for their impressive fitness
traits, Penley is surely another sire to look out for. Without a doubt he is a real all-rounder with very few faults on his genomic index. Penley is the kind of sire that could benefit many breeding programmes on dairy farms in the UK.
