Peak AltaValuePack
Taking the lead with a Profitable Lifetime Index (PLI) of 拢877, Peak AltaValuepack by Peak Excitement claims the top spot thanks to a well-balanced profile featuring strong health traits.
These contribute to a high HealthyCow rating of 拢203, meaning it is predicted to transmit 拢203-worth of health and fertility benefits on average to its daughters; a favourable Maintenance Index of -17, indicating daughters will require less feed for maintenance; and solid Predicted Transmitting Abilities (PTAs) for production, including +0.17% fat and +0.10% protein.
With a PLI of 拢876, Denovo 20771 Segment by Leeds, edges up to second position, with a Calf Survival rating of +2.6.
Number one sire from the previous ranking, Denovo 20893 Harmony, is now in third position (PLI 拢875). Harmony continues to excel in PTAs for weight of milk (1116kg), fat (54.6kg) and protein (41.3kg), as well as feed efficiency (-28 Maintenance, 294 Feed Advantage (FAdv) and retains the highest score for EnviroCow (+5).
Progenesis Preston is in fourth with a PLI of 拢862, delivering high milk solids (54.3kg fat, 41.5kg protein), while fifth ranking Denovo 20723 Columbia (PLI 拢856), is one of the highest yield transmitters passing on 1135kg milk and, like its sire, Leeds, has a strong Fadv. At 237, this means its daughters will save 237kg of dry matter intake during each lactation.
Marco Winters, head of animal genetics, AHDB, said: "It is encouraging to see such good stability among the top 20 拢PLI sires in AHDB's latest analysis, with several bulls maintaining strong positions and some exciting new entries offering fresh genetics. This gives farmers a robust and diverse selection to build into their breeding plans for the upcoming season."

Six new sires enter top 10 proven 拢PLI ranking
Six new daughter-proven sires graduate into the top 10 ranking for Profitable Lifetime Index (拢PLI). These Holstein bulls move up from the genomic young bull rankings and now demonstrate, through their daughters, how they can contribute to improving health, fertility and production efficiency across UK herds.
The top four positions are occupied by newcomers, with OCD Trooper Sheepster leading the way. With a PLI of 拢779, Sheepster has strong Predicted Transmitting Abilities (PTAs) for production, (47.8kg fat, 35.7kg protein) alongside a lifespan improvement of +113 days.听

New in second position is Peak AltaSeverus (PLI 拢757), transmitting outstanding daughter fertility (+12.8) and an excellent ability to lower cell counts and mastitis (-25 SCC, -1 Mastitis).
SDG-PH Delux Dominance (PLI 拢741) ranks third, offering a short gestation length (-4 days) and good calf survival (+2.8). In fourth place is the high fat (+0.33%) Winstar Maserati听(PLI 拢728), whose strong daughter Fertility Index (+9.6) contributes to a HealthyCow of 拢215.
With more than 2,000 UK milking daughters now in its production proof, former long-term frontrunner, Genosource Captain, holds fifth place (PLI 拢723), ranking highly for feed cost-saving traits, including Maintenance (-28) and Feed Advantage (+255).

Vikings excel at top of the Jersey rankings
In the AHDB Profitable Lifetime Index (拢PLI) rankings for the Jersey breed, VJ Outrup Luxi Luxplus (PLI 拢472) climbs into number one position, combining solid production (226kg milk, 46.1kg fat plus protein) with an EnviroCow score of +2.9 which makes it one of the most environmentally efficient Jersey sires available. This bull also excels when compared across breeds, as does the number two Jersey, VJ Ravninggaard Huus Hamlet (PLI 拢443). Hamlet rises from fourth to second position, thanks to standout health and fertility traits. This includes a daughter Fertility Index of +16.8 and a HealthyCow of 拢232, supported by data from 519 UK daughters.
Ayrshire
The new Ayrshire听 leader is VR Wehmais Vimo Vehmaa (PLI 拢560) which combines solid production, particularly for fat (35.2kg, +0.36%), with strong health and fertility, resulting in a HealthyCow of 拢175.
Holding second is VR Hakvin (PLI 拢521), the breed leader for both Lifespan Index (+109 days) and EnviroCow (+3.3) which offers impressive production at 436kg milk and 53.7kg fat plus protein.
Friesian
In the Friesian ranking, Inch Next (PLI 拢316) retains the top spot, with exceptional production (296kg milk, 28.4 kg fat plus protein), solid lifespan (+58 days), and the best EnviroCow in the breed at +1.9.
In second place is Bloemplaat Hoeve Ewoud (PLI 拢287), a consistent performer at 12.7kg fat and 10.5kg protein, with strong udder health (SCC -11), and a good daughter Fertility Index of +6.7.
In the Friesian genomic young sire rankings, Goonhilly Coverack leads with a PLI of 拢320, combining good milk components (+0.14% fat, +0.11% protein) with strong health and a high daughter Fertility Index of +3.9.

Clean sweep by AltaSeverus for seasonal calving herds
Exceptional daughter health and high-quality milk production have earned the newly proven bull, Peak AltaSeverus, number one position for both seasonal calving indexes 鈥� Autumn Calving Index (拢ACI) and Spring Calving Index (拢SCI).
听
An ACI of 拢733 and an SCI of 拢599 reflect the suitability of AltaSeverus' daughters for block calving herds, whether winter-housed and with higher concentrate intakes or whether calving in spring and with production based largely on grazing. AltaSeverus stands alongside several other new entrants in the 拢ACI ranking, the second of which, Winstar Maserati, has similar transmitting qualities including desirable daughter lifespan and fertility. Its ACI is 拢714.
Holding third place is Winstar Graziano (ACI 拢705), known for excellent milk components and SCC.
The 拢SCI rankings are tightly contested, and just one point behind Peak AltaSeverus, who excels in weight of milk solids and udder health, including a standout SCC rating is Winstar Graziano (SCI 拢598). This consistent performer also excels for SCC and fat and protein production. Denovo Invictus is at number three with an SCI of 拢589, transmitting exceptional fertility and maintenance and now with 2,997 UK milking daughters.
