New Holstein bull tops AHDB Dairy index run and five of the top 10 are new bulls.
A new number one Holstein heads the AHDB Dairy bull proofs published on today (Tuesday Dec 1). Kings-Ransom Erdman is one of the best daughter-proven bulls of the breed for transmitting longer lifespans (Lifespan Index +0.7) and also excels for daughter fertility (Fertility Index +12.4) and reduces cell counts (SCC Index -18).
Transmitting smaller than average stature to its daughters, the Planet son out of a Ramos dam also scores well for reducing the costs of maintenance (Maintenance Index -19), all of which earn it a Profitable Lifetime Index (PLI) of £603.
Erdman edges ahead of the former number one daughter-proven sire, Gen-I-Beq Lavaman, whose index continues to feature an impressive Predicted Transmitting Ability (PTA) for protein at 23.1kg based on 163 UK daughters milking. Its PLI remains at £599.
De-Su Ransom retains third position with a PLI of £591 and is the highest of the Roylane Socra Robust sons to feature near the top of the rankings.
Co-Op Robust Cabriolet is another son of Robust and as a new entrant in fourth is the highest ranking of five sires which were offered last proof run with genomic indexes and are making their debut in the top 10. With a PLI of £573 it confirms the genomic index earned as a young sire.
Climbing from 10th position is the Massey son, No-Fla AltaEverglade, who is the highest top 10 daughter fertility improver with a FI of +14.0. His PLI is £570.

Sandy-Valley-I Penmanship (Enforcer x Numero Uno), retains its number one position on the young sires genomic index with a PLI of £724. With high protein production (+26.2kg) amongst his many virtues it is the only sire to break the £700 barrier.
Also unchanged in second position is Stantons Checkers (Predestine x Freddie) whose Lifespan Index of +0.8 is the best of the breed. Its moderate sized daughters are predicted to stay in the herd longer than others and also expected to be cheaper to feed, seen in their sire’s Maintenance Index of -2.
In third position is Apina Nadal (Rocky x Goliath), which combines one of the highest Predicted Transmitting Abilities for weight of fat with solid daughter fitness.
A new entrant in fourth is No-Fla Junket (Balisto x Levi), transmitting good SCCs (-28) with all round fitness and predicted calving ease of +1.8.
The highest British-bred sire remains the fifth-ranking Topcroft Pesky Trix (Pesky x AltaIota) with a PLI of £665.
One of the two British Friesian bulls which previously shared first place in the breed £PLI ranking has edged ahead, thanks to slight gains in daughter fertility. The higher production bull, Catlane Chad (by Centurion) sees a rise in PLI to £389 while his stable mate, the higher milk quality Catlane Caleb (by Corsair) moves into second position. Caleb’s PLI is £383.
Retaining third place is Deangate Quaich (PLI £334) while making a reappearance in the top five is the high reliability sire, Lakemead Randolf. Now with over 400 daughters in his production proof, this Rocket son transmits a balanced index offering both production and fitness and earns a PLI of £317.
The fifth ranking Skyhigh Patrol (PLI £301) is the highest type transmitter of the leading PLI sires with a Type Merit of +1.24.
The top of the Jersey ranking remains unchanged with VJ Link continuing to lead with a PLI of £472. This Legacy son transmits high daughter fertility (+11.7) and a positive Feet and Legs composite (+1.3). He is followed by VJ Hilario (PLI £443) who transmits a high weight of protein (PTA ptn +15.5kg) combined with good fitness. Components specialist VJ Lure ranks third (PLI £391) with a high fat PTA (+24.2kg) while health specialist, DJ Holmer is fourth, adding UK daughters and earning a PLI of £381. DJ Lix rounds off the top five offering a high fat percentage, a lower volume of milk and a PLI of £376.
The Ayrshire ranking shows little change since August with Swedish born Gunnarstorp leading the way. Now with 42 UK daughters contributing to his production figures, he continues to impress with high fertility (FI +10.5), strong longevity (LS +0.5) and high type (TM +2.1). His PLI is £516. In second and third place are the familiar VR Gobel (by Gunnarstorp) and Pell Pers. New to the top five is VR Tuomi, who displays a balanced transmitting pattern across production, fitness and type. The high reliability sire Jelyca Oblique enters the top five for the first time, already with over 400 UK daughters contributing to his index (PLI £346).
New £PLIs for several other breeds include Shorthorns, Brown Swiss, Monbeliarde, Fleckvieh and Guernsey, can be found on the genetics pages of the AHDB Dairy website.
Farmers breeding for a predominantly grass-based spring calving system and using the Spring Calving Index (£SCI) will see little change in the ranking which continues to be dominated by the Jersey sire, VJ Tester whose SCI is £442.
Tester is followed by VJ Link in second (SCI £408) and British Friesian sire, Catlane Caleb, in third (SCI £402). Caleb is the highest fertility transmitter in the top 10, followed closely by VJ Link.
