UK-bred Holstein bulls have achieved their best result yet in the latest sire rankings published by MDC breeding+.

In fourth place is newly proven UK sire Netherside Dynamo, available from Cogent.

Dynamo, just £5 behind the new number one, is the only new addition to the top 10 rankings and has a PLI of £76, explains MDC’s Marco Winters.

And taking top spot in the rankings is Mtoto son, Mascol, with an improvement in his components, lifespan proof and somatic cell counts.

German-bred Mascol has added seven points to his PLI, taking him through to a score of £81.

Second to the new number one is O-Bee Manfred Justice who now has a PLI of £79.

Just behind him in third place is the previous number one sire Delta Canvas, now with a PLI of £78.

Just one point behind Netherside Dynamo and up from 10th place with a PLI of £75 is Ricecrest Boone.

De Crob Dynasty holds onto his sixth place with a PLI of £74, followed by the first of the 16 Addison bulls in the top £100, Holim Rafael.

The other three all share eighth place with a PLI of 71 and are all UK-bred, adds Mr Winters.

They are MOET Lookout, who has doubled his daughter proof to 330 with second crop daughters, Picston Shottle who rejoins the top 10 and Watergate Delegate.

This latest proof run shows some reshuffling of places because of improved lifespan evaluations, which are part of the £PLI calculation, explains Mr Winters.”
