Both have 15,000 kg plus lactations to their names and have been fl ushed

extensively. Warnelview Goldwyn Ruby

2 VG87 jointly holds ninth spot with Goldwyn Lila at £290 PLI.

Infl uential sires

Unsurprisingly, the top UK indexes are dominated by Shottle, Goldwyn and Oman, much the same as the lists in other countries around the world. The top 50 PLI females all have PLIs exceeding £243, and are represented by 20 different sires. With 15 daughters in the top 50, Goldwyn is unchallenged as premier sire. His closest rival is Oman making double fi gures with 10 daughters, while Shottle has four daughters while Champion and Principal both have three. Storm and Lancelot each have two daughters in the top 50, with all the remaining sires only having a sole daughter making the top 50 list.

Classifi cation characteristics

Over the years, the myth that production and type can not go hand in hand seems to have been rightly eroded and this is easily seen by the latest top 50 PLI. It not only includes productive individuals but also ‘good looking’ or rather highly scored females. There are however also a number of animals on the list belonging to Holstein UK members who do not classify (eight animals have not been classifi ed on the list). Of the remaining females, there are seven scored in the highest grade with Denmire Storm Marie EX94-3E LP100 (PLI £268) the highest classifi ed cow in the Top 50 and, of course, she is the dam of the PLI

leader Goldwyn Marie 52. Storm Marie is

also likely to be one of the oldest cows on the list as she has completed six lactations during which she has amassed over 100 tonnes of milk lifetime, has bred three EX and 13 VG daughters so far and falls in the top 20 PLI herself. In tune with this is her Reliability at 86%, testament to her age and transmitting ability as she is the only female in the list to exceed 80% Reliability, with the other animals all falling between 50% and 80%. Other breeders of EX cows on the list

include the Inch, Riverdane, Ablench, Townhouse, Laurelhill and Lagangreen

herds. By the nature of the list, it is likely to be dominated by younger milking females as genetic progress dictates that newer and younger sires should supersede their elders. A further 30 of the

daughters and Maries dominate the Top LPI list. Denmire Marie 51 VG88 makes the top 10.

animals in the list are scored VG.

Top breeders and herds

Two breeders are tied for their performance in breeding top PLI females; the Dennison family from Denmire and the Eastash herd from Devon, each having seven females make the list. Six out of the seven from

Denmire are Maries

(the other being Denmire Goldwyn Kay) while the seven from the Eastash herd represent members of the Nellie, Nora, Yasmin, Lynn, Jean and Becky families. The list is dominated by Northern Irish herds as the Ballycairn and Laurelhill herds both have four females making the top 50, while Sperrin and Relough have bred three females each on the list. Within the 29 herds represented in the top 50, only two other herds, Dodleston and Lagangreen, have two females in the list with all other breeders having single representation.

Leading Constituents

Amongst living animals, the highest milk index belongs to Champion daughter Sperrin CC Ivory GP81 at 1372 kg. She is closely followed by four other females

exceeding 1300 kg, namely Townhouse Principal Angel 6, Acecroft Goldwyn Lila Z, Laurelhill Principal N Fay and Riverdane PS Sara. Sperrin CC Ivory has completed

two lactations and gave 17,239 kg at 4.0% fat and 3.17% protein in her second record.

Heavyweights in the butterfat index department are the Ivory’s from Sperrin, securing the top four spots ahead of Ballycairn Garter Tinnie. Leader is Sperrin Champion Ivory VG87 with 74.4 kg, which helped her secure second place on the top 50 PLI; she leads her dam and two full sisters. In butterfat percentage terms, the Eastash herd comes to the fore with their trait leader coming in the form of Eastash Breakout Lynn 10 VG85 who has now completed two lactations at 5.23% fat and 4.96% fat respectively. When considering protein, the Fay family at Laurelhill has the edge over the Sperrin Ivorys, with top spot currently held by the Netherside Dynamo daughter Laurelhill Dynamo Fay VG86 at 43.1 kg protein ahead of her stablemate and dam Laurelhill Principal N Fay VG86 at 41.9 kg protein, while the milk leader Sperrin CC Ivory is good for third place. With a +0.23% protein, top 10 PLI female Warnelview Goldwyn Ruby 2 VG87 leads the protein percentage list before the fat percent leader Eastash Breakout Lynn 10 VG85.
