JERSEY SIRES CATALOGUE
Spring 2008
Semen available from the Jersey Cattle Society
Lirsk – limited supply
A small quantity of DJ Lirsk semen has been released from stock by Viking Genetics
(the successor to Dansire following its amalgamation with the Swedish farmers’ cattle
breeding organisation). DJ Lirsk was a superb sire. A Lemvig son with Oda Heino
as maternal grand-dam.
Lirsk’s January 08 proof is:
137 milk; +.37% butterfat; +.17% protein; 199 PLI; 40 PIN; -6 scc; +.2 LS; 1.2
PTAT
His Danish figures rate him as:
101 Body (incl 109 chest width); 111 F&L; 118 Mammary; Milking Speed 104;
Temperament 106; Daughter Fertility 97.
List price £17, while stocks last.
Sexed makes sense
The demand for Jersey cattle showing no signs of abating – just
look at the list of new members we welcome to the Society.
And farmhouse cheesemakers, in particular, have cottoned-on
to the benefits they gain from including 25 – 30 per
cent Jersey milk in their production.
Conception rates from sexed semen have hit 70 per cent on
maiden heifers in one South-eastern Jersey herd.
All round the reports indicate that sexed achieves results
close to conventional AI in maiden and once-calved heifers.
As more farmers house heifers until after first cut silage-making,
the AI season can be extended without excessive work.
At £35 – 48 per straw, 90 per cent heifer births
will look a cheap price to pay compared with freshly-calved
heifers at £1350 at auction.
Jersey Sires – packing protein
With the increasing emphasis being placed on milk protein
by milk processors, it is pleasing to note that the Society’s ‘Jersey
Sires’ is well to the fore in the Top 20 available Jerseys,
for both weight of protein and protein percentage production.
