Outstanding longevity, with a particularly high rating for feet
and legs, has helped new sire Jardin achieve an impressive Profitable
Lifetime Index (PLI) of £81 and third place on entry to
the latest herd life proof rankings.

lifetime value characteristics of the new third ranked
£PLI sire Jardin.

The German-proven Jocko Besne son combines 478kg of milk and +47.5kg
combined fat and protein (including a top ranking +24.6kg for protein)
to add good production performance to his very sound commercial
type traits.
Jardin is available from the new online company Bullsemen.com and,
according to managing director Nick Kirby, represents outstanding
value.
“Jardin’s tall daughters show great potential for development
and have outstanding firmly attached udders,” he says. “A
composite score of +2.00 for feet and legs is also a good indication
of longevity, which means great lifetime value.”
Jardin is available through the www.bullsemen.com website at a
special online price of £19 per straw.

Note:
PLI - Profitable Life Index (PLI) is a very similar economic index
to PIN, but it recognises that milk production is not the only
factor to influence profitability, but that herd life also has
an important part to play. The core of its formula is the same
as PIN, but added to this is a weighting for lifespan. The lifespan
itself is measured either directly, or - in the case of younger
animals - predicted from certain type traits. The type traits
with the strongest association with lifespan are leg and foot
composite, mammary composite and somatic cell count. Locomotion
will be used where available for UK tested sires to replace leg
and foot composites.
