Performance

- Advancing Sire potential using measured genetic traits.
The only aspect of a sires performance that will influence its offspring, is its breeding (its genes).
S.I.L is used to provide the performance data required by our Clients.
For more info on S.I.L - see below

Survival

- Stock must live and survive a challenging Environment.
All stock must prove their worth in this difficult environment providing us with a natural selection process.

Questions -

• Should stud stock be grown in an easy un-challenging environment?

• Does a challenging environment breed superior animals?

S.I.L - The only aspect of a sires performance that will influence its offspring, is its breeding (its genes).

The best way to measure a sires genetic potential is to measure the individual traits together with its complete family history. For this intensive task we use the Sheep Improvement Ltd (S.I.L) Genetic Engine.

All Stud stock are performance recorded using S.I.L.
The main recorded trait groups are -

• Weaning Weight BV (WWTBV)

• Live Weight 8 BV (LW8BV)(Live weight at 8 months)

• Eye Muscle Area (EMABV)

• Lean Weight BV (LEANBV)

• Fat Weight BV (FATBV)

• Lamb Survival BV (SURBV)

From these trait groups, S.I.L creates several other groups

• Terminal Sire Overall (TSO)

• Terminal Sire Growth (with meat) (TSGm)

• Terminal Sire Meat (with growth) (TSMg)

• Terminal Sire Survival (TSS)

Frequently asked Questions about S.I.L

1. Why is this small ram rated more highly for growth than that large ram I want to buy? I’d never buy a small ram when growth of my lambs is so important.

2. I want to improve lambing percentage and I only buy twin-born rams. Someone told me this was wrong. How can a single-born ram be any good?
