Importance of genetics
• Genetics is permanent and cumulative
Good genes introduced remain & are
built on
Bad genes introduced. . . !!
• Difficult / impossible for management to
compensate for bad genetics

• High Production Index rams with High accuracy %
• 4kgs extra weight at weaning
• Approx 2 weeks earlier
• Less labour input
• Less veterinary costs
• Less feed costs (grass/concentrates)
• Stronger ewe lambs
• Higher likelihood for ewe lambs to breed in 1st
season
Improved flock Genetics

• Maternal benefits far outweigh the benefits in lamb
growth performance
• Using rams of high Maternal Index will result in:
• Higher lambing %
• Less lambing difficulty
• Higher number of lambs reared to weaning
• Moderately sized ewes with high output
• High weight gain to 40 days – milk
Improved flock Genetics

Genetics
• The way in which an animal grows and develops is
influenced by a number of factors
• Feeding
• Disease
• Climate
• Management
• GENETICS
• Only this last element - genetics - is passed on to the next
generation.
• The Sheep Ireland genetic evaluations highlight the
animals with the best genetics.

• Approx one third of registered pedigree breeders now
participating.
• 33,766 Commercial sheep farmers (Dept of Agri –
census 2011).
• Approximate annual ram demand of 15-16,000 rams,
based on a breeding ewe population of 2.5 million.
• 2012 LambPlus recorded over 6,000 rams.
• Large number of non-pedigree sold annually.

What is the CPT?
•CPT – Central Progeny Test.
•Helps increase links. By increasing links we can increase
accuracies.
•2013 CPT Program:
•35 Rams
•7 Breeds
•2100 Ewes
•Laparascopic AI – 4 Flocks
•7 days

Why use Artificial Insemination?
• Allows us to identify the sire used 100% accurately
• Many different sires can be used
• Full control over use of rams – allowing us to maximise linkages
• Lambs born together under the same conditions
• Rams evaluated as fairly as possible
Benefits for Farmer
• Majority of lambing complete in 3-4 days
• Even bunches of lambing when it comes to drafting
Disadvantages of AI
• A lot of labour required at lambing
• Difficulties in poor weather
• Not economically viable on commercial scale

Option A – Weight Recording
• 50% of lambs – up to max of 100 lambs
• 2 weights
• Lambs need to be accurately identified in some way
• Tags recommended – management tags/NSIS
• Spray – Least favorable option
• Weights recorded on-line
• Group summary reports will be available to benchmark
performance

Option A – What benefit?
• Huge variation within every flock in terms of ewe & lamb
performance
• If farmers could identify poorer lambs & poorer
performing ewes – informed decisions could be made to
improve output
• Option A will allow farmers to benchmark their
performance against others

Option B – Maternal Flock Recording
• Recording necessary on minimum of 20 ewes required
• What is to be recorded
• Lambing – DOB, lambing difficulty, birth weight
• 40 day weight – between 30 & 60 days of age
• Weaning weight – approx 120 days of age
• Performance report generated by Sheep Ireland

• Again there is huge variation within every flock in terms of
ewe performance
• By identifying better performing ewes and in-turn their
lambs – progress can be made annually.
• Farmers can select replacements from:
• Twin lambing ewes
• Ewes that lamb with no interference
• Ewes that conceive to first service – fertility
• Ewes that rear lambs to slaughter weight at first draft
• Many other measurements can be maintained…………….

Option C – What benefit?
• Help to evaluate ram performance.
• Major differences are recorded between the progeny of
different rams.
• These differences are seldom/never identified.
• Some rams are profitable, some are problematic.
• Identification of lamb Sires will contribute hugely to the
Sheep Ireland €uroStar evaluations
• Hopefully leading to a commercial flock recording service
