WS2 SYSTEM
Paul Lubout
CONTENT
1.
Genetic inheritance similar to livestock
2.
DNA not the magic solution.
Can be used for:
3.
4.
•
Identification
•
Parentage
•
Origin – Mitochondrial (female)
•
Single gene trait selection
•
SNP – whole genome, 700k, 54k 10k
Wildlife database
•
Pedigree
•
Phenotype
•
Single genes – colour
•
Multiple gene traits - horn length
Genomics
WS2 DATABASE SYSTEM
WHAT YOU ALREADY
DO

You already have the following within the
group:
 micro chip
 ear tags
 DNA profiles
 Horn measurements

A historic data can be used
WS2 DATABASE SYSTEM
PEDIGREE
1.
Why ? How did YOU know what bull bred the best:
• “Piet”,
• “Madala”
• or “Charlie”
2.
You will not know it until you have parentage
Is the Dam important – YES - she contributes 50%
3.
Pedigree certificate
4.
Inbreeding - minimize

OBJECTIVE MEASUREMENT
PROF JAN BONSMA:
“OM TE MEET IS OM TE WEET”
thus
IF YOU MEASURE YOU KNOW
YOU ARE CORRCT IN YOUR
ASSESMENT
Average Horn Growth by Bull
2010 born calves
NAME
MADALA
GROWTH
(MM/DAY)
0.91
CHARLIE
0.95
PIET
0.96
Average Horn Growth by Bull
2011 born calves
NAME
MADALA
GROWTH
(MM/DAY)
1.046 (1)
CHARLIE
0.956(3)
PIET
0.963 (5)
SELECTION INDEX (SA)



You measure all the animals on a specific date born within 45 days
You calculate the average of all animals
You then calculate the selection index
(animals own value – average value) X 100
average value




Animals above 100 above average
Animals below average below 100
Work out average for different bulls
Accuracy 45 -50%
WHAT IS an EBV?
Prediction of genetic value of an animal
for e.g. Horn Length
 Based on:
 Animals own performance
 Animals relatives performance
 Relationship between traits
“ Is the best prediction of an animals
genetic value” (80% accuracy)

THE NEXT STEP –WS2
BUILD ON SUCCSES

You already DO following:






micro chip
ear tags
DNA profiles
Horn measurements
Historic data gives you a competitive advantage over persons
starting today without any information
Even if you start today you can have benefits within 12 months and
you can within a few years have full benefit of WS2 system
