Breedplan – 30 years of taking the guess-work out of cattle breeding
Common-sense cattle breeding*
1. Be knowledgeable and use good information

The National Beef Recording Scheme (NBRS)
The National Beef Recording Scheme (NBRS)
1972 NBRS started (43 years). 1978 Bob Freer appointed as the first National Co-ordinator of the National Beef Recording Scheme Animal Genetic and Breeding Unit (AGBU) technical development Agricultural Business Research Institute (ABRI) commercialisation
Breedplan
1982 Simmental breed produces first set of EBVs 1985 Breedplan introduced – BLUP technology (30 years) (Breedplan Group Breedplan Breedplan International) 1990s Selection Indices using Breedobject software NSW Agriculture and major breed societies extension role 2005 SBTS and NBTS formed – Breedplan extension 2011 Genomic enhanced EBVs
Breedplan International – worlds most widely used genetic evaluation
system for beef cattle
Developed in Australia
Used by - 44 breeds
- 100 breed associations
- across 15 countries
Growth, carcase and fertility EBVs evaluated together in a multi trait model
Database of over 40 million animals
R and D budget A$20 million per year

Estimated Breeding Values (EBV)
EBV = (weight of individual – ave. weight of group)
x heritability
= (380 – 350) x 0.3
= 30 x 0.3
= +9 kg

Structural soundness
Genetic differences in animals that have a desirable structure score
Expressed as the percentage more progeny with the desirable score
Scored by accredited scorer on cattle less than 750 days of age
Front and rear feet angle: 1(SA) – 9(SH) Bull A +30 Bull B -50
40% more progeny with desirable feet angle

Common-sense cattle breeding*
1. Be knowledgeable and use good information
2. Take time to think
3. Be consistent
4. Keep it simple
5. Be patient

‘Long gone were the days when the only criteria in cattle selection were “beautiful” cattle and pedigrees. With the introduction of BREEDPLAN in Namibia a new technological “quantum leap” has been made and breeders who have been involved in weighing and taking measurements with reliable record keeping over longer periods are now rewarded.’ Mecki Schneider “Namibian Master Farmer of the Year for 2000”
