In 1982 het ’n vriend van Peter (CP) Massmann, ene Don Vanimann
(destyds die VSA se Simmental-bestuurder), die gedagte van ’n Simbra-ras met Massmann bespreek tydens ’n Wêreldfederasie-vergadering. Massmann het die gedagte verder bespreek met Willie Angus,
Kwaab Johnstone en Gerd Olschewski en hulle het die wiel amptelik
aan die rol gesit. ’n Maklike paadjie was dit beslis nie gewees nie, en om
’n Suid-Afrikaanse boer te oortuig van iets nuuts en vars, anders as dit
waaraan hy gewoond is, is ’n byna onbegonne taak. Daar was verskeie
wetlike aspekte wat eers bespreek moes word, toestemming om die
Simmentaler Genootskap se grondwet te wysig moes verkry word en
talle ander uitdagings moes die hoof gebied word.

Gelukkig het die manne aan die stuur van sake die nodige insig en
visie gehad om te glo hulle sal daartoe kan bydra om ’n produk te vestig wat ’n positiewe bydrae tot die Suider-Afrikaanse beesbedryf sal
kan lewer en hulle het volhard in hul strewe. Dit het daartoe gelei dat
die Simbra amptelik as ’n ontwikkelende ras verklaar is met ’n kennisgewing in dié verband wat in die Staatskoerant (no. 11063) op 11 Desember 1987 gepubliseer is.
Die Simbra-ras het sedertdien gevorder tot 32 698 vroulike diere en
217 telers – waarlik iets om te vier en ’n bewys van die ras se sukses.
Intussen is die ras tot ’n ontwikkelde ras verklaar, soos gepubliseer in
die Staatskoerant (no. R. 935) op 2 Oktober 2009. In 2012 sal die Simbra amptelik sy 25ste bestaansjaar vier.

Dr Arnold Olivier’s Chairman Report
“Management meetings were held on a regular basis with the Simbra Marketing Plan as
the main aim and objective. Earliers this year
discussions were held with Johan Potgieter,
General Manager of the Simmentaler-Simbra
Breeders’ Society in South Africa, to finalise
the framework that will serve as a working
document and be updated regularly. The
Marketing Plan is an important tool to ensure that Simbra breeders stay competitive
in an ever-challenging marketing environment where we need to compete with other
breeds,” Dr Arnold Olivier, Simbra Chairman
in Namibia, said in his annual report. Other
Simbra office bearers are Diethelm Metzger
(Vice-chairman), Michelle Adkins (Secretary),
and additional members Mike Wiechmann,
Jaco Labuschagne and Werner Wilckens.
According to Dr Olivier’s chairman report the participation by Simbra breeders

• Tydens die 2010 Internasionale Simbra Kampioenskappe op Vryburg is 254 Simbras deur
24 vertoners ingeskryf. Te midde van ’n verbod op die beweging van diere oor die land
se grense as gevolg van die uitbreek van
slenkdalkoors is ’n suksesvolle internasio­

• Getrou aan hul aard het die Namibiese telers
ook nie op hulle laat wag nie. Wolfaard Aring
vertoon die bul Makam Majestix (A9020B),
wat later net as Stix bekend gestaan het, by
die Windhoek Skou, en Stix word aangewys
as die Namibiese Grootkampioen Simbrabul.
• In 1994 word die eerste Internasionale Simbra Kampioenskap in Suidelike Afrika in Pretoria aangebied, en Stix word aangewys as
die eerste Internasionale Groot Kampioen
Simbra bul.
• Stix was die eerste Simbra KI-bul by Taurus
en meer as 1 000 kalwers van hom is aangemeld. Van sy nageslag het dan ook verskeie
skoue gewen.
• Skoue het bygedra tot die bekendstelling van
hierdie diere en op daardie manier kon telers
bewus word van hul genetiese potensiaal.
• Dit beklemtoon ook weer eens die waarde
van die wisselwerking tussen Namibiese en
Suid-Afrikaanse telers

Die Simbra is nie net ’n ras wat hoogs aanpasbaar is nie, maar kan ook gedy in omstandighede wat wissel van uiters ekstensief tot intensief in die voerkraal-opset. Hy beskik ook oor
’n uitstekende geaardheid en temperament.
Namibiese Kampioene
Die eerste internasionale grootkampioen­
bul, Makan Stix A90 208, het aan ’n Nami­
biese teler behoort. Hy was die Windhoek
Skou se nasionale Simbra-grootkampioen­
bul voordat hy in 1994 internasionele roem
verwerf het op die eerste Internasionale
Simbra Kampioenskap in Suidelike Afri­
ka wat in Pretoria aangebied is. Stix was
ook die eerste Simbra KI-bul by Taurus en
meer as 1 000 kalwers van hom is aange­
meld waarvan heelwat skouwenners ge­
word het.

Daar is in hierdie stadium baie belangstelling
en navrae in hierdie verband van telers en
belangstellendes vanuit die buiteland en ons
gaan die geleentheid gebruik om ’n waardige
vertoonvenster vir die Simbra in Suidelike Afrika te wees.
• Sprekers van formaat sal gebruik word, wat
nuwe tendense kan toelig en relevante Simbra-aangeleenthede kan bespreek ten einde
die Simbra se pad vorentoe te help bepaal.
• Sprekers wat meer lig kan werp op die eise
wat aan die moderne vleisprodusent ge­
stel word – plaaslik sowel as internasio­naal
– sal optree.
• Erkenning sal gegee word aan die Simbrapio­niers en -stigters in Suidelike Afrika.

The new Simbra Rand Value Indices
S i m b r a
Thys Meyer and Johan Potgieter
One of the goals of the Simmentaler/Simbra
Cattle Breeders’ Society of Southern Africa is
to improve the profitability of beef production
through proper sire selection and genetic improvement. To increase profitability through genetic selection our first objective is to identify
those traits that directly influence the income
and/or cost of production. Producers therefore
have to anticipate and research what the demands and needs of the market will be in 3 to
5 years from now.
Once a producer has identified these needs
and the economic relevant traits that he will
have to select for, a considerable number of
breeding values to be considered remain. Assuming that multiple traits will need simultaneous improvement an objective method for
determining relative importance and economic value of each trait is needed to ease the selection process. That is exactly what the Simmentaler/Simbra Cattle Breeders’ Society of
Southern Africa did in close collaboration with
BREEDPLAN. Since May 2011 Simbra breeders
and commercial customers have had the luxury to select sires that will maximise profitability under different production systems by making use of a single rand value index.
Hazel developed the concept of total (aggregate) merit which represents the total monetary value of an animal in a given production
system due to the genetic potential of that individual. Henderson reported that the same
aggregate value could be calculated through
weighting breeding values by their relative economic value. These breeding values, weighted
by their relative economic values, are summed
to produce the total (aggregate) value for each
individual. The estimation of the relative economic values requires detailed economic information on the production system. Because
costs of production change from producer to
producer, these economic values also change
from producer to producer.
The new Rand Value Indices allow Simbra
breeders and their commercial customers to
select sires that maximise profit under different production situations. The difference in
the rand value of the index expresses the difference in profit potential.
The Rand Value Indices available to Simbra breeders and commercial customers are:

• Simbra Self Replacing Weaner Index (SRW)
• Namibian Self Replacing Grassfed Index
(NamGF)
Simbra Self Replacing Feedlot Index: The
Simbra Self Replacing Feedlot Index is aimed at
a production system in which calves are weaned
at 7 months. Steers are fed extra rations for 120
days and are slaughtered at around 11 months
and 410 kg live weight. The Feedlot Index
predominantly emphasises calving ease and
fertility as well as 400-day growth (red graph).
The economically relevant traits (blue graph)
emphasised are Cow Weaning Rate and Sale
Weight (at 11 months of age). This is followed
by the Cow Survival Rate with the carcass traits
following. Consistent longer- term application
of the index should result in hardy and fertile
animals with a high calf-to-cow weaning ratio
and acceptable carcass characteristics.
Namibian Self Replacing
Grassfed Index (NamGF)
The Namibian Self Replacing Grassfed Index is
aimed at a production system where calves are
weaned at 7 months and then kept on natural
veld to be slaughtered at around 28 months
and 470 kg steer live weight. The Namibian
Self Replacing Grassfed Index predominantly emphasises fertility, growth (600-day) and

ry Committee decided that the Simbra will
not compete with Bos Taurus as a terminal
crossbreed, which led to the exclusion of
the Terminal Sire Index.
Dr Olivier’s Chairman Report

Other activities Dr Olivier highlighted in his report included a threeday Simbra course on the farm of Katja and Diethelm Metzger in the
Seeis area. The course was presented by Fred Dell who was assisted by
cattle judges Sigi von Luttwitz and Lourens Swart. The first day started off with various lectures on the theory of cattle breeding, management, judging and the use of modern technology in breeding. This was
followed by a practical demonstration. The following two and a half
days were utilised for students to do their own evaluations and judging before they were evaluated by the examiners. Twenty-three people from all walks of life participated and six were promoted to candidate senior judges.

July 2011
Last but not least, Simbra breeders experienced a lovely “breeders’
visit” to the farm of Dagmar and Werner Wilckens in the Osire area.
The day started off with a lecture on the critical areas of feeding during the growth phase of stud animals by Christo du Plessis from Feedmaster. This showed how important and beneficial feed input during
the growth of an animal is. Erica Wiechmann then explained the use of
the mating predictor as a selection tool, which was well received. Most
of the day was spent looking at animals with parallel in-depth discussions on various breeding and management systems by Willie Grobler,
Technical Breed Advisor.
The Simbra Breed is here to stay and with the past wonderful rainy
season it will certainly grow from strength to strength.

The economically relevant traits (blue graph)
emphasised are Cow Weaning Rate and Sale

Consistent longer-term application of the index

animals with good carcass characteristics for
this type of production system.
er bulls should still consider individual calving
ease and birth weight EBVs.
Owners of herds wishing to maximise genetic progress using these indices must record
calving ease (direct and maternal) and birth
weights, 200- and 400-day weights, scrotum
size, ultrasound scans, days-to-calving and mature cow weights. While mature cow weights are
not used in the index directly, they are affected by days-to-calving, 400-day weight and fat.
In Rand Value Index selection it is very important to measure as many of the component
EBVs as reasonably possible. Limited recording of traits may result in poor selection decisions of future breeding animals. As with all
indices, producers should use the Rand Value
Index to rank potential replacement animals,
consider the individual EBVs of those animals
in terms of their own breeding objectives,
and select those animals with individual EBVs
meeting these breeding objectives. Selection
should also consider non-EBV characteristics
of the animal such as functionality, structure
and temperament.
The selection of breeding animals has become burdened with information overload.
Currently, genetic evaluations (EBVs) are produced for many production, reproduction and
carcass traits, with more to become available
in the future. It is not easy to identify the most
desirable and profitable animals from such an
array of raw information. A well-formulated genetic selection index is the best approach to
summarising EBVs in a way that leads to optimum economic improvement.

Simbra
Kuddebestuur op Ondekaremba-Nord
S i m b r a
Werner en Dagmar Wilckens het in 2000 die
plaas Ondekaremba-Nord by sy ouers oorgeneem waar daar suksesvol met die Simmentaler en Brahman gekruis is.
“In 2007 het ons besef ons maak geen vorde­
ring meer nie. Ons het van Willie Grobler se konsultantediens gebruik gemaak en hy het voorge­
stel ons moet Simbra-bulle gebruik. In 2007 het
ons die Ondeka Simbra Stoet geregi­streer om
waarde toe te voeg tot ons diere.”
Werner en Dagmar boer op twee aangren­
sende plase wat in totaal 10 000 ha beslaan. Die
bestokking is 1 bees per 10 ha, die gemiddelde
reënval die afgelope 10 jaar was 413 mm en die
aantal vroulike diere staan op 345 waarvan 260
geregistreerde Simbras is.
Met 3 000 ha ontboste veld en ’n stygende
dieregetal het die weidingkwaliteit en die massa aansienlik verbeter. Dus is hulle besig om die
bestokking aansienlik te verhoog. Die gemiddelde TKP wissel tussen 402 en 412 dae die afgelope vyf jaar.
Die kuddebestuurstelsel wat die Wilckense
volg, behels die volgende:
• Alle koeie kalf sedert 2006 by die huis nadat
klein huiskampies geskep is.
• Die agt klein huiskampies van 20 tot 30
ha bring mee dat die speenpersentasie
opgeskuif het van 75% na 90%.
• Meer wins word gegenereer omdat meer
kal­wers aankom (15 kalwers per 100 koeie).
• Verliese word beperk deur effektiewe
waarneming (ongediertes, gate, moeilike
kalwings, dooie geboortes, spene, baarmoeder-ontsteking vir herbesetting).
• Alle kalwers en koeie word by geboorte
geweeg en koeie word ingeënt met MultiMin, Vitamien A (droë seisoen) en die verpligte
inentings.
• Kalwers word op 6 weke geëvalueer. Swak
manlike kalwers word gekastreer.
• Die evaluering van die voorkoms van die jong
kalf, gespeende kalf en sy gewig, koei­tipe
en koeigewigte help om besluite te neem
oor paring.
• Koeie en kalwers (tussen 6 en 10 weke oud)
word na die bulle by die poste verskuif
waar hulle bly tot en met speen of dragtigheidsondersoeke, wat twee keer per jaar gedoen word.

kalwers op dieselfde dag gebore word, word
een se geboortedatum met ’n dag aangeskuif.
Die letter van die vader word eerste as hoofletter geplaas, bv. E, daarna volg die letter van die
moeder se vader, bv. r (kleinletter) en dan die
geboortedatum, bv. Er 2-1-6 (gebore op 6 Janu­
arie 2002) op die oorplaatjie, soos in die voorbeeld op tabel aangedui word.

Almal ken die gesegde: penny wise and pound foolish. Miskien is dit ’n
goeie beskrywing van boere se filosofie agter bulkoop. Boerdery is ’n
besigheid waarin winsgrense klein is en ’n boer planne moet maak
om soveel moontlik geld te bespaar om te kan oorleef. ’n Vervoerkontrakteur het eenkeer gesê: “Boere soek alles verniet en dan soek hulle
daarby nog afslag ook.” Menige keer wanneer bulkopers redekawel oor
pryse van bulle het ek al aan dié vervoerkontrakteur se woorde gedink.
As jy vir ’n boer sou vra waarheen hy op pad is met sy boerdery en
hy weet nie, vra hom net waar sy bulle loop. Wys hom sy bulle en sê vir

hom: “Hier is die toekomskaart van jou kudde.” Die vinnigste manier
waarop ’n kudde geneties vordering kan maak, is deur die regte bulle
aan te skaf. Dit is algemeen bekend dat 50% van die gene in die kudde kom van die laaste bul wat gebruik is, 75% van die laaste twee bulle
en 87.5% van die laaste drie bulle. Die toekoms van jou kudde is dus in
die hande van jou bulle.
Naas ’n boer se grond, is sy beeste sekerlik sy grootste bate. Konserwatief bereken is die waarde van 500 teelkoeie sowat N$5 000 000. Indien jy 500 teelkoeie het en jy gebruik 40 koeie per bul, dan het jy 13
bulle nodig. Indien jy goeie kwaliteit bulle aanskaf en jy betaal N$30
000 per bul, gaan jou bulle jou N$390 000 kos. Dit is baie geld om aanvanklik uit te gee, maar indien jy in ’n siklus kom om elke jaar drie bulle
te vervang raak die bedrag heelwat kleiner. Dan kan jy die drie ouer
bulle laat slag vir N$10 000 elk wat jou weer N$30 000 in die sak gaan
bring. Dit beteken dat jy net N$60 000 per jaar aan bulle hoef te be­stee.
Ek weet N$60 000 krap jy nie agter ’n bos uit nie, maar onthou net dat
die besluit oor bul koop ook een is wat jy neem wat jou N$5 000 000
se belegging meer of minder gaan maak.
Die ander faktor wat geweldig belangrik is, is die gebruik van teelwaardes om meer geld in jou sak te sit. Indien jy selekteer vir bulle met
’n teelwaarde wat net +6 kilogram bo die rasgemiddeld is vir 200 dae,
behoort jy 3 kg per kalf swaarder te speen, want 50% van die massa
word deur die bul bepaal. Indien jy jaarliks 400 kalwers verkoop en jy
speen kalwers wat 3 kg swaarder is, produseer jy 1 200 kg meer vleis.
Teen N$20/kg is dit reeds N$24 000 in jou sak. Teelwaardes kan jou ook
help om die probleem van kalwingsgemak te verminder. Tien dooie
kalwers is N$40 000.
Aangesien die resessie ons almal in ’n wurggreep het, is dit elke boer
se versoeking om sy eie goedkoop steek-osse te gebruik. In dié tyd is dit
miskien goed om te onthou wat ’n ou vriend van my gesê het, naamlik: “My pa het my geleer as ek kunsmis en bulle gaan koop moet ek nie
suinig wees nie.” Koop goeie bulle en vermeerder die waarde van jou
beeskudde. Moenie penny wise and pound foolish wees nie.

Balancing growth, carcass and fertility
S i m b r a
in your breeding programme
The increasing focus on “customer requirements” presents
a major challenge for modern beef producers. While
backgrounders, finishers, feedlotters and processors
continue to push for faster growing cattle with improved carcass yield and quality there is an ongoing need to maintain on-farm productivity
in the commercial breeding herds. Continued
selection pressure will be required to maintain
and improve reproductive performance, maternal ability and cow efficiency.
Fortunately, breeders have access to BREEDPLAN Estimated Breeding Values (EBVs) for a range
of traits of importance to each segment of the beef
supply chain. Through the careful use of EBVs, together with visual assessment of market suitability, maturity type and structural soundness, it is possible to achieve a
high probability of selecting the best animals to meet your particular production situation and customer requirements.
There are a number of important principles that you should consider when planning a balanced breeding programme. The first and most
important step, is to establish a clear set of breeding objectives for your
herd. This involves analysing the current performance of your herd and
comparing this with the anticipated requirements of your future customers and with your herd production targets. Once you have completed this exercise you will be well situated to specify the characteristics
required in replacement breeding stock to meet your breeding goals.

STEPS IN ESTABLISHING BALANCED
BREEDING OBJECTIVES
The worksheet used in the example can be used
to assist you in establishing suitable breeding
objectives for your herd. The steps required
to complete the worksheet are as follows:

Huidige stoetvaars:
Step 1. List the traits of economic importance
List only those traits of real economic importance to your customers and/or your
own herd’s future productivity. This should
include traits influencing herd reproductive
performance, growth and carcass traits. You
can also include “non‑BREEDPLAN” traits if you
believe that they are of real economic importance.
Step 2. List your customers’ requirements
Remember that “the breeding for today is already done”. Your breeding objectives should relate to your vision of likely future market demands in at least 3 to 5 years’ time. That is when the results of your current breeding decisions will be realised.
Obviously it is impossible to be definite about what the future will
bring. Nevertheless, careful analysis of market forecasts and trends in
consumer demand can provide some ”best-bet” insights into likely future customer requirements.
Due to the uncertainty of predicting future market opportunities it
is important that your breeding objectives are designed to ensure that
future generations of progeny have a high degree of versatility and the
ability to match a range of production and market situations.
The wide array of market specifications make it extremely difficult,
if not impossible to produce an animal which is ideal for all situations.
You should define a particular market as your primary target and focus
mainly in that direction. The golden rule to remember is that for maximum market versatility it is important to avoid extremes in any trait.
Step 3. List your future herd production targets
In order to optimise the use of the land and feed resources allocated
to your cattle enterprise it is important to set realistic targets for weaning rates, calving spread, turn-off age, etc.
This may require an investigation of the typical production levels
achieved by other producers in your region. Don’t be too conservative.
It is a good practice to set targets for your herd which are at least as
good as or better than average of the top 25% of herds in your region.

Step 4. List your herd’s current performance levels
This is often the most difficult step in many situations. It requires knowledge of your current herd production levels (e.g. weaning rates, percentage of difficult calvings, turn-off weights), as well as feedback from your
customers on the performance of your stock further along the production and marketing chain (e.g. growth rates during the backgrounding
and finishing phases, carcass yield and meat quality).
It is difficult to determine in what direction you should be shifting
your herd to achieve your future targets unless you have a good understanding of the base from where you are starting. If you haven’t
collected relevant production data and market feedback information,
now is probably a good time to start.
Step 5. List your breeding goals
By comparing your current performance levels with your future herd
production targets and future customers’ requirements you can identify those traits which need to be emphasised in your future selection
and bull purchase decisions.
For example, if your customer feedback indicates that your steers tend
to be too light with excessive fat cover, then maybe you need to select

bulls with greater growth potential and increased leanness. If your calving rates are less than optimal or your calving spread is too long, then
maybe you should place greater emphasis on female fertility and/or
reduce the milk production potential of your cows to give them a better chance of re-breeding early in the mating season.
Step 6. List your selection criteria
Once you have determined your breeding goals, the next step is to list
the relevant selection criteria that are available to assist in meeting these
goals. For most economically important traits EBVs are available to assist in ranking potential candidate animals for selection.

Not all economically important traits have objective measurements
available. Selection for structural soundness, temperament and “maturity pattern” still requires visual assessment and judgement.
When listing your selection criteria, remember that the more traits
you consider the less progress you are likely to make for any particular
trait. While single-trait selection is rarely an optimal breeding strategy it is just as important not to try to incorporate too many traits into
your selection programme. (The exception is where you make use of
a genetic selection index, e.g. Self Replacing Namibian Grassfed). It is
important that each selection criterion is related to a breeding goal
with real economic importance.

For example, if one of your breeding objectives is to reduce the incidence of dystocia (calving difficulties) in your herd, then relevant selection criteria include EBVs for Birth Weight and Calving Ease. If a breeding
goal is to increase retail beef yield, then relevant selection criteria include
EBVs for Eye Muscle Area, Fat Depth and Retail Beef Yield percentage.
Step 7. Prioritise the selection criteria
In most cases, there will be several traits identified as requiring some
emphasis in your breeding programme. Once you have identified the

portance. This will require some knowledge of the scope for genetic
improvement of the various traits, the genetic relationships between
traits (both favourable and antagonistic) and the relative economic importance of genetic improvement in each trait.
When determining priorities for selection it is important to distinguish between the benefits of achieving gains in your current herd from
those obtained from gains in future herd performance. The optimum
balance between reproduction, growth and carcass traits to maximise profitability from the current herd will differ from the optimum balance for future herd profitability.
For example, due to the economic importance of maximising the
number of live calves born, reproduction traits usually demand greater emphasis when considering culling strategies for the current herd.
However, after consideration of its low heritability and limited scope
for genetic change, fertility usually commands less emphasis in selection to improve future profitability.
Examples of establishing breeding objectives
The example below shows a completed worksheet used for establishing breeding objectives in a herd targeting the production of yearling
cattle suitable for the supermarket trade.
In the example it was determined that major emphasis should be
placed on increasing sale weights and carcass weights; with some emphasis also on improving finishing ability, heifer calving ease, female
fertility and reducing mature cow size. Again, relevant EBVs are available to assist in the selection of animals to improve these traits.
Establishing breeding objectives in a situation where the main market target is the production of yearling cattle suitable for the domestic supermarket trade.
