Breedingofraregameandrarecolouredgame
The breeding of rare game such as sable and rare coloured game species such as golden wildebeest and black impala has
becomebigbusiness.Theselectivebreedingofsuchgameishoweveroftenfrownedupon,asitisseeminglyonlydonetomake
money,withlittleornoconservationvalue.However,asthisindustryisindeedverylucrative,incomegeneratedinthiswaycan
be ploughed back into numerous conservation projects and is a very welcome addition to the maintenance budget of game
farmsandnaturereserves,whostruggletomakealivingfromtourismalone.Whatisimportanttokeepinmindhowever,are
the ethical matters regarding breeding of game in general. As rare coloured animals occur as a result of mutant genes that
spontaneouslyappearandwhich arethenselectivelybred,careshouldbetakenthatthesemutantgenesdonot escapeinto
wildpopulations,assuchhumanmanipulatedstockcouldhaveaverynegativeeffectonwildpopulations(rememberthatsuch
mutantgeneswouldinmostcasesnotsurviveundernaturalcircumstances).Theseanimalsshouldthusberegardedassemidomesticated animals and not part of the wild population. The breeding of rare species such as roan and sable in captivityis
altogetheranothersituationhowever,andthebreedingoftheserarespeciescouldactuallyassistintheoverallconservationof
theseanimals.

may carry the disease for long periods, becoming emaciated and eventually succumbing to predation. Tuberculosis has had a
devastating effect on wild buffalo herds, crossing the species barrier and widely contaminating predators, scavengers and

ThehistoryoftheGoldenWildebeest(asseenontheGoldenBreeders’website)
GoldenWildebeestnaturallyoccurredalongtheLimpopoRiverbasin,adjacenttotheTuli-BlockofBotswana.Earlyfarmersin
the1920s,calledthem“VosWildebeest”.
ThefirstGoldenWildebeestbullwascapturedbyAlecRoughintheearly1990sonthegamefarmSwinburne,intheLimpopo
Valley. This is the area from which the majority of Golden Wildebeest originate. They formed an integral part of the large
migratoryherdsthatoncemovedfreelybetweenSouthAfricaandBotswana.
Very few people are aware of the phenomenal amount of work that was done to get Golden Wildebeest to where they are
today.GoldenWildebeestwerefirstreferredtoas“RedorYellowWildebeest”bypioneerbreeders.Thedecisiontochangethe
nameofthesecolourvariantswasasadirectresultoffalseaccusationsofcross-breedingbetweenblackandbluewildebeest.
Wildebeest hybrids (Black and Blue Wildebeest Crossbreeds) were also referred to as red wildebeest by nature conservation
officials. Due to extensive DNA sampling and research done by Dr. Antoinette Kotze, we could clearly show that no black
wildebeestgenesoccurredamongstanyofourwildebeestherds.
BydisprovingthisaccusationBarryYork(foundingmemberofGoldenBreeders)decidedtodistancehimselffromanyfurther
confusionandfoundedthename“GoldenWildebeest”.Thisnamewassoonadoptedbyallinthewildlifeindustry.
