The latest official notification of an outbreak of RVF near Kimberley makes it necessary for farmers to decide what to do. It is risky to leave sheep, goats and cattle unvaccinated since large-scale losses and especially abortions may follow. Nobody can be sure of future weather or predict with confidence how next summer's rains may cause large scale or severe outbreaks, but if everyone waits until such outbreaks occur before vaccinating, there may be large scale losses since OBP (which makes the vaccine) will be overwhelmed by an avalanche of orders and vaccines will therefore be very scarce. Remember that preparing and testing vaccines is a long and exacting process, and cannot be suddenly scaled up to millions of doses.
To lower the risk, all non-pregnant ruminant livestock should be vaccinated in the coming winter. For longer term security, vaccinate all breeding replacement livestock before breeding each year as a minimum measure, since it is likely that in most cases effective immunity will be lifelong.
Farmers are strongly advised to contact their local veterinarian to decide on the risks, the correct vaccines to use, and the best vaccination schedule for their farm. Do not use unregistered products that claim to be vaccines, they are illegal.

UITBRAKE VAN SLENKDALKOORS
Die NWKV het kennis geneem van die uitbraak van Slenkdalkoors in die Vrystaat en is bekommerd oor die impak wat dit op die kleinveebedryf en veral woluitvoere mag hê.
Dr. Claudia Cordel, ‘n veearts van Execuvet wat Slenkdalnavorsing doen as deel van ‘n span internasionale kundiges, maan produsente in die omgewing van die uitbraak om dringend hul diere met dooie entstof te ent om kudde teen die uitbraak te beskerm.
Produsente word versoek om met hul plaaslike veeartse te skakel vir professionele advies om hul kuddes teen die siekte te beskerm.
The NWGA has taken note of the outbreak of Rift Valley Fever in the Free State and is concerned on the impact it may have on the small stock industry and especially wool exports.
Dr. Claudia Cordel, a veterinarian from Execuvet who conducts research on Rift Valley Fever as part of a team of international experts, is urging farmers in the vicinity of the outbreak, to vaccinate their animals urgently with inactivated vaccine to protect their flock from the disease.
Producers are advised to contact their local veterinarians for professional advice in order to protect their flock from the disease.
RIFT VALLEY FEVER AGAIN
VOORKOMENDE INENTING KAN UITBRAKE KEER
Dr. George de Kock, Cape Wools SA (CWSA) Slenkdalkoors Werkgroep het verslag opgestel waar Slenkdalkoors identifiseer word as 'n risiko vir volhoubare ekonomiese wolproduksie.
Voorlegging soos gemaak tydens 2018 NWKV Nasionale Kongres
Inentingsprogram vir Slenkdal, deur Dr. George de Kock :
Basiese beginsels
1. Winter inenting - nie onderhandelbaar !
2. Nie dragtige ooie - lewendige Smithburn entstof
3. Voor-uitbraak entstof - 5X meer effektief
4. Enkel-naald entstof gedurende uitbraak
5. Dragtige ooie - 2X geiaktiveerde enstof
Huidige aanbevelings
1. ENT nou !!!!
2. Alle nie-dragtige diere met Smithburn
3. Dragtige diere - wag tot na afloop van lam en daarna met Smithburn
4. Daardie distrikte wie geaffekteer was deur 2010-11 uitbrake, herhaal Smithburn in die Lente vir nie-dragtige ooie
5. Alle ooi lammers met Smithburn op 3 maande ouderdom, en "booster" 3 maande later.
6. Leeftyd koste = R2 per ooi per jaar !
KRITIES DAT BOERE NOU SLENKDALENSTOF BESTEL !
Mnr. Leon de Beer, hoofbestuurder van die NWKV rig ‘n ernstige, dog dringende versoek aan boere om onmiddelik bestellings vir Slenkdalentstof by kooperasies te plaas sodat Onderstepoort Biologiese Produkte (OBP) ‘n aanduiding kan kry van die behoefte na entsof en gevolglik betyds voldoende entstof kan vervaardig. Veeatse maan dat Slenkdalkoorsuitbrake in die komende seisoen verwag kan word.
