I'm sure Tiz will answer, but I have to say I wouldn't use a billy that was used on untested females, (ie owner requesting I produced certificate before the mating I would presume s/he would have asked others). Male should be tested as well, and have a certificate, for the sake of any future visiting females.
I had to have my cerificate faxed down from SAC, as useless vet hasn't sent it through, (sent the bill though), before my 160 round trip with the 2 girls to a pedigree Togg, and now 160 mile trip to pick them up tonight.
If every goat was tested before mating we could wipe this horrible disease out. I believe it's rife in America (and europe?), but the BGS advice and responsible goatkeepers have managed to keep it down here. (I THINK I read somewhere about 5% of the goat population could be infected)
Check out British Goat Society website.
Sorry if anyone takes this personaly, but I believe if all goatkeepers pulled together on this we could stop this disease in its tracks and we would all save time and money not having to get our goats tested.
Actually just checked on BGS website (under 'health')
hope it's OK to copy this bit - Heading was something about How Widespread?
Very low - less than 3% of all goats tested*. Due exclusively to self imposed controls and self-regulating measures introduced by British goat keepers to avoid the spread of infection without any government aid or EEC grants. The British Goat Society and its members have been foremost in waging war on the CAE virus and continue to do so today.
