I do breed Texel's but have found tups with the lower ebv indexes to be less susceptible to worm competed to those who have high ebv indexes. I have used two high indexed tup with "good" fec ebv that no matter what wormer I tried from the vet never shifted them but that is the biggest problem with the breed they are concentrating on the genetics more than trying help with research into making the breed more resistant to worms but I'm going to look at starting to do a more in depth fec analysis with my vet
Oh well...to wrap this thread up the poor OP doesnt know which way to turn after receiving all this `advice`!
Texels with lots of FEC recording = www.baber.co.uk (or the NZ tex breeders I think )I really would disregard any FEC ebv's in any animals that haven't been FEC tested themselves, or at least from a population where a lot had been tested. The accuracy of those ebv's will be so low as to be meaningless. Any that do have data going into the analysis will have the waters mudddied by the ebv's calculated purely on the basis that high growth rate means low worm resistance, and vice versa.

I'm pretty sure FEC EBVs are calculated independently and with no reference to any other production trait
Until recently Fat was public enemy number one, causing blocked arteries that would kill you, then suddenly, sugar is the devil's work, and fat is good!! (Booming butter and cream sales)Reading these kind of threads and a lot of other stuff folk say, makes me realise just how clueless so many farmers are.
It's science, it's fact. So whether you agree with it or not is inconsequential!!!
I tend to agree but woe betide you for having an opinion (and having the temerity to voice it) that is different to some others on here!Until recently Fat was public enemy number one, causing blocked arteries that would kill you, then suddenly, sugar is the devil's work, and fat is good!!

I think we should take everything on board and make decisions on our own circumstances. ...I've read a NZ consultant saying that FEC's are not that useful, as they don't tell you how many worms are in lambs, just how many eggs they are laying...and we all know NZ is always right [emoji6]
The thing is it was the same opinion plenty of farmers (and vets) used to have, but has now been shown to be flawed and result in an accelerated build up of worm resistance to wormers. I'm not sure why you are so reluctant to accept this, and so happy to continue along your current path. When you realise you have multiple resistance you will regret you didn't take action sooner.I tend to agree but woe betide you for having an opinion (and having the temerity to voice it) that is different to some others on here!
