YES AND NO ,
recorded performance data with regard to sheep , i feel ,is as subject to interpretation ,as showing is , most performance figures by the individual sire reference schemes have a serious flaw in that most figures are more to do with the individual farmers feeding regime and his merchant ,(fatness can be adjusted for figures by feeding say more undegradable protien ) than actual performance off of unimproved pasture found on many sheep farms .We had our own recording scheme 20 years ago produced by one of the top army computer programers at the time and lambs reared with the aid of creep (sometimes fed only ad lib creep) are different animals than ones that perform off grass only .
i took this up with the MLC years ago but their reply was that there is not enough difference between animals on a pure grass diet , my reply was you just need to keep looking for the one that IS and use him, but there is no money in that for them trying to run a scheme .so they wernt interested .
The beef / pig schemes are relevent in that the recorded animals offspring are reared commercially on the same, similar diet as the adults data comes from .
The show ring also has its flaws in that `show type' sheep are very different to commercial animals they should aspire to , Big rangy , large boned rams that need masses of feed to get condition on them might look good on the day , but would be hopeless crossed with a suffolk mule ewe , you just end up with masses of 60kg store lambs you struggle to finish
I have always felt terminal sire ram lamb classes at the premier shows should be restricted to animals in a commercial weight range say upto 50kg , so at least we have half an idea as to what lambs they will produce conformation wise , I have been privilided to judge at some of these shows and i,m affraid a lean 90kg ram lamb does no one any good .
also lets get the adult sheep sheared , say a week or so before every show so we can see the animal and his / her fat and conformation not the immacuate trimming out .We could learn a lot from the usa 4H system
Showing can be a good advert , but it needs a damn good shake up , as at present and in the past it has done more harm than good .
