Re: Cloning
Cloning has been discussed here before Peter, with many views, be prepared for a bumpy ride!!
Personally I don't agree with it, both on Ethical and commercial grounds.
Ethically, I don't believe we should be trying to manipulate creation in this way.
Commercially, while it may be good for a few breeders to sell clones of 'popular' show winners, there are bound to be detrimental effects on dairy farming as a whole.
Besides all that, where is the 'breed progress' in cloning an existing animal, it's like hitting the pause button, I'd rather watch the rest of the movie thanks

Re: Cloning
I used to be strongly opposed to cloning, but now support it. The breed could have been bettered by the genetics of great cows that were lost. Now with cloning, we can have those genetics back in a short period of time.

Re: Cloning
Just to add to that, the trend of cloning show winners will continue. Why would anybody clone a high index cow? There would be little profit to be made by it. By the time the clone is born, matures, and gets its own index, it will already be behind in the fast paced numbers game. Show cows, on the other hand, won't get run out as fast. Cows can compete on the show circuit for many years before the breed improves beyond them. Therefore, in theory, their clones will still be able to compete in the ring. This was proven by the Liz and Paradise clones.

I was discussing this fact with somebody recently, and then we were asking ourselves the question: doesn't this environment start in the uterus? You could also apply this to ET work: would the quality of the uterine environment of the recip already have an influence on how the animal will look like later and her performance?
I have a curiousity about this Gerbrich. Have often wondered whether anyone has ever done any comparisons between the results of ET dairy progeny, born from dairy or beefX recipients.
How much influence does the suitability of the recipient have on the mature progeny?
Likewise, I guess that it is possible that some outstanding specimens provide only a mediocre growing environment for their natural pregnancy. Therefore having a negative effect on family development.
Are these effects marginal? Can they be compensated for during the rearing period?
9 months in the womb, 2 years,3 months rearing. Is 25% of our outcome already decided the day that the calf is born?
