Re:


When a cow is (for example) EX-5E, that means she was classified Excellent and then after the next 4 calvings, she was deemed to still be EX. They can't move down, but the multiple Excellents indicate her longevity.

I think the second part of your question is American based where you sometimes see a cow listed at EX-91 (EEVEE) or something like that. I can't remember the order of the traits but that's the breakdown for their 5 major components of their classification system. I think it's Front End & Capacity, Dairy Strength, Rump, Feet & Legs and Udder - but someone may correct me on that. In my example, her rump score would be Very Good, where the rest of her breakdown is Excellent.

Re: classification system


She is excellent, she's been scored excellent 2 times, she also has received 53 stars in the breeds brood cow awards.

Brood cow status is based on how well progeny are doing. On the Aussie system I know its based off things like progeny classification & production.

53 is a very high amount of stars for brood cow award. Between zero and 10 is the more common amount in a normal cows lifetime.

High demand flush cows that breed on well get extraordinary amounts of stars.

Another note. Star brood cow status may be just 53* or 53SBC... or may be other versions I've missed...

Re: classification system


Yes that is correct. I believe an "E" is also still counted when a cow goes up every time ex 90,91,92,93,94,95 etc she would be 6E to my understanding.and may stay at 95 and still earn more E's but may not be any better then last time. Some cows will go EX and then maybe drop her udder. This is why He's are there to show how good the cow stayed over time. Some cows are 9E, that really impressive to stay EX at that age. Hope this helps, maybe I confused you...

Re: classification system


Once a cow is a certain age and excellent every couple
calves she can be up for an E when the classifier comes
so she will be scored again and see if she is still considered ex.

Re: classification system


I don't believe so. We just classified and I was going
to ask our classifier but forgot completely. We have
7 or 8 older cows that are ex and not any of them were
up for an E

Re: classification system


No, in USA only get E after 3 years. If a cow scores EX before she is six yrs. old she would be up for a "E" when 9,12,15.I think this is right, my memory gets foggy sometimes!!
