With heifers my first aim is to have a live calf, tend to use a lot of AA or easy calving LM like ZAG on heifers. Any heifers with a bit of age to them i might be a little more adventurous. In or around the 4-5% CD for heifers is fine for me.

I am daft but does breed matter for you guys? It’s a 6% cd Charolais a greater risk than a 6% lim, sim or otherwise?

Oh Jesus I think there world's apart. Both easy calved alright. Fiston is the easiest calved ch bull I've ever used. Allot of um fall out like small dogs. And start growing from day 1. The fiston calves bring a far superior shape and are carrying allot more muscle by 6months.

So the % only means so much? Still breed dependent?

% means 6 out of every 100 were a hard calving. Thats the same with a charolais or angus.

I'd assume 99%of charlaois ai bulls are used on mature cows so if they were used on heifers the likes of fistons calving difficulty could rise alot higher in the percentages as the heifers would struggle to calf them an awful lot more .

Right ok. So CD therefore is a different test for every bull. One bull could have a cd of 1% having been recorded only over mature big cows. While another could have a score of 10% after having been recorded on heifers or small cows. Without knowing the cows then is it of much value?

There's some truth in that, but ICBF do take the age and breed of cow into account. Also teh number of previous calvings the cow had (first & second parity etc). You can see all this data on their site. They list also the % breakdown of the dams for all the calvings recorded. What they don't know though is the size of the cow. For example would farmers tend to use a char bull only on big Lim cows, while only using a Lim bull on the smaller Lim cows. If all the cows were weighed, this would help things.
They can only work with what data they have.

Yea Char gave me a bit of information on the other thread if you saw it. That does make it much more valuable. It is a serious study if you think about it over thousands of dams. I was looking at the book wondering how the hell a culard charolais bull could have a lower CD than a PT bull etc. Not so bad I only made a fool of myself on here rather than in the yard arguing with an ai man. I'm not 100% happy with ai performance this last number of years so I'm better having my facts right!
