Changes to Aussie indexes from APR to BPI HWI and TWI


Breaking this convo off from the Immunity + thread, mainly cause its probably my fault for the offtopic. emoticon

Info from ADHIS on the new indexes:

It's like our new type weighted index - If you have a multiple trait index where the bull ticks every other box exceedingly well even if they have a little less type, they will go higher on that index because they are so good for those other traits.

When will the new Australian indexes be used?

Next proof run is when they are launching.
We have two proofs runs a year April/August and a ABVi (interbull) update in December.

I do have some preliminary data with now the new indexes will look & how they compare to old. I may be able to show a little of how it stacks up - but only on current proven bulls.

Off topic side note, we are also looking at getting ADHIS to have another look at how some of the type stuff is calculated, and do things a bit better there too. i.e. as teat placement currently stands a bull on 99 is perceived to be horrible for that trait and a bull on 120 as great, the one on 99 though is far closer to the ideal than 120 - which you may end up struggling to get the cups on as her teats are too close. So we are working with them to display a lot of those intermediate traits differently (also in this category are things like leg set & pin set).

Will classifications link [sign in to see URL] [sign in to see URL] values? It seems the adhis and classification scores are not linked at all?



Can you clarify what you mean by not linked at all? HFAA do all the classification that goes into the type ABVs & Jersey house do most of the jerseys and reds.

So if we look at a well known Australian cow - Elmar Boss Jessica 3rd - [url][sign in to see URL]

Who has many classified daughters with her own class and ancestors with class. This should all be calculated into the ABV type score? They enter a (their best) production record.

Is this the case and ABRI have a hopeless website OR is it ignored?

The ABRI site is light years behind CDN and more recently Accelgen. It is actually holding back the potential flow and selling of genetics within Aus and exporting out. It is so hard to find animals you'r interested in. I'd go as far as saying it is holding the stud aspect back in Aus.

Re:


I would have a very educated guess and say that she's got 2 national ID's a lot of the times when people register cattle they don't realise that HFAA can give the cow a national ID when she already has one at the DPC (northern herd in this case) so that national ID is not linked to one sitting at ADHIS with all the production & pedigree etc records behind her.

This may not be the case, but the amount of times I've seen it when we have run genescreen on a herd, it's the most common cause of missing data.

It can be repaired if you get a data dump from the DPC and HFAA and then run them against each other back to swap the ID's over to the correct one (I can do this by the way!!).

We have repaired more than a few herds like this over the years. The main problem lies in that we do not, at this stage, have one central database - this is going to be done next year as far as I know.

SO really it's not ABRI's fault, it's a lack of both centralised data and audits... and probably who should be doing it. I mean, it's probably not our place to do it either, but we have made some people pretty happy too.

If you know a herd where the data isn't linking I can take a look and see what looks wrong. Will need a data release authority to do it but that can be arranged too.

P.s. It's not an official function of genescreen anymore, but not too hard for me to rig up a wee database at home and figure out what's gone wrong.
