Dairy Chitchat 4, an udder new thread.

Ancestry and visual assessment more reliable- from looking at the back pedigree it’s far more accurate at predicting future performance regardless of the bull used- we’ve genotypes for years and when you cross reference the results it becomes clear that you can’t make a silk purse out of a sows ear-

Very frustrating when the offspring of your better cows turn out poor, often despite getting the best bull available.

There’s a reason throughout the history of breeding, great cow families were so sought after.

It’s great in principle but when you actually sit down and correlate the data years later it’s very disappointing- if you remember I put up a load of them on twitter and was looking for a reply from icbf- I even sent them an email to which I’m still waiting a reply on- reality is nobody likes reality cause it’s much easier to chase a dream

Great output.

And then also there are good strong cow families that no matter what bull you use within reason you will get a good one.

Yes we have some with about 15 years. Imported the seed stock from north Italy near the Austrian border. Try to keep them purebred but up till 3 years ago they were running with the Holsteins and when the bulls were left out we had some crossbreds. We now run them as seperate herds on two different farms. I love their temprement and they go on forever. The crossbreds are the best cows we milk. They would calve an elephant for you. The only downside to them is they have a longer gestation.

Serious output- you must have cows doing 800-900 kg ms- why haven’t you bulls in Ai when your production is so good??

im not breeding for type- I’m breeding for an efficient cow who can deliver 10000 and 3.9% protein

unfortunately the Irish bulls that were 120-150 milk sub index when we used them turn out to be below 50 when they become daughter proven- that there shows that genotyping doesn’t work

if genotyping works so well why are there so few daughter proven bulls

I think this bull sums up the whole genomic system - read the advertisement- the sire that ticks all the boxes

But zsr is a proven bull and older than sew- he’s also an international bull which strengthens my case even more

Did you check his udder composite and temprament.
