Rav Schachter concern is not specific to DA intervention but rather sit his on slaughtered dairy cows.... That also has serious issues with the metzius.... Namely, they're slaughtered at the end of their milking life because....they're no longer giving (sufficient) milk. How does that reflect on the cows still in the milking cycle and what are the proportions of cows in at the end of their cycle vs the beginning?
See Seder Chalav treifah for an in depth limud of the relevant metzius and halacha specifically focusing on DA and DA intervention.

We know that this isn't a reliable source for anything.

[imayid2]

It is a statistical impossibility that there isn’t more that 2% of what we’d generally consider חלב טריפה in our milk irrespective of the DA question.

Based on?

Based on?

The amount of טריפות גמורות in every shlachthoiz

When did they become treifos? Are they treated the same as milk cows? If they are milk cows then

You are claiming that cows only become treif immediately before slaughter? On what basis? Makes no sense.

.25/ (Age of cow slaughtered - age of cow start milking)

I chose .25 assuming the traifa happened in the last 3 months you can substitute it for .125  .5 or 1 or whatever number you feel like.
number i found for US (quick googling) is start milking at 3 slaughtered at about 7 so,

.25/(7-3)=1/16 or 1 out of 16

1. Chazaka
2. More become treifos as time goes on

You are claiming they are all treifos their whole life? On what basis? Makes no sense.

There is no chazaka that there is less than 2% treifos.
At any given time that animals are shechted there are well over 2% treifos. Thus it is a statistical impossibility to pretend that there is less than 2% treif in your milk which is from hundreds of cows.

Each cow has a chazaka.
You don't seem to be understanding statistics well.

Keep in mind that even the 2% are only because we do not pasken about some of the cases and if we would there would would be fewer.

Among hundreds of cows there is a ודאי that there are over 2% טריפות גמורות. This is basic statistics if you are aware of the amount of ודאי טריפות every slaughterhouse has. You don’t seem to be aware of the numbers.

Since when are halachos based on statistics?

Then what is your heter to drink milk if there isn't shishim against the chalav treifus in your opinion?

[imayid2]

Since when are halachos based on statistics?

It is a אנן סהדי or call it whatever you like. It’s a ודאי. There are many similar instances in Rishonim/poskim

[imayid2]

You are assuming there is a heter 

[EliJelly]

You are assuming there is a heter 

I'm assuming you won't drink without an heter. And no, I'm not assuming that you like Rav Shachter don't drink milk.

[Definitions2]

What does DA stand for?

By that reasoning almost every miut sheino matzui product will have a big problem. Take a vat of green beans that hypothetically have a תולעת in one out of every 200 serving sizes (picking a product and percent out of a hat). מיעוט שאינו מצוי כלל. Yet when the product is processed in a vat containing 5,000 servings it is a statistical וודאי that there is a בריה in the vat which is not בטל . Therefore everything should have to be discarded. I don’t know of any heter to take a pot that וודאי has a בריה mixed in and separate it into multiple portions to make each portion a safek and therefore kosher….

Rabbi Dovid Cohen (CRC Chicago) has a very interesting write up about it. Suggests that because the animals have babies and trieifos cannot, therefore obviously many treifos aren’t really treifos. We just don’t know which ones.

If you sample check 600 servings from the vat and find 3 insects, the entire vat becomes assur? What about a tanker? What about an entire greenhouse?
