> modern breeding can select for heifers with ~90% confidence

May you expend on this? I know we kinda have selection techniques for eggs to crush them before hatch but I guess that’s not what’s happening with milk caws as the diary is the main target and the cow need to give birth to start lactation. Or perhaps it’s the impregnating technique or some hormone therapy that tricks the odds?

> in this day of age of high-priced beef, even if you get the occasional bull you're not exactly complaining either.

I depends on the breed: in this days of high volume diary and meat consumption, most of what people eat comes from specialised breeds that hare very good at producing milk OR muscle. The non-desired sexed are not so valuable. Switzerland (and others countries I can’t remembers) recently passed a calves handling low to require farmers caring them for a minimum days in response to industrial sloped into unethical territories.

That documentary shows another practice in India : some invaluable calve are just roped to a fence and forget until dehydration. https://christspiracy.com

Huh? A holstein bull calf is selling for around $3,000 right now. That's... insane.

I remember from what doesn't seem all that long ago when fats didn't even fetch half that much. Beef has gone wild. If that's not valuable, what do you consider valuable?

I’m not sure we’re talking about the same data. Here’s the price evolution of lived calves in EU. They happen to be very high since 2025 (300€/500€ for diary/meat) but if you click « select all » on the top left you can see they use to be around 100€/200€ in the previous 10 years, going as low as 60€/head during covid.

> what do you consider valuable

Fair point, I didn’t express it well: I don't think calves “have no value” in general, they’re sentient beings. However, as you pointed out and shown ahead, they are also part of a market and in some places their value is not high enough to care them well [0]. Some of them happen to be euthanized very shortly after birth:

> In one survey of Canadian farmers, an average of 19% of calves were euthanised at birth and of those respondents that euthanised calves, 34% reported using blunt force trauma (sharp blow from a solid object to the head) [1]

There’s also the "bob veal" (2–3 days to 1 month) [2], I guess the goal is to have a different taste but I’m not sure about that.

side note: I found the technique used to "select for heifers" you mentioned: the process is called flow cytometer and it sorts the sperm with a laser.

For the sake of understanding our communication breakdown, what suggests "in this day of age of high-priced beef" is talking about 5-10 years ago?

[aziaziazi]

To have a better understanding, one could suggest to search for the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize

[9rx]

Exactly. From my point of view the strongest plausible interpretation of "in this day of age of high-priced beef" is that it recognizes that the current situation is a historical anomaly.

But that isn't how it was interpreted. We saw the weakest plausible interpretation + silly criticism transpire instead. However, I trust in good faith that it wasn't intentionally interpreted in the weakest way, but rather that it simply failed to communicate its intent.

Which is where I seek an understanding of where it broke down so that I can be clearer in the future.

[aziaziazi]

Indeed I didn’t read "in this day of age of high-priced beef" as a few month (or 1-2 years) situation for beef only and more like "in this days of inflation", like since a few decades.

The communication breakdown also comes from me as we are two in the thread. I should probably re-read "How to Win Friends and Influence People", a best seller that truly changed my relation to others 15 years ago.
