Vat grown meat

[Hallucigenia]

Yes but,… more females than males must be kept to maintain breeding stock. So it’s likely the (overwhelming) majority of males and only some of the females are killed off young for human consumption. So I would suggest the majority of steak is male.

Ain't necessarily so. It is possible to send females for slaughter after calving, as long as you give them a bit of time to recover from pregnancy and the farmer pays close attention to body condition. So-called once-bred heifers (OBH) aren't popular in the UK but AIUI are more so in countries where cattle are primarily grown for meat and not dairy.

However here it is reasonably common to put a dairy mother to an Angus bull or similar. The father's genetics give you meat quality that may not be as good as a pure-bred "meat" animal, but is good enough for the steaks you see in supermarkets and chain restaurants. The dairy mother needs a pregnancy for lactation, and you're not "wasting" any female beef animals on pregancy.

This is what Churchill wrote in 1931:

Even without the new sources of power great improvements are probable here. Microbes, which at present convert the nitrogen of the air into the proteins by which animals live, will be fostered and made to work under controlled conditions, just as yeast is now. New strains of microbes will be developed and made to do a great deal of our chemistry for us. With a greater knowledge of what are called hormones, i.e. the chemical messengers in our blood, it will be possible to control growth. We shall escape the absurdity of growing a whole chicken in order to eat the breast or wing, by growing these parts separately under a suitable medium. Synthetic food will, of course, also be used in the future.
