I've never seen bodybuilders taking antibiotics for size tho tho heard of plenty of steroid and protein/testosterone stuff.
But I know some chicken farmers in my neighborhood who double the chicken size with antibiotics.
Quite possibly. It will also bugger up your immune system maturation spectacularly. That doesn't matter so much for animals destined for the slaughterhouse, but it does for you because viruses aren't affected by antibiotics.
And that will indirectly influence our size?
Is there any pattern of size gain/growth in humans since we started using antibiotics on farm animals?
One thing always have been mysterious to me is that growth/size is attributed to nutrition/genes/workout but I know some villages (more like distant tribes with no connection to modern world) who practise old style farming and heading livestock without any modern methods and they've plenty to eat but still they've not gotten taller or bigger. They've sheeps, goats, chickens, plenty of fruits and grains in their diet, lots of physical work but no size gain.
And if the person from the same tribes comes to the US as a kid, you can see them get taller/bigger then their siblings back home. So it can't be their genetic limit.
But yes I think it would work.
A human with a borked digestive system will be incredible unfit.
Cows have a fundamentally different digestive tract, and I’m going to guess antibiotics suppress or eliminate cow digestive tract biota that are normally commensal but for whatever reason slow their growth, either by consuming nutrients or excreting signally molecules, or otherwise contributing to a cascade.
I similarly hypothesize that you could do a poop transfusion of skinny people with excellent metabolisms to aid in weight loss for fat people with terrible metabolisms.
In the meat industry, the current practicing of just mixing in antibiotics with the animal food by default is not sustainable. Cleaning up that industry is not going to be popular and very disruptive but also very necessary. A lot could be done with clear certifications and subsidies here.
Also, as a bonus, on whether existing resistant strains tend to lose their resistance if they're not kept on their toes with a steady supply of antibiotics.
This is terrifying and has far far worse implications than climate change. Imagine if we regress back to time where medical science is useless? - Where even having a child becomes a killer because the antibiotics don't work anymore.
I know most people aren't ready to give up meat, but we need to cut production massively and soon. Maybe cloned meat is the answer.
The magic cloned meat fairy should and may well never amount to more than a strange and precarious confusion, about our potential and desirable relationship to food and its environment in crisis.
We could start by eating way less meat, the amount that our ancestors ate more or less, and that doctors advice (once a week or so).
the normal ecology of bacteria is to produce toxins to compete with other bacteria and their gene passing across species is set up so that they gain resistance via exposure to new toxins..guess what the new toxins are?
Yes,, antibiotics..the same bacteria toxins re-repurpose and learn how to make artificially
