Calves become exposed to their mother’s gut flora during birth and while nursing in the first few days after birth. One source:

Then the population will gradually adapt as the baby moves from milk to grazing, but rumens aren’t unique— this process happens (and must happen!) in every animal. We all have massive intricate communities of micro-organisms inside us and all over us! And they’re usually easily acquired from our environment and our families, because the world isn’t sterile. And they all undergo adaptation and adjustment if we change our diet or other variables in our living situation.

Try a search for the keyword “microbiome” to go down a rabbit-hole of information in whichever species you are interested in!

It's a most fascinating topic. The relationship between us and our gut bacteria affects mood, personality, health … the so far single most fascinating fact about the gut biome is that we've learned that the vagus nerve carries an overwhelming amount of information to the brain, rather than from the brain down.

yep, also a lot of serotonin is created in the gut so having proper gut health should help

"I contain multitudes" by Ed Yong is also a great book on the subject. It does get pretty heavy but summarizes the big picture of our evolution with microbes. He often compares the microbiome to a new frontier.

Here's a good synopsis of the book https://www.theguardian.com/science/occams-corner/2016/aug/25/lifes-little-surprises-i-contain-multitudes-ed-yong

Ooooh thank you! I've been getting really interested in the human gut biome and how it effects mood, metal and physical health and even intelligence. I will definitely be checking this out! Would this be better read or could one listen to the audiobook at work, in your opinion?

I did the audiobook. There is quite a bit of science jargon in a lot of places, so sometimes I missed out on absorbing that well by not seeing the letters. But I am a visual learner mostly anyway for that type of stuff. But I got the big picture and it was very fascinating. Was my morning commute audiobook for a few weeks.

A good friend of mine often says jocularly, "I am in the majority!" Maybe I should give him that book for his next birthday? :)

Now you'll think twice about eating that preservative riddled tv dinner.

Thats also why you get the shits after taking antibiotics
