100% agree with this.
And do you know what will happen ?
That milk will be creamier, and fattier, and richer, and taste
so much better.
Does it taste better because of the taste of the manure making its way though to your glass of milk ?
Nope. That's just crap.
The manure makes the soil rhizosphere happier and healthier because it is more diverse.
The more diverse soil makes the grass happier and healthier.
The healthier grass makes the cow happier and healthier.
The happier and healthier makes happier and healthier milk.
Diversity. Diversity. Diversity.
When there is a multiplex of life forms and individual microbe and bacteria and mycelial life, they all compete to keep each other in a dynamic balance of balanced population control.
I'll bet you that grazing fields supplemented with manure have more bugs, more complex topsoil, more mushrooms, more clover, more pollinator flowers, more insect life, more
everything.
And just about every one of those life forms will add their own little tweak to the end quality of the milk. Every little bit of micro piss and micro crap they push out is food for something else in the complex web.
Now
Can you imagine if some scientist in a lab coat analysed the equivalent
N : P : K elemental ratios for a cow's theoretical needs, and then fed the cow just that, through an intravenous drip ? That and that only ?
Now just imagine what that milk produced by that optimal (sic) diet would taste like.
