I'd like to ask all the teachers about the manure-to-feed ratio of pigs; can someone tell me?


--------------------------------------
Is there such a saying??
How come I've never heard of it
--------------------------------------
It's actually just an indicator of feed digestibility!
--------------------------------------
Take a fattening pig, for example: if it eats one jin of feed, roughly how much manure can it produce?
--------------------------------------
What problem can this indicator explain? Why use this indicator?
--------------------------------------
It reflects feed digestibility
--------------------------------------
Feed intake + water intake = pig heat production + manure production + urine moisture + meat growth
--------------------------------------
Let me ask, how many kg is 0.75 cubic
--------------------------------------
Hehe, I don't get it, but this indicator does exist, I just don't know how to calculate it. Learning.........
--------------------------------------
It seems there's still no one who understands~~~
