I would like to ask the teachers about the ratio of pig dung, who can tell me?
Is there such a saying?
How come I haven't heard of it-it's actually an indicator of feed digestibility! -- the fat pig said, how much dung can he pull if he eats a kilo of food? what does this index mean? Why use this index?-- reflect the digestibility of feed-- eating + drinking water = pig heat production + fecal production + wet urine + weight gain- -- ask how many kilograms 0.75 cubic meters are-- hehe I don't understand, but there is this indicator, and I don't know how to calculate it. In study. -- it seems that there is still no sensible person.
