You know, while feeding my horse the other day, I thought of the whole scoop size thing. Yes, we all have different sizes of scoops that we have or have not weighed/measured accurately. Some people mentioned that even using the same size of scoop, we might feed different amounts. My coffee can is completely full, your coffee can is 3/4 full, his coffee can is "mostly" full... If I don't use a full "scoop" size, I draw a line with a marker, but if its a bit over or a bit under, I don't care. Even my "one cup" of oats for my mare is anywhere from 1 acutal, measured cup to almost 2 cups. There are lines on my scoop, but meh - even *I* don't stick to it. If I scoop it and it comes up over a cup, then she gets over a cup that day.
What I wonder is, in the grand scheme of things - just how much does this matter? Last week, my friend told me to give a scoop of feed to her mare. So I dipped the scoop, came up full and fed it to her. The scoop is about 4 cups. If we both use a full scoop of the same scoop - just how far out can we really be and how much does 1/4 or 1/2 cup difference matter to an 1100 lb animal?
I can see an effect on special situations, or special very intensive feeds, but generally???
