when fiber is listed as a percentage of ingredient on protein feed is that basically just filler?

If molasses is used as an attractant is that also considered filler?

Bottom line question is this: if you have two protein mixtures side by side and one has an attractant and the other does not I assume the deer will eat more of the one with molasses. But are you accomplishing your goal if what they are eating has more filler than the non molasses protein?

Feeds have minimums and maximums on the label that are required to be there and guaranteed by the manufacturer. So a couple of pounds of molasses might be there as a taste only but it factors into the protein level and fiber %'s on the label. It does not effect what the animal still gets from the feed IMO. Then end result is what the animal gets from that bag of feed at the end of the day. A test of the feed will show you that.
