I would say the strong smell is caused by the vitamin cotent rather than the protien. Kinda like the strong smell that urine has when you take strong vitamins. Just as an example: just notice the smell some of your urine after eating a bowl of cereal like cheerios or corn flakes, because cereal is mostly vitamins and crunchy air. If it weren't for the added vitamins in it, cereal wouldn't be very nutritious anyway. Just very moving yaknow what I mean.
Calf-manna is a good thing to be giving them ol' gals this time of the year esp. for molters.
