Yeah, and that’s not very helpful.
What that tells me is that in 1lb of it (if you have a larger horse and are feeding 4 4oz scoops) gives you:
lysine: 18gm
methionine: 6.35gm
fat: 9gm
So, back to the cost breakdown. Tri-Amino is 53 scoops. Let’s say you pay full price at $17.95 with, I think, $7-ish shipping - $24.95 so we’ll use $25. That’s $.47 per scoop, which is 10gm lysine and 5gm methionine.
The Progressive product is rounded) $45 for the 15lb bucket, which we already determined was, at the above level, 15 days. That’s $3/scoop.
You can double the Tri-Amino to get 20gm lysine and 10gm methionine (more than the PN product) and still be less than $1 (unless the shipping is way more than $7, but you can figure that out).
So, your choice
I bet you can add a fat supplement for less than $2/day
