It's not perfect, but it's an easy to follow rotational deworming system that covers MOST of the bases.

I did use this same worming rotation until I found out that it isnt as effective as you would think.. Studies have shown that by using a rotational wormer like this, dont work.. You are using a bunch of drugs without really knowing how effective they are. The better more efficent way to worm now is by getting a Fecal egg count done and then worming based on those results..

Article I found on it-
