Ok, so Iíve never done a power pack on my horses and Iím thinking about doing 1 this year (after talking to my vet of course). I wanted to know opinions on how and when to do it? My boss raises TB racehorses, and she said to use just regular (25 gram) Panacur paste wormer 2 times a day for 3, 5, or 7 days. Now, I know that the actual Panacur Power Pack is 1 tube of 57 grams once a day for 5 daysÖwhich do you guys do? When do you guys feel is the best time to do a power pack when you are only doing it once a year?
