I own a horse who is a bit of a "hard keeper," and when I first purchased him, he was about 150 pounds underweight. I was feeding him a 12/8 complete pelleted feed (in addition to his pasture forage and hay), but I could still see ribs. A relative suggested I try a daily feed thru wormer. Within a month, he had gained weight and was very shiny and healthy. I have used this product with all of my horses ever since (in combination with paste worming with an ivermectin/praziquantel product twice per year--fall and spring). For anyone who is having trouble getting their horse to gain weight (after ruling out any medical issues), I highly recommend you try this product.

Pros: Very Effective

Cons: A little pricey

I think this is one of the better phsilim products out there.

Pros: Its easy to dispense

Cons: Expensive
