So...I have about had it up to here with the current stress level in the barn right now (you all cannot see how high I am holding my hand right now, but believe me, it's up there, lol). Between complicated calvings, a neighbor calling animal control on us because she's a moron, a sheep who refuses to stay in the fence, a daredevil bull who loves to climb stuff and jump off (threw himself off the s*** ramp yesterday and cut his leg open), now my two shetland broodmares, Janey and Pokey are dropping weight like crazy. Fecals say there is no parasite load but they sure look it. They get free choice hay and 16% grain 3x day right now. They somehow got lice this spring so...needless to say, they look like absolute crap right now. Their teeth have just been done and were not bad, I do sand purges since they're turned out on sand and I have begun adding oil to the grain because, basically...I'm out of ideas. So, I was thinking, maybe it won't hurt to deworm again anyway, the problem is, they are not cool with us near their faces, shots are okay surprisingly, but it takes like, 3 big guys to get an oral dewormer anywhere bear their faces and usually, they spit most of it out. I have been using the safeguard pellets since they will eat those, but I would love to treat with ivermectin. I dont think its going to happen orally. My question : can topical 1% cattle ivermectin be used on horses? I have heard horror stories about chemical burns and rashes on horses with pour-ons and abscesses and neurological reactions with injectible, but I would like to hear about other's experience, thoughts, suggestions etc. Put a call into the vet who is leary of over treating with clean fecals (totally understandable) but I wonder if just because eggs weren't found, doesn't mean worms are not a problem. I guess more than anything, I'm just curious about the use of liquid ivermectin in ponies. I have also read of people using the injectable orally (wouldn't help me in this case) but really I'm just curious. If I understand it correctly, the pour on is topical use only while the injectable can also be given orally?
