If you do not own/lease an equine you might just want to skip this post. Or read it and be glad that you do not have to administer wormings to 1,000lbs animals who generally don't really like a tube being put in their mouth and something squirted in.
The following has been my worming schedule for the past 4 years:
Jan or Feb
March or April
May or June
July or Aug
Sept or Aug
Ivermectin (Binectriin or 1/8% generic Ivermectin)
Nov or Dec
Every two months they are wormed with something. It seems to be working fine but I am curious as to others. What worming schedule do you follow for your horses?
