So lately I have been hearing more and more about continuous dewormer in horse feeds. SmartPak, Pfizer, and Farnam all have it, as do many other large companies. I have always wormed my horses 4 times a year with tube wormers, and have never had a problem with them.
Which do you think is better/more effective? Some people say that quarterly is better, some say daily/continuous wormer, and some use both together. Any thoughts on this?
