This is The easiest wormer I have ever used!! I have a mare I cannot use the tubes on and I cant even mix in feed... With this she eats it just like her feed. Works great all my horses look awesome!!!! It was recomended by a friend who breeds horses and uses it on his mares and foals. Nice bucket keeps it fresh and dry even in weather. Measuring cup is easy to read and use. Would and have recomended it to all my friends.
