If I recall
correctly, some time ago UC Davis Vet School did a little study in which they
made an incision (it looked like a big slice) in the back of several horses
upper rear legs. They tried all sorts of different meds on these horses, some
they covered, some uncovered, and some they just hosed with plain water a
couple of times a day and did no other treatment. Big surprise, the horses
that were hosed regularly healed up better than anyone. Just keep that wound
clean, scrub the proud flesh and scabs out of it with a soft brush daily and
hose, hose, hose.
They had
pictures of these horses and these were not little cuts, they were gory
looking. Was it in Practical Horseman?
