Seems as tho when any issue comes up, I recommend dietary evaluation! But on my own behalf : )… diet, overall, has a 90% influence over….. well.. everything!
I have a TB/Appy cross mare, now 17 yo, that would abscess on a regular basis as a younger lass. Had one bout of colic with her as well. Over the course of a few years and to try to keep her weight consistent (air fern), I decided to try to limit the amount of sugar she was getting and put her on a no added sugar diet: no cookies other than sugar-free, one carrot, she won’t eat apples. She is most consistent on TC Senior. To my surprise, her abscess action all but evaporated. She has not had one in over 8 years now. It is possible that 1) she grew out of the metabolic state that left her susceptible, and/or 2) the minimization of sugars in her diet helped. Take a closer look at the ingredients of your boy’s grains, make sure ratios of Calcium and phosphs are correct, that there is iron, selenium and biotin in proper amounts as well. A hoof supplement might be indicated here or maybe even just a good all-around vitamin.
I treat all abscesses with a magna gel/paste slather, a couple Pampers and a boot (unless they are truly deep and stubborn, then I soak before slathering). My farrier will NOT core them out, thank you!! I have yet to see any lameness after 48 -72 hours (10 opportunities to learn and apply over 8 year span so far, 4 different horse involved, one is Lyme-related and this even works for HIM! Vet, farrier and I are assuming it is a low grade bacterial die-off pooling in his feet). The key for us here is to keep the resulting hole clean until it closes again. Vet-wrap is my all-time best friend along with duct tape and a Cavallo boot : )
Recurring abscesses imply a metabolic or systemic involvement. I apologize for being redundant but evaluate your horse’s diet as well as the environment (always clean your hoofpick BETWEEN feet as well as after, and have a separate pick for each horse) and equipment that you use. As already mentioned, keep hooves UTD and standing areas clean.
Good luck with this, I would be interested in hearing of how you choose to go forward with this and the results. I make only the loosest correlation between sugars and abscesses and am open to any and all info that supports or defies this theory.
Afterthoughts: what type of ground are you jumping on, how often, how is he shod/trimmed, does he have thin soles, could this all be impact-related?
Sure there's right and wrong but mostly there's just a whole lotta different.
