White line dis­ease

Your Horse (UK) - - Your Horse's Care -

The white line is the area on the ground sur­face of the foot that ap­pears as a nar­row ring of horny tis­sue at the perime­ter of the sole. In­fec­tion oc­curs when this area is weak­ened and a cav­ity de­vel­ops, sep­a­rat­ing the outer hoof wall from the lam­i­nae, al­low­ing bac­te­ria to en­ter. Clin­i­cal signs: Widen­ing of the white line, dis­coloura­tion, lame­ness, sen­si­tiv­ity to hoof testers and pus from the coro­nary band. Causes: Ex­ces­sively wet con­di­tions, long spells of dry weather/be­ing sta­bled, poor qual­ity horn due to nu­tri­tional de­fi­ciency, bac­te­rial in­fec­tion and pen­e­tra­tion of the white line by sharp ob­jects. Treat­ment: Rest, clean­ing and trim­ming to re­store cor­rect bal­ance, re­moval of dis­eased tis­sue, drain­ing of any pus and im­prov­ing diet. Pre­ven­tion: Keep feet clean. Avoid rid­ing on overly hard go­ing or leav­ing your horse stand­ing for long pe­ri­ods on wet or muddy ground. from hoof testers. Causes: Pen­e­tra­tion of the sole or white line by grit or dirt, which re­sults in in­fec­tion. A hoof that is con­stantly wet will be­come softer, mak­ing it eas­ier for bac­te­ria to en­ter. Treat­ment: The ab­scess needs to be drained by a vet or far­rier. This of­ten brings im­me­di­ate re­lief. The hoof and area should then be thor­oughly cleaned and soaked in Ep­som salts to draw out the re­main­ing in­fec­tion. The hole should be ir­ri­gated with an ox­i­diz­ing agent such as hy­dro­gen per­ox­ide to re­duce fur­ther in­fec­tion. A poul­tice ap­plied overnight for three days will help drain the ab­scess and keep it clean. Plug the hole with cotton wool soaked in io­dine to keep the area clean and pre­vent re­in­fec­tion. An­tibi­otics can also be given. Pre­ven­tion: Pick out hooves ev­ery day and keep the hoof as clean and dry as pos­si­ble.
