In-Depth Information
Another common problem with horses that stand in dirty, wet footing is the condition
called thrush. Thrush is a decomposition of hoof tissues that usually starts in the clefts of
the frog. Anaerobic bacteria, those that survive and flourish without air and are present al-
most everywhere on the farm, are sealed in the clefts of the frog by mud and manure and
are kept moist by urine and muddy conditions. The bacteria destroy the hoof tissue and
produce a foul-smelling black residue that you will never forget once you have smelled it.
Erosion in the clefts of the frog can become so extreme as to reach sensitive tissue and
cause lameness.
One of the best ways to preserve your horse's hooves is to keep them clean and dry.
Hazardous Substances
Guarding your horse against chemical poisoning is essential, because horses like to invest-
igate unknown things by nibbling and tasting.
All toxic substances must be stored in tight, well-labeled containers. This includes rodent
poison, insecticides, herbicides, and antifreeze. Although lead-based paints are no longer
sold, you might find them on older horse buildings or fences, and horses should be pre-
vented from contact with them. Be sure to read all product labels thoroughly and follow
directions carefully. Any unlabeled substance should be discarded in a safe manner.
Chemical poisoning can often occur unknowingly. Don't feed treated grain or seeds that
were meant for planting, or you may be giving your horse a dose of mercury! Although
treated grains often have a pink or reddish hue, sometimes they look just like feed grain.
