Mud! Mud! Glorious Mud!

With yet another storm about to hit Britain, we have had the wettest winter since, well, forever! But what does all this rain mean for our horses?

I feel very lucky in that Otis’s field has minimal mud, so he and his friends have been happy all winter, with no concern about mud fever, tendon injury etc. Phoenix’s field isn’t so good, but even so it’s only pastern deep at the gateway. Some fields are knee deep in mud, and only last week I saw horses being evacuated from their field which was so submerged that only the top rail of fencing was visible!

So what problems are you likely to encounter with muddy fields? Firstly, the obvious problem of mud fever. Some horses are more susceptible to it than others, and once a horse has had mud fever they are more likely to get it again. How can you prevent mud fever? How long is a piece of string?

The bacteria involved in mud fever thrive on damp, warm conditions. For example, a muddy field! The best preventative is to avoid the muddy field, but this winter it is nigh on impossible. So drying the legs regularly, giving time off the mud is important. I don’t think horses with heavy feathering should have their legs clipped as it gives some protection, however if they develop mud fever it can be hard to treat with all the hair.

The next big problem that I’ve seen a lot of these last few months are field injuries. Either pulled tendons from the deep going, or slip injuries where a horse loses their footing and jars themselves, or they slide over in the field, or they do the splits. The injuries associated with slippery ground can affect the muscles of the back, hindquarters, shoulders or legs. Basically all over! In particular, the sacroiliac area is often damaged by horses slipping around, and pulling themselves through deep, heavy mud. The only real preventative is to avoid the deep going in the first place, but if you can’t then sectioning off the deepest area of the field, for example the gateway, so that at least the horses aren’t trotting or cantering through the deep mud. Checking legs daily for any signs of heat or swelling, and if your horse starts to behave abnormally (such as today’s client who fidgeted and fussed when I put the saddle on, and we believe he’s tweaked his back) then rest them and call the physiotherapist, chiropractor or whoever usually manipulates your horse. They will identify sore spots and be able to ease it if it’s been caught early enough, or refer to the vet for further diagnosis.

Some yards have stopped turn out completely for the moment, and it’s a hard balance to find between looking after the land and not wrecking it for spring, and ensuring the horses stay emotionally happy and healthy. I think it’s a balance between exercising horses sufficiently that they do not feel the need to gallop around their fields, so doing more damage to the land, and if they are staying in that day they they get out for a leg stretch at least twice. And not having miserable horses standing all day in the mud because if they’re standing there miserably, they might as well be standing in their stable! I’ve found that letting your horse guide you is the best; yesterday I rode first thing in the sleet and Phoenix didn’t seem overly keen to go out, so I gave her some hay and left her munching for an hour while I rode another horse, and likewise if she’s standing at the gate at 2pm there’s no point leaving her there for another 3 hours.

What can we learn from this winter for the future, in terms of your routine, or field management? Firstly it’s important to be critical of yourself: is your winter grazing the driest bit of land? And if not, change it! Winter grazing needs to have good drainage; it could be your most uphill piece of land, or have empty ditches on the perimeter to aid drainage. The type of grass also is important too, but I’m no expert on field management so I’ll leave that subject before I get in too deep. Could your gateways be improved? By laying hardcore if possible, or those grass mats. Is the gate in the best place? Can you use two gateways to reduce footfall and damage to the gateway and to reduce the likelihood of horses standing at the gateway expecting their next feed.

Next, it’s important to consider which horses you have in the paddock. Big horses, or heavy horses do more damage to the land because they sink down into the mud, so destabilising the land. Small, finer ponies do less damage, so they might be better in your field which doesn’t drain as well. The number of horses is also important to consider. There’s the guideline of one acre per horse, but this acre must be very fertile, have good grass and sward, and only have a 14.2hh grazing it. Who probably lives in overnight. Bigger horses need more space, and when there’s less grazing because of the time of year and the mud horses in general need more space. So if you have five acres, you don’t really want any more that two big horses in, or four small ponies in winter. The ratio may need to change in the spring and summer as ponies notoriously need less grass to avoid laminitis, in which case you might put those four ponies onto three acres, and those two big horses onto four acres. Roughly speaking anyway. The moral of the story is to have the ratio right for winter and adjust it accordingly in the summer, rather than have too many equines for your space in the winter.

I think everyone has some lessons to learn from this winter about preparing and managing their fields ready for next year, and we’ll all be busy come the spring repairing the damage to our winter paddocks; be it blown over fencing from the high winds, or the fact that fields more closely resemble a ploughed field than a grazing area. It’s been a tough winter for all horse owners, but we should try to take the problems of this year on board so that we can make improvements for next year.

A Muddy Problem 

Over the weekend I read and interesting article about an experiment on the prevention of Mud fever – See here.

There’s no scientific basis for the experiment, but I thought about it logically. Experts have said for years that continuously washing horses legs is a contributing factor to mud fever, and it is far better to let a horse stand in and then brush off the dry mud.

But what if the horse is standing in and their legs aren’t drying properly? Or if an owner has limited time to dry the legs properly – such as a heavily feathered horse, or they only coming in during the day. People advocate the use of towels, but I wonder how towels are dried and kept clean (numerous towels and a strict laundry cycle I guess). And also, does rubbing the legs to dry them rub dirt particles against sensitive, damp skin and cause minute wounds for the bacteria to enter? 

This article repeats the importance of not over washing legs, but said if necessary then it should be done but the focus of care should be rewarming the legs. I can see the inverse correlation between warming the legs and the time taken for them to dry, but I thought the bacteria liked warm moist conditions?

Lots of questions have been thrown up, and it’s so hard to know what to do in muddy conditions. Usually I don’t worry about mud fever and Otis, but this winter is so wet that I’m beginning to wonder how much wet and mud his legs can handle. It would be interesting to see some more research done into the effects of keeping the legs warm, not just dry, perhaps using thermography. I have dug out the thermotex stable wraps I inherited a few years ago as the article did make me think that they would be helpful in drying his legs quickly, which will at least help me brush off mud and keep them cleaner so in that way the article has a valid point. 

If anyone else has seen any more recent experiments with preventing mud fever, as I think prevention of the bacteria establishing themselves is the critical factor in beating mud fever.
