Are “normal” skin problems really that ‘normal’?
Last week, Alyson Sharpe (PB Paddock Paradise Livery) and I presented a webinar: “How does grass affect your horse’s skin?”
It was a challenging subject. Some pasture-related skin conditions have recognised explanations, including photosensitisation associated with particular plants or impaired liver function.
But those explanations do not really account for the broader pattern Alyson and I have observed: horses whose skin problems improve substantially after changing their grazing, diet and management.
I remember dealing with ferocious “mud fever” when there was no mud, particularly in late autumn, with cool nights, dewy mornings and sunny days, and again in early February.
Summer meant fly rugs, sprays, gels and endless protection. Rubbing, itching and scabby patches became things to manage. “Cannon crud”, greasy foreheads, greasy material clinging to ear hair, and runny eyes leaving sore skin underneath were all fairly normal things to be addressing as part of general grooming of your horse.
Plus, more serious conditions, mallenders and sallenders added to the daily workload with my heavy weight cob.
It was easy to regard these problems as part of keeping horses. Clean it, cream it, cover it and carry on. Which at the time was what I was doing and feeling pretty good about it.
What changed was how much less skin management my horses needed after moving to my grass free track with late cut meadow hay and a balanced daily feed.
Ultimately my horses issues progressed further than skin issues before I realised what needed to change so now I believe that these skin issues were simply red flags and if I had known better I could have done better sooner than I actually did.
“What is it about grass that causes these problems?” Alyson asked.
My honest answer, I cannot give a scientifically verified explanation for everything we have observed. However, in my view inappropriate forage / pasture creates disturbances to the gut and challenges the immune system. These factors create various responses, hence the grass affected checklist, but skin conditions which are often overlooked and treated topically are signs that diet and management are not working as they should for your horse.
It’s important to note that when my horses lived at grass, they received bucket feeds including a vitamin and mineral supplement, and yet they still struggled. It was changing their whole management, removing grass and feeding hay with a well balanced bucket that brought lasting improvements that the topical care, fly rugs and other paraphernalia did not achieve.
Looking back, those recurring problems were reasons to reassess the system, not simply find another product or cover to put on their skin.
I began the webinar with some photographs showing what good looks like to me.
Here is my 23 year old Glen at a show last weekend, keeping his friend Andrew company. Andrew enjoys the same approach to feeding and management as Glen.
Glen came straight from my muddy track: a simple brush, his mane plaited, and off we went. No bath, coat polish or last-minute lotions and potions.
Both horses looked bright, shiny and comfortable, and thoroughly enjoyed their day out.
