Variety is the spice of life!
One of my small obsessions is watching my horses eat. I love the way they pick and choose so carefully and precisely, how their nose and whiskers work together to sort through a dense mat of green stuff. Negev is an absolute master, a gourmand, who takes a little of this, a little of that till he has 4 or 5 different tastes in his mouth at the same time. And just as you think he’s done, he goes back for a little bit more of one plant before he chews it all up, eyes half closed. When I think of horses who are confined to single species grazing, or fed only and forever on hay, I shudder.
Personally, I think the two most important factors in horse health are movement and variety of diet. Enough movement is essential for the musculo-skeletal system, including the feet, varied diet keeps the motor running at optimum to fuel the movement. With enough variety in the diet a horse can balance his nutritional needs, which vary from day to day, or week to week, and many of those niggly little problems of itching, or nervousness, or runny eyes will clear up. Not to mention the not-so-niggly problems, such as laminitis and metabolic syndrome.
I am lucky -or determined, I didn’t get here overnight!- as I am now living in an environment where it is easy to provide my horses with a wide variety of forage, on a selection of different terrains (different terrain means different mineral content and trace elements). And when I say ‘provide’ I don’t mean they get room service, they have to move a lot to find their food.
This property starts in moist, cool river bottoms with Atlantic vegetation, then strolls up the rocky hillside through oaks, pines, and mediterranean scrub with rough grasses: ideal. However, when I lived in less perfect conditions I used to provide variety by taking horses out to graze on the hedgerows of England or equivalent (depending on the country!. Or I offered herbs and essential oils to provide the secondary metabolites necessary for self-medication, and clays and minerals to provide their non-vegetable needs. If your horse is confined you can add herbs and barks to a feeding ball to keep them entertained and healthy.
I have hours of video of horses eating (did I mention obsessed?), I’ll spare you that. Here is a small clip I put together for my aromatics students, just to illustrate the point.
