Loose mineral or ration balancer?
I was asked this the other day, and it is a good question. Both products sit side by side at the feed store, and both are meant to fill gaps in your horse's diet. They are not the same thing.
A loose mineral gives your horse vitamins and minerals. It has almost no protein or calories. It works well for a horse that already gets enough protein and energy from hay. Some people put it out free choice, but horses do not always eat what they need on their own, so I like to see it measured and fed every day.
A ration balancer is a small pellet fed in low amounts, usually half a kilogram to a kilogram a day depending on the brand. It has vitamins and minerals plus good quality protein, including lysine. It adds very few calories. I find it useful for easy keepers, horses on poorer hay, and young or working horses that need more protein than their hay provides.
When I balance a diet, I use the NRC Nutrient Requirements of Horses. The NRC lays out how much energy, protein, lysine, minerals and vitamins a horse needs each day. Those needs change with body weight and with what the horse is doing, whether that is maintenance, work, growth, pregnancy or lactation.
I start with the horse. I look at weight, age, workload and body condition. Then I look at the hay and what it is actually giving the horse, ideally with a forage test. I compare the two and see what is missing. After that I choose a product, and I make sure it fills those gaps without overdoing anything or throwing off ratios like calcium to phosphorus and zinc to copper.
If you are not sure what your horse is missing, or you are feeding three supplements and still guessing, send me a message to book a nutrition consultation.
