Sudden changes in feed are not ideal as they interfere with the correct functioning of a horse's intestinal flora.
A horse has a very slow digestive system which is poorly suited to receiving large amounts of food.
Before deciding its type of feed, it is important to assess your horse's activity. So, the less it will be worked, the more its feed will be composed of forage.
Its reserves are mainly stored in the fore-quarters (neck) and hind-quarters. The latter is the first indicator for judging a horse's condition (cf. diagram). The neck will be very rigid if the horse is fat, and very supple if it is fit.
For many long years, our predecessors fed their horses with a large amount of cereals, alfalfa, hay and straw.
Horses are herbivores, but did you know that the nutritional value of the grass it eats varies depending on the soil, the variety and, especially, its growth stage?
