Understanding the difficulty: Winter hay vs. spring grass
As grass matures all by the rising season, the protein content material materials supplies decreases, whereas the fiber fraction and dry matter content material materials supplies enhance, leading to an fundamental lower in digestibility and digestible vitality.
It subsequently is sensible for early spring grass to be larger in protein, and better in merely fermentable carbohydrate content material materials supplies, than the grass used to make hay, which was allowed to develop later into the season earlier than being cut back. In fact, hay could possibly be so much decrease in moisture in contrast with fashionable grass as accurately.
The mixture of those parts gadgets the stage for potential digestive upset when there’s an abrupt change from hay to spring pasture. That’s an infinite draw again, given the general significance of intestine properly being for horses.

Everybody is aware of that virtually all the everyday horse’s dietary nutritional vitamins is likely to be equipped by their forage. So, for example, let’s say there’s a 6% protein distinction between our hay and our spring grass. A rise in forage protein content material materials supplies of 6% equates to solely over a pound of extra protein consumed by the horse day-after-day. That seemingly small change in protein content material materials supplies alone can virtually cowl the protein necessities of the usual horse. Take into accounts that the horse is now consuming that along with what they have been getting from the hay alone.
The an similar goes for varied dietary nutritional vitamins passing by means of the digestive tract. When mixed with the upper digestibility of spring grass resulting from its shortly fermentable fibers, all of it represents a large and doubtlessly abrupt change contained in the inflow of dietary nutritional vitamins into the hindgut. This transformation in nutrient inflow can disrupt the fragile stability of intestine microbial organisms. The terribly specialised and delicate hindgut microbial inhabitants requires time to adapt to feeding modifications to keep away from metabolic components. And so, as with all dietary modifications in a horse’s meals plan, a gradual change is appropriate when transferring from hay to fashionable grass.
