Natural ventilation has obvious advantages in that natural forces are used to ventilate buildings, reducing costs for both fans and electrical power. Natural forces include wind moving through, against, and over buildings, as well as thermal buoyancy of warmed air rising inside of the building.

The horse is a non-ruminant herbivore. And like all herbivores, it can fill most of its daily energy requirements by eating plant fiber.

“The biggest benefit of alfalfa for horses is that it tends to be more nutrient-dense than most grasses when harvested at the same stage of maturity,” says Martinson. It typically contains more digestible energy, more crude protein and calcium, and fewer nonstructural carbohydrates (sugars and starches).

Some horse owners express concerns about feeding alfalfa to their horses because they worry about contributing to hot behavior, effects on the calcium-to-phosphorus ratio of the diet, and whether alfalfa causes enterolith formation

Alfalfa is a nutritious forage that can benefit many classes of horses, including those with elevated energy, protein, or vitamin and mineral requirements.Due to its high energy, protein, and calcium content, alfalfa must be carefully added to the diet to avoid dietary imbalances
