Elderberry, or elder, is a plant that primarily occurs in temperate regions of Europe, Asia, and North America. The elder tree produces small, fragrant flowers and berries that are traditionally used in various culinary and medicinal applications. Both the flowers and the berries can be processed into syrups, jams, and teas, and are often valued for their flavor and aroma.

In animal feed, elder is sometimes used as a natural supplement. For dogs, it can be a source of antioxidants and may help support overall health. For chickens, the flowers are sometimes added to feed to stimulate appetite and promote digestion. For horses, elder may contribute to improved resistance, although its use should always be approached with caution, as not all parts of the plant are safe for consumption.

It is important to emphasize that, while elder may have various benefits, it is always advisable to consult a veterinarian before adding new ingredients to the diet of pets or livestock.
