A group of horses grazing on a grassland. Grey, brown, black and white horses, all wagging tails. Grazing is a type of feeding, in which a herbivore feeds on plants and grasses. Many small selective herbivores follow larger grazers, who skim off the highest, tough growth of plants, exposing tender shoots. For terrestrial animals, grazing is normally distinguished from browsing in that grazing is eating grass or forbs, and browsing is eating woody twigs and leaves from trees and shrubs.Grazing is important in agriculture, in which domestic livestock are used to convert grass and other forage into meat, milk and other products. Grazers-scrapers feed also on microorganism and dead organic matter on various substrates.
