A trough feeder is a type of feeding equipment commonly used in agriculture, particularly for livestock such as cattle, sheep, and goats. It consists of a long, open container or trough that holds feed, allowing multiple animals to eat simultaneously. This design helps to minimize feed waste and ensures that all animals have access to food. Trough feeders can be made from various materials, including metal, plastic, or concrete, and are often placed in pastures or barns. They are essential for efficient feeding practices and can be used for both dry feed and liquid supplements, contributing to the overall health and productivity of the animals.
