A "trough" is a long, narrow container used to hold water or feed for animals, particularly livestock like cows and horses. It is often made of materials such as wood, metal, or plastic and is designed to be durable and easy to clean. Troughs can be found in farms and stables, providing a convenient way to supply food and water to animals. In a different context, a "trough" can refer to a low point in a graph or cycle, such as in economics or weather patterns. For example, in a business cycle, a trough represents the lowest point before recovery begins, indicating a period of reduced economic activity.
